Welcome Congratulations on your decision to purchase a Tripod Data Systems product. TDS is serious about providing the best possible products to our customers and know that you are serious about your tools. We are proud to welcome you to the TDS family. Survey Pro can be run in three modes: Conventional, Leveling and one of two versions of GPS. The first portion of this User's Manual explains how to get started with Survey Pro no matter which mode you are running in.
Getting Started TDS Survey Pro is available with the following modules, each sold separately: • • • • • • • Standard Pro Basic GPS GPS Robotic Leveling Trimble System Extension Throughout the manual and software, it is simply called Survey Pro. For a listing of which features are included in each product, contact your local TDS dealer. This manual covers the routines that are available in all of the different modules.
User’s Manual Survey Pro Installation Survey Pro is installed from the Installation CD running on a PC. It will load Survey Pro and then install it on the data collector with the next ActiveSync connection. 1. Turn on the data collector and connect it to your PC. If you are using ActiveSync it will attempt to make a connection. 2. With an ActiveSync connection, you will be asked if you want to install TDS Survey Pro. Answering YES will install the application on the Recon.
Getting Started Enter the registration code provided by your TDS dealer in the Registration Code field and tap Register. This will register all of the modules that you have purchased. If there are modules that you feel should be registered but are not, contact TDS tech support. Add-on modules can also be purchased from your local TDS dealer to upgrade your TDS Survey Software.
User’s Manual Data Entry Using a handheld device without a keyboard requires some adaptation but one can get very proficient when using all the shortcuts available to navigate around quickly. Even if you are already familiar with the TDS software, reading this section can help you get the most from your handheld device. TDS SIP Survey Pro offers several alternatives to input characters without a physical keyboard. These methods take the form of an overlay window, called Soft Input Panels (SIPs).
Getting Started TDS allows access to three different SIPs. Since most of the entries relating to surveying will require numerical input, the numerical panel contains oversized digit buttons for ease of use, as well as useful options such as tab (to move between fields), enter, cut, copy, paste, etc. While most SIPs are fixed at the bottom of the screen, TDS Keyboard can be floated over the screen. dragging its grip bar.
User’s Manual Using the Smart SIP Whenever you tap in an edit field, the appropriate SIP will automatically open. The type of edit field where the cursor is placed determines the type of SIP that opens. The SIP will position itself so that it does not cover the edit field. There are three types of edit fields: • Point name edit fields: These default to the numeric TDS SIP. • Alphanumeric edit fields: such as Description, File Name, Layer Name, etc. These default to the alpha TDS SIP.
Getting Started Changing SIPs While the cursor is in an input field, you can select a different SIP to use for entering text into that field and Survey Pro will remember your selection and open the new SIP whenever the cursor is placed into the same type of input field. The same behavior will occur if you switch between the alpha and numeric TDS keyboards. To select a different SIP, tap the up-arrow button next to the SIP icon. A list of all installed SIPs will open. Simply tap on the SIP you want to use.
User’s Manual Angle and Time Conventions Throughout the software, the following conventions are followed when inputting or outputting angles and time: Azimuths Azimuths are entered in degree-minutes-seconds format and are represented as DD.MMSSsss, where: • • • • DD MM SS sss One or more digits representing the degrees. Two digits representing the minutes. Two digits representing the seconds. Zero or more digits representing the decimal fraction part of the seconds. For example, 212.
Getting Started Using Survey Pro Tapping the screen with a stylus is the primary method for interaction with Survey Pro. You can start Survey Pro by tapping the icon, selecting Programs, then selecting Survey Pro. Note: The proper way to exit Survey Pro is by selecting File , Exit from the Main Menu. Exiting in this way guarantees that the settings will get saved properly to the registry. Once Survey Pro is started, the Survey Pro splash screen will open.
User’s Manual 3. Another screen will open where you select some of the job settings. Select the settings that you desire and tap Next > to continue. Note: When creating a new job, it is important that the Units for Distances field be set to the correct units. This allows you to seamlessly switch between different units in mid-job, but problems can arise if these units are inadvertently set to the incorrect units when new data is collected. 4.
Getting Started Navigating Within the Program The starting point in Survey Pro, which appears once a job is open, is called the Main Menu, which is shown here. All the screens that are available in Survey Pro can be accessed starting from the Main Menu. Likewise, closing any screens that are open in Survey Pro will eventually take you back to the Main Menu. The Main Menu consists of two main areas. The upper half of the screen contains a set of large buttons called main menu items.
User’s Manual Command Bar The command bar is the top portion of each Survey Pro screen and it contains buttons that are appropriate for the current screen. All of the possible buttons are described below. About Survey Pro Tapping this button from the Main Menu or selecting File > About Survey Pro will open the About Survey Pro screen, which displays information on the version of Survey Pro that is installed. The Hardware Information button is a shortcut to the Windows System Information screen.
Getting Started Surveying Mode The instrument icon indicates which collection mode the software is running in. There are three possible surveying modes: Conventional, GPS, and Leveling. Tapping this icon will open a list of options to do any of the following: • • Switch to another instrument mode. • Select a different instrument profile. (See the Instrument Settings screen in the Reference Manual for more information.) Quickly access the Instrument Settings screen.
User’s Manual Cancel This button is red in color and closes the current screen without performing the action intended by the screen. Close This button is green in color and closes the current screen. Settings This button opens the Settings screen associated with the current screen. GPS Status This is used to view the current status and access the settings for a GPS receiver when using the GeoLock feature (Page 153).
Getting Started Parts of a Screen Many screens share common features. To illustrate some of these features, we will examine parts of the Backsight Setup screen, shown here. You can access the Backsight Setup screen by selecting .Survey , Backsight Setup from the Main Menu. Input Fields An input field is an area where a specific value is entered by the user.
User’s Manual Power Buttons The Backsight Setup screen contains two power buttons. Power buttons are typically used to provide alternate methods of entering or modifying data in an associated field. To use a power button, simply tap it. Once tapped, a dropdown list will appear with several choices. The choices available vary depending on with which field the power button is associated. Simply tap the desired choice from the dropdown list.
Getting Started Scroll Buttons Button. When a button label is preceded with the symbol, it indicates that the button label can be changed. Each tap of the symbol will toggle through the various button label options and the corresponding field associated with it. For example, in the Backsight Setup screen, the backsight can be defined by a point or a direction by toggling the scroll button between BS Point and BS Direction . Special Point Symbols Some field labels are preceded with a special symbol.
User’s Manual Input Shortcuts Distances and angles are normally entered in the appropriate fields simply by typing the value from the keypad, but there is a shortcut that can simplify the entry of a distance or angle. If you want to enter the distance between two points in a particular field, but you do not know offhand what that distance is, you can enter the two point names that define that distance separated by a hyphen.
Getting Started 1. When the job is configured for International Feet or US Survey Feet, it is assumed that the distance entered is in the same units as the job is configured for. 2. If the job is configured for meters, it is assumed that the distances entered are in International Feet and will be converted to meters when the cursor leaves the current field. (You cannot use this method to enter a metric distance in fractional format.) 3.
User’s Manual Point List Editor Many screens contain a To/From… button, which accesses the Select Point(s) screen that allows you to enter a simple list of points or a list of points that describe a line that can contain curves. Examples of how to enter different lists of points are displayed in the lower portion of the screen. Once the list is entered, tap to return to the previous screen. Note: Spaces in point lists are ignored. They are only used in the examples for clarity.
Getting Started Entering Distances in Other Units When a distance is entered in a particular field, it is normally entered using the same units that are configured for the current job, but distances can also be entered that are expressed in other distance units. When entering a distance that is expressed in units that do not match those configured for the job, you simply append the entered distance with the abbreviation for the type of units entered.
User’s Manual Quick Pick The button is called the Quick Pick button and is available at the bottom of most screens in Survey Pro. This button is used to quickly access any of several commonly-used routines. The list of routines available from the Quick Pick button can be customized and sorted in any order. To access a screen with the Quick Pick button, first tap and then tap the desired routine.
Getting Started the Move Up or Move Down buttons. (Any other routines in the Quick Pick list can also be repositioned in this way.) To remove a routine from the Quick Pick list, select it and tap the <-- Remove button. Tapping the Defaults button will revert the custom list back to the default list. Since any changes will be lost, a prompt will first ask if you are sure. Smart Targets Survey Pro has the ability to create and store custom configurations for any number of prisms or other target types.
User’s Manual Manage Smart Targets Select Manage Smart Targets from the same drop-down list described above to access the Manage Smart Targets screen. From here you can create a new custom Smart Target or edit any existing Smart Target. Survey Pro includes two foresight Smart Targets called My Prism and My Reflectorless, respectively and one backsight Smart Target called My Backsight Prism.
Getting Started The Smart Target Name you provide will be shown in the drop-down list when you switch between Smart Targets. The Target Type field determines how the EDM will be configured on the total station when taking shots to the Smart Target.
User’s Manual Pro and on the total station, it will be applied twice resulting in incorrect distance measurements for every shot. If you are using a robotic total station that supports prisms that output a target ID, the Use Target ID field will be available where you can specify the target ID for the Smart Target. If Use For Search is available and selected, the total station will only look for the Target ID when it is searching for the target.
Getting Started There are different map views depending on from where the map view is accessed and they can display slightly different information such as a vertical profile. The main map view is accessed from the Main Menu by tapping the button at the bottom of the screen in the command bar. If you are using basemaps, it is from this map view where the basemaps are managed. All other map views are accessed by tapping the variety of screens.
User’s Manual Increase Vertical Scale: is only available when viewing a vertical profile. Each time it is tapped, the vertical scale of the view is increased. Decrease Vertical Scale: is only available when viewing a vertical profile. Each time it is tapped, the vertical scale of the view is decreased. Zoom Preview Button: will display only the points that are currently in use (only available from certain map view screens). Map Display Options: accesses the Map Display Options screen, described below.
Getting Started • Before you can use a basemap in Survey Pro, you need to copy the appropriate basemap files from a PC to the same directory where your current job is located. If the basemap files are stored in a different directory and then added to the current job, the files will be copied to the job’s directory. • If you use the Save As routine and save the current job to a new directory, any basemaps associated with that job will be copied to the new location.
User’s Manual Raster basemap drawn first. Vector basemap drawn last. Resulting map view with both basemaps in view. 6. To change the order of the basemaps in the list, select a basemap and tap the Move Up or Move Down buttons to move it up or down in the list, respectively. 7. To remove any basemap from the list, select it and tap Remove . This will remove the basemap from the list and un-associate it from the current job. (This will not delete the corresponding basemap file.) 8.
Getting Started The Settings Screen The Settings screen is used to control all of the settings available for your surveying instrument, current job, and Survey Pro software. It contains several index card-style tabs. Each card contains different types of settings. Most of the settings remain unchanged unless you deliberately change them, meaning the default settings are whatever they were set to last.
User’s Manual File Management and ForeSight DXM Survey Pro uses a variety of files to store data and information about your project. The files include the main data file, the .JOB file, and the raw data file, the .RAW file, and several other supplementary files that Survey Pro can use for additional information. To help manage this data and to supplement Survey Pro capabilities, TDS has an office product called ForeSight DXM.
Getting Started When you specify points to use for any reason within Survey Pro, the software will read the coordinates for the specified points from the job file. Whenever you store a new point within Survey Pro, the point is added to this file. A job file can be edited on the Survey Pro when using the Edit Points screen. Since a job file is binary, it requires special software for editing on a PC, such as TDS Survey Link. It can also be converted to or from an ASCII file using Survey Link.
User’s Manual Control Files The current job can be configured to access the points from another job stored on the data collector. When the current job is using points from another job, that other job is called a Control File and the points in the control file are called Control Points. (Any non-point objects in a control file are always ignored.
Getting Started Some users prefer to keep a set of known points in a separate control file when repeatedly working on new jobs in the same general area. That way when they return to the job site, they can create a new job, but select the external control file to easily have access to the known control points. Once an external control file is selected, the control points can be used in the same way as the job’s points with the following exceptions: • An external control file has read only attributes.
User’s Manual must be careful how the file is saved. By default, a word processor will store additional non-ASCII data in a file making it incompatible as a description file. However this can be avoided if you use the File > Save As… routine from your word processor and choose a Text Only format as the type of document to save. For more information on creating a text file using a word processor, refer to your word processor’s documentation.
Getting Started To use a description from a description file, simply start typing that description in any Description field. (You can experiment with descriptions in the .Survey , Traverse / Sideshot screen.) Once you start typing a description, a dropdown list will appear displaying all of the descriptions that are in the description file along with all the descriptions that are assigned to existing points in the current job in alphabetical order.
User’s Manual shown above, lo would be replaced with Lodgepole Pine once the cursor was moved to another field. You can combine a description with any other text, or combine two descriptions by using an ampersand (&). For example, entering Tall&do would result in a description of Tall Douglas Fir. Entering b&oa would result in a description of Big Oak Tree. This method also works when spaces are included with the ampersand. For example, entering b&oa would have the same result as entering b & oa.
Getting Started Feature Codes As explained above, a description or descriptor codes can be used to help describe a point prior to storing it, but this can be a limited solution for describing certain points. Survey Pro also allows you to describe any object using feature codes. Feature codes can be used to describe objects quickly and in more detail than a standard text description, particularly when data is collected for several points that fit into the same category.
User’s Manual Features The primary part of a feature code is called a feature. Features generally describe what an object is. Two types of features are used in Survey Pro: points and lines, which are described below. When assigning a feature to data that was collected in Survey Pro, only features of the same type are available for selection. For example, if selecting a feature to describe a point in a job, only the point features are displayed.
Getting Started • Menu Attributes A menu attribute is an attribute that is selected from a pulldown menu rather than typed in from the keypad. Menu items can also have sub-menu items. For example, you could have a feature labeled Utility with a pull-down menu labeled Type containing Pole and Pedestal. There could also be submenu items available that could be used to describe the pole or pedestal in more detail.
User’s Manual Layers Survey Pro uses layers to help manage the data in a job. Any number of layers can exist in a job and any new objects can be assigned to any particular layer. For example, a common set of points can be stored on one layer and another set can be stored on a different layer. The visibility of any layer can be toggled on and off, which gives full control over the data that is displayed in a map view. This is useful to reduce clutter in a job that contains several objects.
Getting Started Similarly, whenever a new job is created, a Points layer is automatically created and selected as the active layer. The active layer is the default layer where any new objects will be stored. Managing Layers You can configure Survey Pro to prompt for a layer whenever an object is stored. If this prompt is turned off, any new objects that are stored will simply be stored to the active layer. There are three cards within the Job Settings screen to configure this prompt.
User’s Manual Changing a Layer Name or Visibility Selecting a layer and then tapping Edit… opens the Edit Layer dialog box where the name and visibility can be changed for the selected layer. You can also edit a layer by double-tapping on it. (Layer 0 cannot be renamed.) Deleting a Layer You can only delete an empty layer. If a layer contains any objects, they must first be moved to a different layer. To delete a layer, select the layer and tap Delete . (Layer 0 cannot be deleted.
Getting Started Working with 2D Points Most people work with 3D points, but Survey Pro also allows you to work with 2D points (points without elevations). You can also work with a combination of both 3D and 2D points. It is important to remember that data collected from a 2D point will also be 2D, so care should be taken when working without elevations. To assist the user, various warnings will appear when working with 2D points.
User’s Manual “Note: Selected occupy point has no elevation. All points computed with this point will have no elevation computed for them.” An elevation adjustment on a traverse containing any 2D points is not possible. If an attempt is made to do so, the following message is displayed: “Traverse contains a 2D point. Cannot adjust elevations.” Point Stake When performing point stake using a 2D point, no cut/fill information is provided.
Getting Started Polylines Lines can be added to your project that can represent anything such as a roadway, a building, or a lot boundary. These lines are referred to as polylines. Polylines can be compared to the point lists used in other TDS data collection software. They can consist of several individual curved and straight sections. A point must be stored in the project for all the locations on the polyline where a new section begins and ends.
User’s Manual Alignments Alignments are similar to polylines in that they define specific lines in the current job and typically describe the centerline of a road. An alignment can then be used in the Offset Staking, Offset Points, Offset Lines, and Slope Staking screens. Unlike polylines, alignments do not need points for the locations where the alignment changes (called nodes). Alignments are created by separately defining the horizontal and vertical details of a line.
Getting Started Creating an Alignment In this step-by-step example, we will create an alignment that has all the possible horizontal and vertical segment types. 1. Select .Job , Edit Alignments from the Main Menu. If any alignments exist in the current job, they will be listed in this screen. An existing alignment can then be edited or deleted, but for this example, we will create a new alignment. 2. Tap New… to create a new alignment.
User’s Manual Horizontal Alignment 4. Tap the HAL (Horizontal Alignment) tab and then tap the Insert button. This will open the Edit Segment screen where the first horizontal alignment segment can be defined. 5. Tap the Line tab to insert a straight line segment. Enter a Length of 100 and an Azimuth of 0. 6. Tap to add the segment to the horizontal alignment. You will return to the Edit Alignment screen where the new segment is displayed.
Getting Started 7. Tap the Insert button again and then tap the Arc tab to insert a horizontal curve. 8. Enter a Radius of 100, a Delta of 45 and select a Right turn. Check the Make this segment tangent to previous checkbox so that the curve will be positioned so the entrance to the curve is tangent to the end of the previous segment. 9. Tap to add the segment to the horizontal alignment.
User’s Manual Note: When creating a new horizontal segment and using the Make this segment tangent to previous option, the new segment will appear in the Edit Alignment screen tagged with a (P) (see picture). This means that if the previous horizontal segment is edited or deleted, thus changing the orientation, all subsequent horizontal segments that have the (P) tag will also be adjusted so they will remain tangent to the previous segments.
Getting Started 16. Tap the Insert button again and then tap the V. Curve tab to insert a parabolic vertical curve. Enter a Length of 250 and tap the Get Previous Grade button to automatically set the Start Grade to the ending grade of the previous segment. Enter an End Grade of -2%. 17. Tap to add the segment to the vertical alignment. 18. Tap the General tab and enter a Description of Roadway.
User’s Manual 19. Tap from the Edit Alignment screen to return to the Add/Edit Alignments screen where the new alignment is stored and displayed. You have now completed a new alignment using all the available types of segments. You can select the new alignment for use in the Offset Staking, Offset Points, Offset Lines and Road Layout routines.
Conventional Fieldwork This section will explain how to get started using Survey Pro to collect data from a total station and perform stake out. It is assumed that you are familiar with the operation of your total station. The first section describes the backsight setup procedures for various scenarios. The next section walks you through the steps involved to setup and perform a simple side shot and traverse shot. The third section walks you through a simple point-staking example.
User’s Manual – Conventional Mode Scenario One You know the coordinates and locations for two points on your lot and want to occupy one and use the other as a backsight. Solution 1. Create a job using the coordinates for one of the known points as the first point. 2. Use the Edit Points routine to add a second point using the coordinates for the remaining known point. 3.
Conventional Fieldwork Scenario Two You have found two points on your lot and know the azimuth between them, but you do not have coordinates for either. Solution 1. Create a job using the default coordinates for the first point. 2. From the Backsight Setup screen, set the Occupy Point field to the point that was just created. 3. Setup the total station over the point where the known azimuth is referenced. 4. Toggle the .BS Direction. / .BS Point. button to BS Direction.
User’s Manual – Conventional Mode Scenario Three You have one point established on your lot and you know the azimuth to an observable reference. Solution 1. Create a job using the coordinates of the established point for the first point. If the coordinates are unknown, accept the default coordinates. 2. From the Backsight Setup screen, set the Occupy Point field to the point that was just created. 3. Setup the total station over the established point. 4. Toggle the .BS Direction. / .BS Point.
Conventional Fieldwork Scenario Four You have only one known point on a job. Solution You have two options in this situation. One, you can assume an azimuth for an arbitrary backsight reference and rotate the job later using the Rotate routine once you have determined the actual orientation. Secondly, you can use the Sun Shot routine to determine an azimuth to an arbitrary reference.
User’s Manual – Conventional Mode Summary In general, you would follow these steps when you begin working on a job. 1. Create a new job or open an existing job. 2. Setup over the Occupy Point. 3. Aim the total station toward the backsight and zero the horizontal angle on the instrument. 4. Fill in the Backsight Setup screen and tap Solve… to open the Backsight Solved screen. 5. Confirm the BS Circle value is zero and tap Send Circle to zero the horizontal angle on the instrument, then tap .
Conventional Fieldwork Data Collection Example This section illustrates the necessary setup and usage of the Traverse / Side Shot screen, which is the primary screen used during data collection. We will create a new job and manually add another point to the job to use as a backsight. We will run in Manual Mode so the shot data must be entered manually.
User’s Manual – Conventional Mode c. Enter any job name that you wish in the Job Name field and tap Next > . d. For this example, simply accept the default job settings and tap Next > . Note: When creating a new job, it is important that the Units for Distances field be set to the correct units. This allows you to seamlessly switch between different units in mid-job. Problems can arise if these units are inadvertently set to the incorrect units when entering new data.
Conventional Fieldwork e. Accept the default coordinates for the first job point by tapping Finish . You will return to the Main Menu. 2. Check the job settings. a. Tap Job , Settings from the Main Menu to open the Settings screen. b. Tap the Instrument tab if it is not already selected and make sure the Manual Mode profile is activated. If the symbol is not shown next to it, select Manual Mode and tap Activate .
User’s Manual – Conventional Mode c. For this example, tap the Surveying card and uncheck all the checkboxes. d. Tap (OK) to save the job settings. 3. Add a backsight point to the job. a. Select Job , Edit Points from the Main Menu. b. Tap Insert… and enter a new point using the General and Location cards with the following values, as shown: Point Name: 2 Northing: 5050 Easting: 5050 Elevation: 100 Description: Backsight and then tap .
Conventional Fieldwork 4. Set up your backsight. In this example, we will setup on Point 1 and backsight Point 2, which was just created. a. Access the Survey , Backsight Setup screen. b. In the Occupy Point field, enter 1 as the point name. Tip: You can also select an existing point from a map view or from a list by using the power button. c. Enter an HI and HR of 5 feet each. d. Toggle the .BS Direction. / .BS Point. button to BS Point. and enter 2 as the point name. e.
User’s Manual – Conventional Mode i. Tap to exit from the Backsight Solved screen. The map view will open showing your current setup. j. Tap (Close) to continue. Performing a Side Shot 5. Access the Survey , Traverse / Sideshot screen and fill in the appropriate fields. The backsight information is displayed in the lower portion of the screen. At this point, it is assumed that your total station is over the occupy point and its horizontal angle was zeroed while aiming toward the backsight. a.
Conventional Fieldwork computed and stored. The Foresight point will automatically advance to the next available point name and the information from the last shot is displayed on the screen. d. You can see a graphical representation of the previous shot by tapping the Map tab. See Page 24 for more information on the Map View. Performing a Traverse Shot 6. The steps involved in performing a side shot are nearly identical to performing a traverse shot.
User’s Manual – Conventional Mode The new point is computed and stored and the Traverse Now or Later prompt will open asking if you want to advance to the new point now or later. For this example, tap the .Traverse Now. button. The New Occupy Point dialog box will open, shown here, which displays details of the new setup. You can see that the previous foresight point is now the current occupy point and the previous occupy point is now the current backsight point.
Conventional Fieldwork When out in the field, you would now move your total station over the new occupy point, aim it toward the previous occupy point (the current backsight), enter the correct instrument height in the Height of Instrument field and tap .Send Circle to Instrument . This would update the Traverse / Side Shot screen and set the total station’s horizontal angle to zero where you are then ready to collect more data.
User’s Manual – Conventional Mode Stakeout Example When setting up to perform stakeout, the requirements are nearly the same as with data collection. You need an existing occupy point, backsight point or direction, and a foresight. The main difference is existing points are being located during stakeout rather than new points being collected. In the example below, all of the steps required to perform a simple point staking job are explained from the initial setup to the staking itself.
Conventional Fieldwork b. Tap the file name that was created earlier listed in the Open Recent Job list and then tap .Open . The coordinates for that job are shown here. 2. Set the job settings. (Only the settings that affect this example are covered here.) a. Select Job , Settings from the Main Menu. b. Tap the Instrument tab if it is not already selected and make sure the Manual Mode profile is activated. If the symbol is not shown next to it, select Manual Mode and tap Activate . c.
User’s Manual – Conventional Mode a. Access the Survey , Backsight Setup screen. b. In the Occupy Point field, enter 1 as the point name. c. Toggle the .BS Direction. / .BS Point. button to BS Direction. and enter 0 as the backsight direction. d. Enter an HI and HR of 5 feet. e. Leave the Fixed HR at Backsight field unchecked. f. Tap Solve… to open the Backsight Solved screen. g. Confirm that the BS Circle value is zero. If not, change it to zero. h. Tap the Send Circle button.
Conventional Fieldwork i. Tap (OK). The Map View will automatically open showing your current setup. Tap (Close) to continue. Staking Points 4. Stake the first design point (Point 2). a. Access the Stakeout , Stake Points. screen from the Main Menu. The backsight information is displayed near the bottom of the screen. At this point, it is assumed your total station is over the occupy point and its horizontal angle was zeroed while aiming toward the backsight. b.
User’s Manual – Conventional Mode c. The second Stake Points screen will open that displays all of the information needed to locate the design point. When connected to a total station, you would turn the total station horizontally to 45°00’00”, vertically to 90°00’00” and send the rod man out about 70 feet before continuing. Tap the Stake >. button to continue to the third screen. d. With a Height of rod of 5, tap the Shot. button. (See the Reference Manual for an explanation of the other fields.) e.
Conventional Fieldwork f. The Stake Points screen will show the necessary FORWARD / BACK and Go RIGHT / Go LEFT information that the rod man must move in order to be located over the design point. In this example, the Go RIGHT value indicates 0, which means the rod is precisely on the line between the total station and the design point. The BACK value indicates 0.711, which indicates that the rod must move back (away from the total station) 0.711 feet to be over the design point.
User’s Manual – Conventional Mode 5. Stake the next design point. a. We want to stake the next design point in the project. The Design Point should automatically advance by the Increment value. Make sure the Design Point is set to 3 and then tap Solve > to open the second Stake Points screen. b. The information needed to locate the next design point is displayed.
Conventional Fieldwork d. The rod man needs to move back by 0.2 feet to be over the design point. Rather than take another shot, we will instruct him to use a tape and place a stake at that location. Tap the .Store/Tape… button to store the point. e. Enter the following data in the Store Point (Tape Offset) screen: Point Name: 6 Description: Staked Tape Out/Tape In (+/-): 0.2 and then tap . This will result in coordinates for the stored point that are 0.
User’s Manual – Conventional Mode Surveying with True Azimuths Some people need to collect all of their horizontal angles in the form of azimuths. Survey Pro can help automate this process by computing the backsight azimuth after each new setup in a traverse and updating the backsight circle and total station’s horizontal angle accordingly. 1. You can setup on any existing point and use any other point in the job as a backsight if the coordinate system is properly aligned with true north.
Conventional Fieldwork 8. Tap Send Circle . This will set the backsight circle as the horizontal angle in the total station and set the same angle as the Backsight Circle value. This angle will then be subtracted from all horizontal angles received from the total station. 9. Begin your survey. When you traverse to a new point, the New Occupy Point dialog box will open showing you the azimuth computed to the new backsight point from the new occupy point.
Road Layout Overview The Road menu contains a powerful set of routines that allow you to enter and modify road layout information and then stake the road in the field. The road staking routines allow you to stake any part of the road or slope stake the road. There are four basic components of a road: The Horizontal Alignment; the Vertical Alignment; Templates, and a POB. All of these components are described separately below and each is a required component to a complete road definition.
User’s Manual – Conventional Mode and slope or change in elevation. Templates can contain as many segments as needed, but must have at least one segment. Each segment describes one component of the cross section such as the roadbed, curb face, top of curb, ditch, etc. Each road alignment can contain as many templates as required to define the roadway, but all the templates used on one side of the road must have the same number of segments.
Road Layout POB The POB designates the location in the current job where the alignment starts. The POB can be defined by an existing point or specified coordinates and can be changed at any time. The VAL’s start station elevation will be set from the POP. Road Component Rules The following section defines how the various components described above work together to form the road. This information is important because how each component reacts to the other component affects the shape of the resulting road.
User’s Manual – Conventional Mode • Template segments must have a name. The template editor provides fields to enter the segment name. 2. Any two templates without intervening Widening or Super Elevations will transition. • This means that each template segment will transition at a linear rate from its existing offset from the centerline to the new offset from the centerline as defined by the new template. 3.
Road Layout • A previous Template. 4. Super Elevation ending slope value and Widening ending width value must match the first segment value defined by: • A following Super Elevation or Widening. (Priority) • A following Template. • Exception: if the Widening or Super Elevation is the last element in the road, it’s end transition value does not have to match anything. 5. Super Elevation and Widening ending stations must be greater than their beginning stations. 6.
User’s Manual – Conventional Mode Road Rules Examples Figure 1 Overhead view of a template-to-template linear transition Figure 2 Template to Widening Transition 88
Road Layout Figure 3 Widening to Template Transition Figure 4 Widening to Widening Transition 89
User’s Manual – Conventional Mode Figure 5 Template Inserted Into A Widening Area Figure Descriptions Figure 1 shows an overhead view of a simple transition from one template to another. Notice the linear transition of one template segment end node to the next. Figure 2 shows an overhead view of a basic template to widening transition. The widening’s first segment width for the start station must match the first segment width of the previous template.
Road Layout segment now take on the shape of the inserted template. The figure shows a widening where the start width is the same as the end width but having the widening use the same start and end width is not required. The first segment of the template will be adjusted to match whatever the widening says the width of the first segment should be at the station where the template is inserted. Also notice in Figure 5 that we have defined a widening with the start width the same as the end width.
User’s Manual – Conventional Mode Creating Templates The information for a single template is stored in a separate file with a TP5 extension. Template names are limited to eight characters plus the extension so that they can be used in DOS-based data collectors. Each template stores information on the cross section for one side of the road. A road can have as many templates as necessary, but each side of the road must only use templates with the same number of segments.
Road Layout 3. Tap Insert… . This will open the Edit Segment dialog box. Enter the following information to define the first segment, which will be a 20-foot wide roadbed with a –2% slope.

The next screen that opens is identical to the screens used in point staking, since that is essentially what is occurring at this point. If you are not familiar with Point Staking, refer to Page 75. 11.
User’s Manual – Conventional Mode Slope Staking the Road The road slope staking procedure is nearly identical to the non-road layout slope staking routine described on Page 152. The main difference is the road layout templates can contain more segments, which modifies the options of where the hinge point should be located depending on if a cut or a fill is required. 1. Tap Roads, Slope Staking to open the Road Slope Staking screen. 2. Tap the Tap Road… button to open the Tap on a Road screen.
Road Layout 9. Tap the Fill Hinge Points tab to define where the hinge point will be computed in areas that require a fill. Use the << and >> buttons to select the desired segment. (The hinge point will be computed at the end of the selected segment.) 10. Now tap the Cut Hinge Points tab and define where the hinge point will be computed in areas that require a cut in the same way as you did in the previous step.
User’s Manual – Conventional Mode 11. Tap the Stake CP > button to continue to the next screen where the catch points at the current station can be located. This screen is identical to the screens used in the non-road layout slope staking routine. If you are not familiar with these screens, refer to Page 159. 12.
Road Layout Two of the stakeout settings should be considered when using a station equation: • When Stake "Corners", Not Just Even Intervals is checked, the location where the stationing changes will be considered a corner and will be included as you advance forward. • When Use Perfect Stationing is checked, the perfect stationing will always be computed using whichever stationing that you are currently staking.
DTM Stakeout The Stake DTM routine allows you to stake an area and get cut/fill information between the point being staked and a reference DTM surface at the same horizontal coordinates. You can also obtain volume information between the surface being staked and a specified reference elevation or the reference DTM surface. Reference DTM Surface DTM Stakeout requires a DTM surface that defines the reference elevations for the area that you plan to stake.
User’s Manual – Conventional Mode Set Up the Job 1. If your reference layer is defined by a DXF or DTM file, it must first be loaded into the data collector. 2. From the Main Menu, tap Stakeout , Stake DTM to open the Stake DTM screen. 3. In the DTM Source field, select if your DTM reference surface will be defined by a Layer or File and then select the layer or tap the power button, then Browse and select the appropriate DTM or DXF file.

The Store button will store the last point shot. The Result card displays additional information about the last stake point and the Centerline card displays information related to the last stake point in relation to the centerline, if selected earlier. View the DTM 17. Tap View… to access the 3D View screen.
DTM Stakeout Note: The cut/fill values accessed from the Volume button are total volume differences between the DTM surface being staked and either the reference DTM surface, or a reference elevation (plane). The cut/fill values displayed in the Result card of the second Stake DTM screen are vertical distances between the current stake point and the reference DTM surface at the same horizontal coordinates. The button toggles to display or hide the point names and descriptions in the 3D view.
User’s Manual – Conventional Mode When the Display Difference from Ref. DTM checkbox is unchecked, the Datum field can be set to a reference elevation. Cut and fill volumes in the 3D View screen will then be based on the difference of a horizontal plane at the elevation specified here and the non-reference DTM surface. The View Direction (from view point to the center) settings allow you to specify the exact horizontal and vertical angle in which to view the DTM surface. 19.
Other Tutorials This section describes how to use several of the routines in Survey Pro. Each example outlines the procedure to use a particular screen. The examples are written in a general way so the user can use their own data to become familiar with the routine. Import / Export The Import routine allows you to add the coordinates from any job to the current job, or import LandXML data.
User’s Manual – Conventional Mode If importing coordinates from a source, such as an HP 48, where you are not sure if the units are in International Feet or US Survey Feet into a job that is set to International Feet or US Survey Feet, you will usually just want to import them without any conversion being performed. To do this, be sure to select the same distance units for the source file as those set for the current job. Importing *.
Other Tutorials 5. The Import CR5 dialog box will open where you must specify the distance used in the file being imported. Select the correct distance and then tap . (See warning above.) If any of the point names in the source file match a point name already in the current job, the Confirm Point Replace dialog box, shown here, will open asking you what you want to do. Make the desired choice to continue. If a duplicate point is encountered (duplicate name and coordinates), it will be ignored.
User’s Manual – Conventional Mode Importing LandXML Files Survey Pro gives you the ability to import the following objects from a LandXML file: Points Both named and un-named (anonymous) LandXML points will be imported as Survey Pro points. Like in other import coordinate functions, if an imported point name conflicts with an existing point name, a prompt will open asking if you want to rename the imported point or overwrite the existing point.
Other Tutorials Features The only feature data that is imported from a LandXML file are TDS feature attributes. Importing a LandXML File 1. With the job open that you want to add LandXML objects to, select .File , Import from the Main Menu. 2. In the Type field of the Import screen, select LandXML Files (*.xml). 3. Tap the desired LandXML file that you want to import and then tap . 4. The first of two configuration screens will open.
User’s Manual – Conventional Mode 5. Tap Next to continue to the second screen. When the Import polylines, alignments and parcels checkbox is checked, everything in the LandXML file that can be imported will be imported. When this is unchecked, only the points will be imported. When Import parcels to the specified layer is checked, the parcels will be imported to the specified layer. All other imported objects will still be stored to the layer(s) defined in the previous screen.
Other Tutorials Import Control The Import Control routine is a solution for people that are used to using control files with versions of Survey Pro prior to Version 4.0. The Import Control routine is nearly identical to the Import routine with the primary exception that the imported points are always stored to a special layer called CONTROL.
User’s Manual – Conventional Mode Exporting Coordinates The steps below will copy selected points from the current job to a new job in a specified file format. 1. Select .File , Export from the Main Menu to open the Export screen. 2. Select the type of file you are exporting coordinates to and tap Next> . 3. You can select the desired points to export using any of the following buttons: • Tap Points… allows you to select points by tapping them from a map view.
Other Tutorials Repetition Shots A repetition “shot” consists of one or more sets. A set consists of four individual shots; direct and reverse shots to a backsight and a foresight. The result of a repetition shot is to store the foresight point using average coordinate values that are computed from all the shots taken. Repetition shots can be performed with a variety of options. This section explains how to perform a repetition shot and the different options available.
User’s Manual – Conventional Mode 3. Set the Horizontal, Zenith, and Distance Tolerances in the appropriate fields. The direct shots for each set are compared to the corresponding reverse shots. If any of the angles or distances exceeds the specified tolerances, the Repetition Error dialog box, shown here, will open that asks what you want to do. You have the following choices: • Retry : Re-shoot only the last set. • Continue : Continue and use the shot anyway.

User’s Manual – Conventional Mode 4. Prompts will open after every shot that instruct you on which point to shoot next and when you when you need to flop the scope. If at least three sets were performed, the Average (of) and Worst Residual fields will be filled in after the final shot is taken. The Average (of) values are simply average measurements for all of the shots taken. The Worst Residual is the angle or distance measurement that varied the most from the average from all the shots taken. 5.
Other Tutorials Radial Sideshots The Radial Sideshots screen is used to perform repetition shots to a backsight and any number of foresights (side shots) from the same occupy point. The behavior of the routine is a cross between the Repetition Shots routine (Page 127) and the Multiple Sideshots routine. A single set in the Radial Sideshot routine starts with a direct shot to your backsight followed by a shot to each foresight.
User’s Manual – Conventional Mode Note: When using a robotic total station and Enable Automatic Repetition is checked in the Radial SS Settings screen, only the direct (Face 1) shots for the first set will need to be shot manually. All remaining shots will be performed automatically. The Shooting Sequence is where you choose to shoot all Face 2 side shots in the same order as the Face 1 shots (B>F1>..>Fn^F1>..>Fn>B), or in reverse order (B>F1>..>Fn^Fn>..>F1>B).
Other Tutorials 5. Tap Shoot to take a side shot. Once the shot is completed, the Results screen, shown here, will be displayed. You are now provided with three option: • Tap Done with SS > if you are finished taking all Face 1 side shots for this set and continue to Step 6. • Tap Shoot if you want to throw out the results for this shot and re-shoot it. • Tap Next SS> if you want to shoot another new side shot in Face 1. You will then repeat Step 4 for the new point.
User’s Manual – Conventional Mode 7. When all shots for every set is complete, the lower right button will be labeled Done > . Tapping it will compute and store all the side shots.
Other Tutorials Shoot From Two Ends The Shoot From Two Ends screen is used to provide more accurate vertical closure to a traverse. The routine requires that after the foresight is shot, its location is not computed until after the foresight point is occupied and a second shot is taken to the previous occupy point. Once the second shot is complete, the coordinates for the original foresight are computed from an average of both shots. BS Shot 1 Shot 2 1.
User’s Manual – Conventional Mode Offset Shots Three individual screens are used to perform offset shots. These include the Distance Offset screen, Horizontal Angle Offset screen, and Vertical Angle Offset screen. Offset shots are generally performed to compute coordinates for points that cannot easily be occupied by the rod. The offset routine that you choose will depend on your situation. Each routine is explained below.
Other Tutorials 4. Enter a positive offset distance in the Horz Dist Offset field if the offset to the new point is behind the rod location (from the total station’s point of view), or enter a negative offset distance if the new point is in front of the rod location. 5. If the new point is at a different elevation than the rod location, enter the a positive vertical offset in the Elevation Offset field, or a negative vertical offset if the new point is below the rod location. 6.
User’s Manual – Conventional Mode 1. From the Main Menu, tap .Survey , Horz Angle Offset . If you have not already setup your backsight, you will need to do so before the Horizontal Angle Offset Shot screen will open. 2. The rod person should position the prism to the side of the location of the new point so that the angle formed by the new point, the prism, and total station form 90°. (See illustration.) 3. With the total station aimed toward the new point, tap the Aim Center button.
Other Tutorials 2. With the prism positioned directly below the location of the new point, aim the total station at the prism and tap Shoot Prism . 3. Aim the total station at the new point and tap Aim Zenith . (Only a zenith angle is measured during this shot so a prism is not necessary.) A new point will be stored with the same northing and easting as the rod location, but with a different elevation.
User’s Manual – Conventional Mode Performing a Resection Setup the total station over the location where you want to compute coordinates. Be sure that at least two known points are in view from this location. (The known points must already be stored in the current job.) 1. Tap .Survey , Resection from the Main Menu. 2. Enter the occupy point name that you want to compute in the Store Pt field. 3.
Other Tutorials With this screen filled in correctly, aim toward the next resection point and tap the Take Shot… button to shoot the specified resection point. 9. Repeat Steps 7 through 9 until every resection point is shot. After the final shot is completed, the Save Point screen will open where you can specify a description for the new point. 10. Tap to return to the Resection screen.
User’s Manual – Conventional Mode Solar Observations The Solar Observation screen is used to compute the azimuth to an arbitrary backsight based on the position of a celestial body, typically the sun. You can either use the time set in the system clock on the Survey Pro or an external timepiece. Whichever you choose, you should calibrate it against Coordinated Universal Time shortly before performing the solar observation. An accurate timepiece is critical when performing solar observations.
Other Tutorials Performing a Sun Shot 1. Setup over a point with known or assumed coordinates and aim the total station at the backsight point to which you will determine the azimuth. 2. From the Main Menu, select .Survey , Solar Observation . 3. A dialog will open asking you to select an observation method and tap . For this example we will select the Find Azimuth Using Ephemeris Data option since it contains a couple additional steps. 4. Enter the latitude and longitude for your occupy point in the Lat.
User’s Manual – Conventional Mode • Check the Correct to State Grid checkbox if you want the computed azimuth corrected to align with the local state plane coordinate system. Note: The Central Meridian and Zone Constant values for the United States are provided in Appendix A of the Reference Manual. 7. Refer to a current ephemeris and fill in the remaining five values. When the screen is correctly filled in, tap the Shots tab.
Other Tutorials 10. WITH A SOLAR FILTER INSTALLED, aim ahead of the path of the sun so that the trailing edge has not yet contacted the vertical crosshair in the scope and tap Take Shot to record the current horizontal angle. Get local time now! 11. Watch the movement of the sun in the scope. As soon as the trailing edge of the sun contacts the vertical crosshair, either tap the Get Local Time button or use an external timepiece and note the precise time.
User’s Manual – Conventional Mode What to Do Next With the azimuth to the backsight known, you can now perform the following steps to begin your survey. 1. Without moving from the occupy point used while performing the solar observation, note the computed average azimuth from the Solar Observation Results screen. 2. From the Main Menu, access the .Survey , Backsight Setup screen. 3. Toggle the BS Point / BS Direction button to BS Direction and enter the computed azimuth in that field.
Other Tutorials Remote Control Remote control mode is a special mode that makes it possible for users to control a fully robotic total station from a remote data collector. Remote control mode contains additional screens that are used exclusively with robotic instruments that perform tracking and aiming functions. The behavior of the software differs slightly in remote mode when a shot is taken and when performing stake out.
User’s Manual – Conventional Mode Once the total station is aiming near the prism, the Search button is used to start the total station in a search pattern. The search pattern continues until it finds the prism. The Lock button puts the total station in track mode where it will track the movements of the prism and Stop will stop the total station from tracking the prism. Tapping the Aim tab will open a screen used to precisely aim the instrument.
Other Tutorials Taking a Shot in Remote Mode When running in a non-remote mode, tapping the Traverse or Side Shot button will simply trigger the total station to take a shot. When running in remote mode, tapping these buttons will open the Remote Shot screen. The Remote Shot screen is nearly identical to the Remote Control screen except it has an additional button that allows you to trigger the total station to take a shot.
User’s Manual – Conventional Mode Stake Out in Remote Mode Performing stake out in remote mode is different from running in a non-remote mode because the feedback is continuous and provided in the rod’s point of view instead of the total station’s. Stakeout data is presented in the Remote Staking screen. All of the information is displayed as if the rod person were facing the total station. The graphic portion of the screen will change depending on how close the rod is to the stake point.
Other Tutorials Remote staking beyond 10 feet from target Remote staking between 1 and 10 feet Remote staking within 1 foot from target Remote staking over target 151
User’s Manual – Conventional Mode Slope Staking in Remote Mode Slope staking in remote control mode functions in nearly the same way as with a non-remote total station (see Page 156). The one difference is when using the final Slope Staking screen, where the catch point is being located, the graphic portion of the Horizontal Map and Vertical Map is updated continuously.
Other Tutorials GeoLock GeoLock is a feature that uses a GPS receiver to calculate your position so while working robotically, if the total station loses lock of the prism, it can quickly turn to the location of the prism based on the GPS position and then automatically perform a search to lock back onto the prism. GeoLock is available when using a Trimble or Geodimeter robotic total station, along with a GPS receiver that outputs a NMEA signal.
User’s Manual – Conventional Mode Configuring GeoLock Once you have setup your job and total station, you need to power on your GPS receiver and establish communication. 1. Attach the communications cable, if applicable. 2. Open the Remote Control or Remote Shot screen. 3. Set your EDM mode to Track. This is important for the localization process, explained later. 4. Tap the satellite icon in the Command Bar to open a list of GeoLock options. 5.
Other Tutorials 9. Tap to save the settings and close the screen. You are now ready to collect data and start the localizing process. If the satellite icon is now red in color , tap the icon and read the bottom line of the list that opens to see what the problem is. If the message says No GPS Data, check your communication connection between the data collector and GPS receiver. If the message says GeoLock Requires Backsight set, you need to solve your backsight or no localization solution can be calculated.
User’s Manual – Conventional Mode back to yellow and you will need to move around again to relocalize before you can use the GeoLock feature. Using GeoLock If, for example, you have a localization solution and you pass behind a group of trees where the total station loses lock on the prism, the GeoLock button will become enabled.
Other Tutorials The Slope Stake routine can automatically determine if the outer slope of the road profile should have a positive or a negative slope based on the location of the hinge point. If Terrain the hinge point is located below the surface of the terrain, Hinge Points a positive slope is selected and a cut will be required, Catch Points starting at the catch point.
User’s Manual – Conventional Mode 5. Enter the horizontal width of the left and right sides of the road in the 1/2 Road Width fields. These widths do not have to be the same. 6. Enter the cross-slopes of each side of the road in the X-Slope (%) fields. Note: A negative X-Slope value will result in a slope where water runs from the centerline of the road toward the edge. 7. If the road profile also includes a curb or a ditch, check the Stake Curb / Ditch checkbox and define the curb or ditch as follows. 8.
Other Tutorials Ditch CL 14. The Segment # (Fill HP) field is used to select which segment to compute the slope from in a fill situation. This is useful when your road profile includes a ditch and you Catch Point Hinge Point (Segment 2) are staking an area that requires a fill. In this situation, A road with a ditch requiring the ditch would not be necessary so you have the option to a fill and the hinge point is at compute the slope from Segment 1. (See illustration.)

Leveling Fieldwork Leveling is one of three possible surveying modes that can be used with Survey Pro. Leveling mode in Survey Pro can only be used after purchasing and registering the Leveling Module. (See Page 4 for more information on registering modules.) Once registered, level loops and the 2 peg test can be performed. Leveling data collection is organized into loops. A level loop is a series of level measurements that start with a backsight on a known point with a valid elevation.
User’s Manual – Leveling Mode Benchmark: A point in a level loop that is stored in the current job. Benchmark points are usually permanent marks on the ground that can be reoccupied at a later date. Benchmarks are part of the level loop since they are used as the backsight for the next setup, with the exception of the closing benchmark. Leveling Side Shots: An intermediate shot from any setup in the level loop.
Leveling Level Settings The Level Settings screen is where the shooting sequence and leveling tolerances are configured. Fill in the screen as necessary. If any shots exceed the tolerance specified and the corresponding checkbox is checked, a prompt will appear to warn you. Consult the Reference Manual for more information on the individual fields in this screen. The Load FGCS Defaults button will open the FGCS Defaults screen where you can specify a particular order and class for the level loop.
User’s Manual – Leveling Mode Leveling Methods Survey Pro supports the following leveling methods: • Three Wire • Single Wire • Electronic • Trigonometric All of the leveling methods can be performed in Manual Mode, where the readings are read from an instrument and then manually keyed into the data collector.
Leveling Manual Leveling If you will be entering data manually, select and activate the Manual Mode and tap Activate to activate it and then tap Instrument Settings to open the Level Method screen. Select the manual leveling method you want to use and tap . Level Loop Procedure The procedure for leveling with Survey Pro is nearly identical no matter which method you are using. The main difference for each method is the type of information that is entered with each shot taken.
User’s Manual – Leveling Mode Creating a New Loop 1. From the Main Menu, select Leveling > Select/Create Loop . This will open the Select/Create Loop screen. You can select an existing loop that has not yet been closed, or create a new loop. Selecting a closed loop will display detailed information about that loop. 2. Tap the New Loop > button. The New Level Loop screen will open. 3. Enter a name for the new loop in the New Loop field and enter your starting benchmark in the CBM field.
Leveling 4. The details of the new loop are displayed on this screen. You can optionally enter a description for the new loop and then tap Create Loop to create and open the new loop. 5. A prompt will tell you that the new loop has been created. Tap OK and you will automatically be taken to the Level screen where you can begin collecting data.
User’s Manual – Leveling Mode Level Screen 6. This is called the Level screen, although the title bar displays the name of the current level loop. The Level screen will automatically open after a new loop is created, or if an existing loop (that has not yet been closed) is selected. It can also be accessed manually from the Main Menu by selecting Leveling > Level . The Level screen is used to indicate which type of shot you want to take next.
Leveling Turn to Turning Point (Leveling Shots) 7. When shooting a turning point, you will immediately be prompted for the necessary shots for all sets in the sequence selected in the Level Settings screen (Page 191). This screen is also used when performing the actual shots for all the other types of shots that can be selected from the Level screen.
User’s Manual – Leveling Mode 198 Three Wire Shot Single Wire Shot Electronic Shot Trigonometric Shot
Leveling 9. Once all the shots in the sequence are completed, the Shot Results screen will open listing the details for each point. You can remove the backsight and/or foresight shot with the worst residual by tapping the corresponding Toss button. The shots with the worst residuals are always removed first. Continuing to tap the button will eventually remove all the shots taken to that point.
User’s Manual – Leveling Mode Turn to Benchmark 11. This option should be used whenever you will be shooting any benchmark other than the starting benchmark. (The starting benchmark is always the backsight for the first shot in a level loop.) Enter the benchmark point in the BM Point field. If this is a closing benchmark, this point must already exist in the current job.
Leveling If you are not closing your level loop, you will return to the Level screen in Step 6. If you are closing your level loop, continue to the next step. 15. The Close Loop screen will open and display all the information about the loop. If you tap Close Level Loop , the loop will be closed and no more shots for that loop can be taken. You will then return to the Level screen and all the shot buttons will be grayed out. Note: Once a level loop is closed, no additional shot data can be added to it. 16.
User’s Manual – Leveling Mode 17. While viewing the notes for any level loop, you can tap the (Settings) button to customize the settings for this screen. (This is the only location where you can access this Settings screen.) For more information on each field of this screen, consult the reference manual.
Leveling Side Shots 18. Prior to shooting a benchmark or turning point, you can shoot any number of leveling side shots to compute the elevation for any arbitrary points. Enter the point name in the SS Point field, and an optional description in the Desc field. Since the horizontal coordinates for the new point cannot be computed from the leveling routine, you must provide them manually in the N and E fields.
User’s Manual – Leveling Mode Stakeout 19. Shooting a leveling stakeout point is similar to a leveling side shot in that it must be done before shooting a benchmark or turning point from any particular setup, and once complete, you will return to the Level screen where the next shot type is selected, without advancing to the next setup.
Leveling 2 Peg Test The 2 Peg Test is used to check the collimation error of the instrument. The test will compute the error, which can then be used to adjust the horizontal crosshair of the instrument. 1. Position two rods 50 to 90 meters apart (165 to 300 feet). 2. Pace off the distance between the rods and set up the level midway between them. (The placement of the rod over Point B can be adjusted after shooting Point A.) 3. Carefully level the instrument.
User’s Manual – Leveling Mode 7. You can optionally tap Check H. Dist to verify the instrument is centered between the two rods. The distance to Point B will be measured and compared to the horizontal distances previously measured to Point A and a come/go distance will be provided so the rod at Point B can be moved to equal the horizontal distance to Point A prior to taking the shots that will be used to compute the error. 8. Tap Take Shot.
Leveling 12. After the final shot is taken, the Peg Test Results screen will open showing the details of the shots taken and the computed error.
GPS Overview This portion of the User's Manual includes basic fundamentals of GPS coordinate systems and measurements. The following section discusses how GPS coordinates are used in Survey Pro. Both of these sections contain general information that applies to both the GPS module and Basic GPS module. Following these general sections are two sections that are specific for the GPS module and the Basic GPS module.
User’s Manual – GPS Mode ¾ A description of using Ground Coordinates on a reference mapping plane. ¾ A description of geoid modeling and how to use geoid models for vertical transformations. RTK and Post Processing Using GPS for precise survey measurements requires data from two receivers to be collected simultaneously. There are two common methods for calculating positions with this data: Real Time Kinematic (RTK) and post processing.
GPS Overview GPS Measurements GPS coordinates are computed using pseudo-range positioning. Pseudo-range positioning involves intersecting the ranges from the known SV position in a manner similar to a distance – distance intersection problem. Four SVs are required to determine three position dimensions and time. Position dimensions are computed by the receiver in Earth-Centered, Earth-Fixed X, Y, Z (ECEF XYZ) coordinates. A pseudo-range solution will be one of two types: autonomous, or differential.
User’s Manual – GPS Mode Code Differential Code differential solutions use the Coarse Acquisition (C/A) navigation code transmitted on the GPS carrier wave. Because the wavelength of the code segment is long (300m), code differential is the least precise differential solution. Accuracies of 1-10 meters are possible with DGPS using C/A code differential positioning. Carrier Phase Differential Highly precise coordinate differences can be measured using pseudorange positioning with the carrier signal wave.
GPS Overview GPS Network Servers, NTRIP, and VRS Traditionally, RTK GPS was done with a base and rover receiver setup on the survey site and using a radio data modem to get the observations from the base to the rover for the real time solution. Another way to do RTK GPS is to use one or more permanently operating base stations connected to an Internet network.
User’s Manual – GPS Mode these corrections, such as Trimble VRS. A detailed description of these technologies is beyond the scope of this manual. Please see the end of this manual for references to more information. Network Transfer of RTCM via Internet Protocol (NTRIP) The Network Transfer of RTCM via Internet Protocol (NTRIP) is a standard established by the Radio Technical Commission for Maritime Services (RTCM).
GPS Coordinates To represent positions in space you need two things. First, you need a datum to define an origin, an orientation, and a scale. Second, you need a coordinate system to specify the locations in the datum. GPS positions are in a global geocentric datum, using latitude and longitude angles to specify location. Most engineering and surveying jobs require positions in a 2D Cartesian coordinate system.
User’s Manual – GPS Mode WGS84 Geodetic v. Local Geodetic When the coordinate system is a mapping plane in a datum other than WGS84, positions measured in WGS84 latitude, longitude and height, must be transformed into local latitude, longitude, and height before they can be used to calculate northing and easting with the specified map projection. There are three methods of datum transformation supported by Survey Pro. • Molodensky Transformation: Is the most commonly used transformation.
GPS Overview Horizontal Datums • NAD27 The North American Datum of 1927 (NAD27) horizontal datum was established in the early part of the twentieth century to define a horizontal coordinate system in North America. The datum originated at a central point, Meades Ranch in Kansas. From there, conventional triangulation and trilateration networks radiated outward to establish new monuments in the system.
User’s Manual – GPS Mode (1996.0). The date in the brackets indicates the epoch defining the datum. This is all quite confusing. Fortunately, for most RTK GPS applications, you do not need to worry about these WGS84 differences. The significant part of the datum difference is a shift, and you correct this when you specify the GPS base position. The other part of the datum difference is the small rotation of the axes.
GPS Overview apples and oranges. For example, if you set your base on a point with a known coordinate in the NAD83(1996.0) datum, then all the rover positions will be in the NAD83(1996.0) datum. Similarly, if you set the base on an autonomous position, and occupy one or more NGS control monuments all in the NAD83(1999.0) datum, then the localization corrects your entire survey to the NAD83(1999.0) datum.
User’s Manual – GPS Mode datum not programmed into the database, you can use the Projection Key In Wizard to create a custom Molodensky or similarity datum transformation. Vertical Datums GPS satellites orbit the Earth’s center of mass, while objects on the surface of the planet are affected by the force of the local gravity field.
GPS Overview then run across the country and closed on the opposite coast. This datum contained a number of systematic errors including un-modeled local gravity effects and refraction errors. Also, it was later discovered that the “mean sea level” from the Atlantic to the Pacific Oceans was not the same. • NAVD88 In an effort to address these errors, the North American Vertical Datum of 1988 (NAVD88) was realized from a single datum point in Rimouski, Quebec.
User’s Manual – GPS Mode apply. When a vertical coordinate is required, most survey projects require orthometric elevations. Z h Gr ee • Lat, Lng, Ht Geodetic horizontal coordinates are usually expressed as two angles called latitude and longitude (φ, λ). Geodetic vertical coordinates are usually expressed as the distance above the ellipsoid called height. The angles describe a point’s position on the surface of the reference ellipsoid.
GPS Overview Horizontal Coordinate Systems Survey projects use horizontal coordinates on either a local plane or a map projection. For small projects, you can assume a simple flat earth plane and calculate coordinates directly with measured distances. Use Ground - TDS Localization mode for this procedure. For large projects, a mapping plane is used to accurately represent the curved surface of the earth on a flat plane and conventionally measured distances need to be scaled to the mapping plane grid.
User’s Manual – GPS Mode • Area A map projection is equi-areal when it correctly plots areas over the entire map. That is, all mapped areas have the same proportional relationship to the areas on the Earth that they represent. Common Conformal Map Projections in Surveying • Transverse Mercator The Transverse Mercator (TM) projection results from projecting the ellipsoid onto a cylinder tangent to a central meridian.
GPS Overview • Stereographic The Stereographic projection results from projecting an ellipsoid onto a plane. Directions are true from the center point and distortions in scale, area and shape increase uniformly away from the central point. The stereographic projection is azimuthal. Because the scale is distorted somewhat uniformly in all directions, stereographic map projections are a good representation of a surveyor’s typical flat earth ground coordinate system.

GPS Overview Distance on Ground Ellipsoid Height, h Distance on Ellipsoid R+h Radius of Ellipsoid, R Fig. 5: Ellipsoid Scale Factor The effect of height above the ellipsoid on scale. Ellipsoid Scale Factor This scale factor accounts for the height of the ground above the reference surface (the ellipsoid).
User’s Manual – GPS Mode Vertical Coordinate Systems GPS measurements provide ellipsoid heights. Most survey projects require orthometric elevations. To convert heights into elevations, you need to correct for the difference between the surface of the reference ellipsoid and the level surface representing the gravity field. The procedure to convert heights (h) to elevations (H) involves the use of a geoid model. The geoid is a theoretical surface that approximates mean sea level.
GPS Overview • In Canada you can use the Geodetic Survey Division HT 2.0 model, or the older GSD95, HT1_01, and HT97 models. • For any location world wide, you can use the NIMA 15-minute geoid height grid data file, WW15mGH.*. This file covers the entire globe on a 15’ x 15’ grid. In Australia you can use the AUSGEOID98 geoid model. Note: To use any of these geoids with Survey Pro, you need files in Trimble .ggf format.
GPS Coordinates In Survey Pro GPS positions are measured in a 3D coordinate system which models the earth using an ellipsoidal shape. The horizontal position is usually given as two angles, relative to the ellipsoid axes, called latitude and longitude. The vertical position is usually given as a linear distance, perpendicular to the ellipsoid, called height. Most survey projects use horizontal coordinates on a plane which approximates a small piece of the ground assuming a ‘flat earth’.
User’s Manual – GPS Mode Projection Mode Survey Pro has two different modes for calculating local northing and easting from GPS measurements: Ground – TDS Localization, and Mapping Plane. In Ground - TDS Localization mode, the is no map projection and no datum to transform geodetic to local coordinates. In this case, a default map projection is created with the first RTK base setup. Then, a localization adjustment is solved (Page 270).
GPS Coordinates in Survey Pro Projection Mode Summary Horizontal Projection Modes Ground - TDS Localization Local coordinates are at ground level, based on the project height. Distances shot with EDM are at ground scale, so are 1:1 with coordinates solved by the projection. Default map projection and datum are automatically initialized with RTK base setup. Mapping Plane Local coordinates are on a conformal map projection grid.
User’s Manual – GPS Mode A coordinate system is un-initialized when you have no zone record set. In Ground – TDS Localization mode, this means that you have not yet configured the first RTK base position in Survey Pro. In Mapping Plane mode, this means you have not yet selected a zone record from the coordinate system database. A coordinate system is set when there is a zone record set.
GPS Coordinates in Survey Pro coordinates to your mapping plane coordinates. Therefore, a localization is not required in this case. • If your job already contains geodetic coordinates which were measured from an autonomous setup, and you are continuing the survey using coordinates from the network GPS, you will need to resolve the localization to get results in the proper local system. This is the case for both Ground – TDS Localization and Mapping Plane horizontal projection mode.

GPS Module Start GPS Survey - Solve Localization The Start GPS Survey Solve Localization screen is displayed when you need a horizontal adjustment to solve your coordinate system. A horizontal adjustment is required to solve your coordinate system any time you begin a survey from an autonomous base position. This is always the case when your projection mode is Ground – TDS Localization, since your first base setup is always from an autonomous GPS position.
User’s Manual – GPS Mode Solve Localization When you start a GPS survey from an autonomous base position, you need to solve a localization to adjust GPS measurements into local coordinates. This is the case for both horizontal projection modes. Using Ground - TDS Localization, you need to solve a localization to relate your arbitrary GPS start point into your non-geodetic local system.
GPS Module Localization with Control Points Horizontal localization is a simple 2D similarity transformation from mapping plane coordinates in an intermediate system to coordinates in your local system. In Ground - TDS Localization mode, the intermediate system is the default map projection initialized for ground distances at the base height. In Mapping Plane mode, the intermediate system is the inaccurate coordinates calculated on the selected map projection from the autonomous GPS base.
User’s Manual – GPS Mode Detailed Procedure Since the field procedure is the same for both horizontal and vertical localization solutions, the instructions below cover both cases. 1. From the Control Points screen, select a control point to occupy and enter the name into the Point control. Horizontal control points must have a valid northing and easting coordinate in the local system.
GPS Module 7. In the list box, control points collected will be identified with an H and/or V. Points marked H will be used to solve horizontal localization. Points marked with a V will be used to solve vertical localization. You can select or deselect any point by highlighting that point and then: tap the H and/or V column beside that point; press H and/or V on the keyboard. Note: If your base was set up on a known point, that point is an eligible control point.
User’s Manual – GPS Mode • Unique: the solution was calculated using the minimum number of control points or fewer. In this case, there is no least squares solution to provide residuals, so the numbers in the N Err, E Err, and/or V Err columns are misclosures calculated from the control points that are not used in the solution. • LSQ: the solution was calculated with more than the minimum number of control points.
GPS Module 14. When you are happy with the solution, tap Accept to set the horizontal and/or vertical adjustment. The Adjust with Projection wizard will open to show you a preview of the changes to the geodetic points. Tap Accept to update the coordinate system in the job and raw data, and to apply the adjustment to the points. Manual Entry of Parameters Manual entry of parameters is used when you already know the appropriate horizontal and vertical localization parameters for a site.
User’s Manual – GPS Mode Localization Parameters Explained Before you accept a localization solution, you should evaluate the parameters and the quality of the solution. This section describes the meaning and the expected values for the six horizontal and five vertical localization parameters. Guidelines for the quality and geometry of control points plus the solution redundancy and residuals are also described.
GPS Module Mapping Plane Mode: Scale: is the scale difference between the intermediate mapping plane using the autonomous GPS position and the actual mapping plane control coordinates. Scale should be very close to 1.0. A value of 1.0 corresponds to grid distances on the selected conformal mapping plane. A scale value significantly greater or smaller than 1.0 may indicate problems with the control point accuracy and/or the control measurement precision.
User’s Manual – GPS Mode Vertical: Slope: is the North and East tilt of the inclined plane adjustment. These values are given in parts per million, and represent the radian angle values of the deflection between the ellipsoid normal and the local gravity vector. This tilt approximates what a geodosist would call 'deflection of the vertical'.
GPS Module Quality of Localization Solutions Starting from an autonomous GPS base position and solving a localization with control points is similar to starting a conventional survey from an unknown setup and solving a resection. The quality of the solution depends on both the precision of the measurements to the control points and the accuracy of the control point coordinates.
User’s Manual – GPS Mode • Check points: after solving for localization parameters with a minimum number of control points, you should occupy an independent checkpoint to verify the solution quality. If you desire, this point can be added as a control point and used for subsequent solutions. If the checkpoint measurement is within the tolerance, this step should not be necessary.
GPS Module the local coordinate system, it is not possible to compare the geodetic coordinates from the different sets of data. Survey Pro solves this problem by assigning a set up group each time a new autonomous base is set. A set up group is a unique flag attached to each point record generated by GPS. Setup groups are assigned as follows: • When you set a new base point with an autonomous GET, Survey Pro creates a new set up group for this point.
User’s Manual – GPS Mode • The coordinate system has its origin at the local northing and easting of the first base position. The localization Translation values would be the offset between the default map projection’s origin (100000, 100000)m and the local coordinate of the base. Localization Calculator Note: The Localization calculator is used to provide the field procedure for a workflow supported in Survey Pro versions prior to 3.5.

GPS Module Import GPS Control In some cases, you can occupy a GPS control point in the field during data collection, but you do not have the correct mapping plane local north, east, elevation coordinate for that control point. In this case, you can not solve the localization in the field. However, it is possible to solve the localization after the field work has been completed, and Survey Pro will update all of the GPS collected points with the proper local coordinate.
User’s Manual – GPS Mode • You start a survey with your base on an autonomous position. You occupy one or more control points during the survey, but you do not have the proper north, east, elevation coordinate in the field.
