Noggin 11-Locate & Mark Mode 11.4.2 Clear Image Deletes the current data image on the display. 11.4.3 Color GPR images are displayed in colors corresponding to a color palette. In general, stronger GPR signals appear in stronger colors. A number of different color palettes are available to display the image. Some color palettes may show the target better than others.
11-Locate & Mark Mode Noggin 11.4.4 Gain Since GPR signals are absorbed by the material being scanned, deeper targets have weaker signals. Gain acts like an audio volume control, amplifying the signals and making deeper targets appear stronger in the image. The Gain varies from 1 to 9 with 1 being no gain and 9 being the maximum gain. As the Gain changes, the current image on the display updates so it is not necessary to re-collect an image with a different gain setting.
Noggin 11-Locate & Mark Mode 11.4.5 Filter The filter has the effect of removing flat-lying reflections in the image and enhancing the dipping reflections and arches usually caused by targets. It can also assist in identifying very shallow targets that might be masked by the strong signals at the top of the image. The Filter defaults to ON, so if you are looking for a layer or other flat-lying target, turn the Filter OFF. The image below shows the same scan with the Filter OFF and ON.
11-Locate & Mark Mode Noggin 11.4.6 Depth The depth setting is an estimate of the total depth displayed on the Scanning Screen based on the current Soil Type setting. The depth setting ranges from 1 to 8 meters. The system always collects data to a depth of approximately 8 meters but the Depth setting on this menu determines how much of the data is displayed on the screen.
Noggin 11-Locate & Mark Mode 11.5 Changing the Date and Time From the System Settings Screen, select the Date option. The Time option is similar. Use the Left and Right Arrow buttons to highlight the number to change in red. Increase the number using the Up Arrow and decrease the number using the Down Arrow. Pressing OK saves the new date or time and exits the screen. Pressing Cancel exits the screen without saving the date or time.

Noggin 12-Survey & Map Mode 12 Survey & Map Mode The Survey & Map main menu has the following choices: 12.1 Survey & Map Menu 12.1.1 Line Survey lines collected with the Noggin are saved as digital data files that can be viewed on the DVL or exported to an external computer for processing and plotting. Sensors & Software programs like EKKO_View, EKKO_Mapper and EKKO_3D are available to process and display the data. Pressing the A button from the main Noggin menu takes the user to Line data collection.
12-Survey & Map Mode Noggin Grid collection involves collecting data in an organized pattern over an area. This type of data acquisition allows the GPR data to be presented as plan maps with the EKKO_Mapper software or 3D volumes with the EKKO_Mapper 3D software. For inexperienced surveyors, laying out a grid with straight lines and all the corners at 90 degree angles can be difficult. Sensors & Software provides a product called EasyGrid to make laying out an accurate grid simple.
Noggin 12-Survey & Map Mode e) Determine how much space is left on the DVL (see Section 12.5.5: P.111). f) For the optional PXFER cable used to transfer data from the DVL to a PC, set the PXFER Transfer Mode to Normal or Turbo (see Section 12.5.6: p.111) 12.1.7 Set Storage Drive This setting controls how data are saved on the DVL. The available options are: 1) Internal: If this setting is selected, the data are saved to the internal compact flash drive in the DVL.

Noggin 12-Survey & Map Mode 12.2.2 Screen Overview The data acquisition screen is shown in Figure 12-1. It is divided into 3 sections. Figure: 12-1 Noggin Data Acquisition Screen The Noggin screen is shown in Figure 12-1. It is divided into 3 sections. The top section provides positioning information. The center section contains the actual data and the bottom section contains the menu. 12.2.
-Survey & Map Mode Noggin 12.2.4 Data Display This section contains the actual data collected or replayed. The section also contains the Depth Lines and any Fiducial Markers the user enters. See the sections below for more details. 12.2.4.1 Depth Lines Depth lines are horizontal lines indicating the estimated depth. They are very useful for getting depth estimates to features of interest in the data. The Depth Lines are controlled by the current velocity value as well as the depth selected.

If a GPS receiver is attached to the DVL (see Section 12.3.5: P.103) a message will appear in the bottom left corner of the menu indicating whether the GPS data is successfully being logged.
12-Survey & Map Mode Noggin Figure: 12-2 Effects of the Gain setting Note that the gain setting is only for data display. The data are always saved without any gain applied. It is not possible to collect Noggin data with an “incorrect” gain setting. If the user finds that they are always using very high or very low gain settings to see the data adequately, the user may want to adjust the Linear Gain setting under Setup (see Linear Time Gain on page 88). 12.2.
Noggin 12-Survey & Map Mode The odometer should be periodically re-calibrated to ensure accuracy. The procedure for recalibrating the odometer is described in Section 12.5.2: P.110. 12.2.7.1 Reducing Data Quality by Moving too Fast On the lower part of the data acquisition screen, beside the current total number of traces collected is the total number of traces skipped.
12-Survey & Map Mode Noggin When the Smart System is used in Free Run mode, it is up to the user to keep track of positioning by some other method, for example, a measuring tape, using fiducial markers (see Fiducial Markers on page 72) or GPS (see Section 12.3.5: P.103). In this mode, data collection is dependent on two factors, 1) the speed that the Noggin system is collecting data and 2) the speed the Noggin system is moving. 12.2.8.
Noggin 12-Survey & Map Mode In Trigger Button mode, the system “beeps” as each trace is collected. The length of the beep will depend on the number of stacks (the more stacks, the longer it takes to collect a trace and therefore the longer the beep). When the Smart System is used in Trigger Button Mode, it is up to the user to keep track of positioning by some other method, for example, using a measuring tape, fiducial markers (see Fiducial Markers on page 72) or GPS (see Section 12.3.5: P.103).
12-Survey & Map Mode Noggin To see how much data can be collected before the DVL memory is full and data must be deleted or downloaded, see DVL Recording Space in Section 12.5.5: P.111.
Noggin 12-Survey & Map Mode 12.2.11 Calib. (Calibration) Menu Noggin systems can be used to scan into many different materials including soil, rock, concrete, snow, ice and wood. The radio wave emitted by a Noggin system will travel at different velocities depending on the material being scanned. The depth value (see Section 12.3.1: P.84) and on Depth Lines (see Section 12.2.4: P.72) are only accurate if the system has been properly calibrated to determine the velocity of the material being scanned.
12-Survey & Map Mode Noggin With the hyperbola visible on the DVL screen, select the hyperbola (∩) button. This will superimpose a hyperbola on the data. This hyperbola can be moved up (!), down ("), left (#) and right ($) using the appropriate arrow buttons. The goal is move the hyperbola until it lies on top of the hyperbola in the data (see Figure 12-4).
Noggin 12-Survey & Map Mode 12.2.11.2Identifying Air Reflections Some hyperbolic reflections can also be caused by objects not in the subsurface such as fences, overhead wires and, in some conditions, even large trees. An important part of data interpretation is learning to recognize these unwanted “air” events and differentiate them from the desired subsurface events. Good field notes are indispensable for helping identify unwanted events on the data.
12-Survey & Map Mode Noggin 12.2.11.3Target of Known Depth If there are no suitable hyperbolas visible in the data to perform the Hyperbola Matching described above, it may be the situation that there is a target of known depth in the area being scanned. If this is the case, selecting the button with the circle with a horizontal line through it will superimpose a horizontal line on the data. This line can then be moved up or down until it lies on top of the Noggin response to the known target.
Noggin 12-Survey & Map Mode 12.2.12 Error Messages If an error occurs during data acquisition, an error message will appear in the bottom left section of the data acquisition screen. Note the message number, exit the program and turn off the Digital Video Logger. Make sure the cables are not damaged and that all cable connections are tightly secured. Sometimes vibrations cause the cable connections to loosen just a bit and break contact and this can cause errors.
12-Survey & Map Mode Noggin 12.3 Noggin Setup Pressing the number 1 on the main menu selects the Setup item. Setup lists the various parameters that can be edited. These parameters are organized under the following headings: 1 - System Parameters 2 - Cart Parameters 3 - Line Parameters 4 - Grid Parameters 5 – GPS Parameters 6 – Set Defaults To select a setting to edit, press the corresponding number button. Then use the numbered buttons to select the new setting.
Noggin 12-Survey & Map Mode 12.3.1.2 Velocity The wave velocity depends on the properties of the material. The Noggin software allows the user to input a velocity, which changes the total time window collected by the system. See Section 12.2.11: P.79 for a discussion about determining velocity. A table of typical radar velocities in various materials is given below. If in doubt, use a value of 0.10 m/ns. This is a good average velocity that will provide a good estimate of depth in most situations.
12-Survey & Map Mode Noggin 3) Noggin 500 4) Noggin 1000 12.3.1.5 Stacks Some materials tend to absorb radar signals and limit penetration. These materials are said to be lossy. When collecting data in lossy areas or areas with a lot of radio frequency noise, one way of increasing data quality is to collect more than one trace at each survey position, average them and save the averaged trace. This is known as “stacking”.
Noggin 12-Survey & Map Mode DynaQ is an advanced, patented technology that dynamically adjusts stacking as the system movement speed varies. In most situations, moving the system at a comfortable speed stacks enough to generate data of good quality. In situations where target resolution or maximum penetration depth is critical, moving slower increases the number of stacks and increases the data quality.
12-Survey & Map Mode Noggin 12.3.1.6 Linear Time Gain As described in Section 12.2.6: P.73, the weak signals must be amplified or “gained” to see them on the display. The Gain button described in Section 12.2.6: P.73 can be set to a value from 1 to 9 depending on the amount of gain required (1 is lowest gain, 9 is highest gain). There is also a second level of gain available to the user and that is the Linear Gain setting. The default Linear Gain setting of 2.
Noggin 12-Survey & Map Mode 12.3.2 Cart Parameters The Cart Parameters settings allow the user to view and modify settings specific to the Smart System. This includes the direction the Noggin will move to collect data, whether or not the odometer is active and whether Auto Start is on or off. 12.3.2.1 Cart Direction This setting determines whether data are collected as the Noggin is pushed forward or pulled in reverse. The back up arrow (see Section 12.2.7: P.
12-Survey & Map Mode Noggin After the user selects this option, a menu appears to select the number of stacks for each trace (for more details on Stacking, see Stacks on page 86). Note that when data are collected in Trigger Button mode, the Smart System will emit a beeping sound after the button is pressed to indicate data collection is taking place. 12.3.2.
Noggin 12-Survey & Map Mode For standard Smart Systems the Transfer Rate value must be set to 8. The Transfer Rate value will only be decreased for systems with data cables longer than standard lengths. Please contact Sensors & Software before changing the Transfer Rate on your system. 12.3.2.7 Odometer Number Noggin Smart Systems can take input from several different odometers. It is very important that the user selects and calibrates the odometer appropriate for their Smart System.
12-Survey & Map Mode Noggin 12.3.3 Line Parameters The Line Parameters settings allow the user to view and modify settings specific to collecting data as individual lines, namely, the starting position of the line and line direction. 12.3.3.1 Start Position The Start Position is the position value at the very beginning of a line. This will usually be set to zero (0.0). However, if the user wants a data file to start at a position other than zero, this value can be edited. 12.3.3.
Noggin 12-Survey & Map Mode 12.3.3.3 Station Interval As Smart Systems moves, the odometer triggers the system to collect a data trace at fixed distance intervals. This interval is called the “station interval”. The station interval can be changed to allow a longer or shorter distance between traces. For a successful survey, it is important that several traces be collected over a target.
12-Survey & Map Mode Noggin The choices available are: 1) 2) 3) 4) 5) 6) 7) 8) 9) Short Normal Long X-Long 10x Normal 20x Normal 40x Normal 50x Normal 100x Normal Each choice listed will be followed by an actual value in metres or inches depending on which units are selected and which Noggin system is being used. Here is a chart showing the station interval for each system and setting.

12-Survey & Map Mode Noggin 12.3.3.4 Plot Interval The plot interval setting determines the width of data traces plotted to the screen. Traces can be 1, 2, 4 or 8 pixels wide. The Normal setting for Noggin 250 systems is 2 pixels per trace and the Normal setting the Noggin 500 and 1000 is 1 pixel per trace. It can be useful to plot traces narrower than normal to allow more data to fit onto one screen. It can also be useful to plot traces wider on the screen so that they are easier to see.
Noggin 12-Survey & Map Mode 12.3.4 Grid Parameters The Grid Parameters settings allow the user to view and modify settings specific to collecting data in organized grids. This includes the grid dimensions, line spacing, grid type and survey format. Data are normally collected on a grid if the user is interested in displaying the data as a 3D volume (using the EKKO_3D software) or as a plan map (using the EKKO_Mapper and/or EKKO_Pointer software).
12-Survey & Map Mode Noggin Y Lines Only - Forward Set up a first-quadrant XY grid. Data lines run in the Y direction, distance increasing from the X axis baseline. Line numbers increase in the positive X direction (see Figure 12-12). Lines must be equally spaced. It is not critical that all the lines are the same length. However, it does make processing easier if all the lines start at the same baseline position (usually defined as zero (0.0)). Figure: 12-12 Proper Y Line surveying pattern.
Noggin 12-Survey & Map Mode 12.3.4.2 Survey Format The Survey Format specifies how the lines will be collected. The lines shown in Figure 12-11, Figure 12-12, and Figure 12-13 are all collected in the Forward direction only. This means that each line starts at the X or Y baseline. When the length of the survey lines are more than about 20 metres, data acquisition speed may be increased by collecting every second line in the reverse direction (Figure 12-14, Figure 12-15, and Figure 12-16).
12-Survey & Map Mode Noggin Figure: 12-15 For collecting GPR data consisting of long data lines it makes more sense to follow a forward and reverse surveying pattern. For the final data to be spatially correct with a minimum of editing, data collected in this pattern should be on lines that extend completely from one baseline to the other. XY Lines – Forward and Reverse Using the Forward and Reverse survey format, XY line data are collected in the pattern shown in Figure 12-16.
Noggin 12-Survey & Map Mode 12.3.4.3 Grid Dimensions For grid data acquisition, the grid size needs to be specified. The user needs to input the length of the X dimension and the length of the Y dimension. The dimensions entered are assumed to be in the same units as the Position Units (see Section 12.3.1.7: P.88), i.e. metres or feet. On this screen the user needs to highlight the dimension to be changed. The user can toggle between the X and Y fields by pressing the X/Y button.
12-Survey & Map Mode Noggin However, line spacing should really be determined by target size. In most cases the system must pass over a target to detect it. Therefore, the line spacing needs to be on the order of the size of the target or smaller, if practical. This can be adjusted to a larger spacing for larger targets or targets with a linear extent. As well, these rules may have to be bent for practical purposes like survey production rates.
Noggin 12-Survey & Map Mode 12.3.5 GPS Parameters The Global Positioning System (GPS) uses special satellites around the Earth to determine the position of a GPS receiver located at any position on the surface of the Earth. GPS receivers can be purchased from a number of manufacturers. The DVL has a serial port on the back for attaching a GPS receiver. This port will accommodate any GPS receiver that has a standard serial port output.
12-Survey & Map Mode Noggin Mode There are three GPS modes available: 1) Off mode means that a GPS receiver is not connected to the DVL so no GPS information is being logged. This should be the setting if you do not have a GPS receiver. 2) Reading every x traces mode means that every time the Noggin collects a userdefined number of traces of GPR data, a data string of GPS information will be added to a file. This file has the same name as the data file i.e. LINE6, but with a GPS extension.
Noggin 12-Survey & Map Mode 3) Fuducial Tagging mode means that whenever a fiducial marker (F1, F2 etc.) is added to the data (see Section 12.2.4: P.72), a data string of GPS information will be added to a file. This file has the same name as the data file i.e. LINE6, but with a GPS extension. This file can be accessed after transferring the GPR data files to an external PC (see Section 12.4.1: p.108). For example, LINE6.GPS may look like this: F1 $GPGGA,134218.00,4338.190204,N,07938.438411,W,2,05,2.
12-Survey & Map Mode 4) Noggin GPR data out port mode means that the GPR data stream will be output to the serial port of the DVL. This is for users who wish to read the GPR data into their own PC or other device. Contact Sensors & Software Inc. for more details if you want to use this option. Note that this option slows down data acquisition speeds. Baud Rate The baud rate is the speed that data is sent from the GPS receiver to the serial port of the DVL.
Noggin 12-Survey & Map Mode The End String option allows the user to fill in the 5 character GPS prefix. Use the Left and Right buttons to move left or right to different characters in the string. The currently selected character will have an “^” under it. To change the letter of the current character, use the Next button to change it to the next letter in the alphabet and the Previous button to change it to the previous letter in the alphabet.
12-Survey & Map Mode Noggin 12.4 Noggin File Management The File Management option is available by pressing 2 from the main Noggin menu. The File Management menu allows the user to delete data from the DVL and copy data from the internal compact flash drive to the removable compact flash drive. The Export options in this menu require the use of the optional PXFER cable and WinPXFER software so this menu is not required for users transferring Noggin data using the removable compact flash drive.
Noggin 12-Survey & Map Mode 12.4.2 Copying Noggin Data from the Internal Drive to the Removable Drive If data were collected to the internal drive of the DVL (Section 12.1.7: p.69), the data can be copied to the removable drive so the data transfer method described above can be used. To copy Noggin data from the internal drive to the removable drive, from the Noggin menu select 2 - File Management and then select 7 - Copy Internal to Removable. 12.4.
12-Survey & Map Mode Noggin 12.5 Noggin Utilities Pressing the number 4 on the main menu selects Utilities. This menu has utility programs to change the date and time on the DVL and also calibrate the odometer. 12.5.1 Time and Date The date and time are saved with the data files. The DVL date and time setting can be changed by moving to one or more of the appropriate fields and editing the current setting. The LEFT and RIGHT arrows are used to move between fields.
Noggin 12-Survey & Map Mode Odometer calibration values for the SmartHandle odometer should be around 1530. Odometer calibration values for the Vehicle odometer vary but may be around 50. 12.5.3 Upgrade Upgrade requires the use of the optional PXFER cable so this menu is not required for users who upgrade their DVL firmware using a removable compact flash drive. The menu allows the user to enter Upgrade mode to update the firmware on the DVL.
13-Troubleshooting Noggin 13 Troubleshooting Noggin Smart Systems are designed to minimize user problems; however, all electronic devices are subject to possible failure. The following are troubleshooting hints in the likelihood of occurrence if your Smart System fails to operate. 13.1 Power Supply The most common problem that can occur while trying to run a system is insufficient power. The battery may be dead or have a low voltage.
Noggin 13-Troubleshooting Make sure the cables are not damaged and that all cable connections are tightly secured. Use a slotted screwdriver to snug up the connections. Sometimes vibrations cause the cable connections to loosen just a bit and break contact and this can cause errors. Disconnecting cables and reconnecting them may provide a better contact and solve the problem. Turn the Digital Video Logger back on and try running the system again.
13-Troubleshooting Noggin If this error occurs, power the system down, power it up again and retry data acquisition. If the error persists, contact Sensors & Software Inc. (see Section 13.7: P.114). 13.6 Creating a Test Line for Data Quality One of the best ways of detecting problems with the GPR system is, shortly after receiving the system and getting comfortable with its operation, to collect a line of data at a convenient, easily accessible location.
Noggin 14-Care and Maintenance 14 Care and Maintenance 14.1 Battery Care Smart Systems use 12-volt sealed lead acid batteries. They are fused with a 10 Amp fuse to protect them from short circuit damage. The SmartCart battery unit uses contains a 9 Amp-hour battery. The battery unit should run the Cart Noggin for 4-5 hours before recharging is necessary. If long days of data surveying are typical, a second battery unit may be a useful item.
14-Care and Maintenance Noggin 2) When the system is not being used, make sure the connections are done up to prevent dust and moisture from collecting inside. If the connectors are exposed, cover them with some sort of dust cap. 3) Cables are designed to be as tough as practical. 4) Careless use of cables making them carry loads that they are not designed for can cause internal damage. 5) Connectors are weak points in any system.
Noggin 14-Care and Maintenance 14.5 Storage Cases Equipment that is transported and stored loosely is more susceptible to damage. All equipment should be stored in its shipping case or a storage box. Sensors & Software has shipping cases available as options for all Noggins and DVL’s. 14.6 Spare Parts For customers working in remote areas or if downtime in the field is unacceptable, consider buying our optional extended spares kit. This kit includes extra cables, batteries and chargers.

Noggin Appendix F - Using the PXFER Cable and WinPXFER Software Appendix F Using the PXFER Cable and WinPXFER Software F1 Transferring Data to a PC using the PXFER Cable There are two methods available to transfer data files from the DVL to a PC. The usual method is to save the data to the removable compact flash drive that is accessible using the door on the top of the DVL. After powering down the DVL, this drive can be removed and inserted into a card reader attached to a PC.
Appendix F - Using the PXFER Cable and WinPXFER Software Noggin F1.2 PXFER Cable Types There are two types of PXFER cable, Normal and Turbo. The Turbo PXFER cable can be identified by the pink band visible near the connector at either end. The Normal PXFER cable does not have this pink band. Figure F-2: Turbo PXFER cable. Figure F-3: Normal PXFER cable. Data transfer can only occur if the DVL is set to the correct type of cable (see F1.4: p.F-4).

It is vital that WinPXFER be configured properly for the type of PXFER cable (see F1.2: p.F-2). If the PXFER cable is a Normal cable, the Turbo option under Preferences should NOT be checked when attempting to transfer data.
Noggin Appendix F - Using the PXFER Cable and WinPXFER Software F1.6 Exporting Nogginplus Data Once the parallel XFER cable is connected (see above) and the WinPXFER software is installed and running, it is now possible to export data to the external computer. All the data in one or more Line or Grid Projects or the TAGGED.GPS file can be transferred to an external computer. From the main File Management menu, the user selects whether to export Line data, Grid data or the TAGGED.GPS file.
Noggin Appendix F - Using the PXFER Cable and WinPXFER Software F2 Transferring One or More Noggin PCX Files to an External PC using WinPXFER There are two ways of using the PXFER cable and the WinPXFER software to transfer Noggin data to an external computer. The first is to transfer one or more screens (or buffers) of data as a single PCX graphics file. This method is described in this section.

Noggin receiver (Rx) General term for electronics devices used to detect fields and translate signals into records or displays resolution The minimum separation of two objects before their individual responses merge into a single response signal amplitude A measure of the strength of the radio wave signal station interval Spatial distance between observation points along a survey traverse line or mesh points on a grid step size See station interval transmitter (Tx) General term used for electron
Noggin wavelet or EM pulse Impulsive GPR's emit an oscillatory electromagnetic pulse which is short in time and space and is often referred to as a wavelet. penetration depth The depth of a GPR wavelet can penetrate to before it is attenuated to an undetectable amplitude. air waves GPR systems can create and detect energy which travels through air above the ground. Undesired responses from above ground targets are often called 'air waves'.
