28 Tutorial 2: Working with Data
Oasis montaj Maps
In Oasis montaj, a Map is more than a printed sheet of information. Maps are special
items that serve a number of purposes in the system. The map window provides the basic
mechanism for creating maps, displaying images, and linking to other maps and data. To
work effectively with maps, you need to be familiar with the purposes of maps in the
system as well as the role of Views and Groups.
Maps use Views to organize and display information. A View divides the information on a
map into a Base view, (e.g. map surrounds, north arrows, and scale bars) which uses paper
coordinates, and a Data view, (e.g. map coordinates, contours, and grids) which uses
ground coordinates.
Maps use Groups to determine the order in which objects are displayed (rendered) on a
map. Groups are layered on top of each other in a specific order determined by the Map
View/Group Manager Tool.
Displaying a Map
1. On the Map menu, click Open map. The Open Map dialog box is displayed.
2. Select the map file (Oasismontaj.map) and click [Open]. The map is opened in
your project.
Adding Map Comments
1. On the Map menu, click Map comments.
2. The Default Text Editor (i.e. notepad) is displayed.
Note: If you have not specified your Default Text Editor, the Select a default text
editor dialog is displayed. Using the [Browse] button, locate a text editor on
your computer (notepad is recommended), and then click [OK].
3. Type your comments in the window, then save the file and exit the text editor.
The comments are saved in the map file (*.map file).
Using the Map View/Group Manager Tool
You can use the Map View/Group Manager tool ( ) to display and edit the Views and
Groups in a map. This tool consists of a ‘tree’ structure that contains two main branches
representing the Base view and the Data view. Under each view, a number of groups are
listed according to their layer on the map
Each group in a view shows an icon beside its name that identifies the group as either a
map vector object ( ) or an aggregate ( ). Views can either be normal 2D views ( ) or
3D views (
). The check boxes in the tree controls and indicates visibility of an item.
To select single items in the tree click on the item desired. Multiple selections of groups
within a view can be achieved by holding the <Ctrl> key and clicking on the desired
items. Changing the selection during group editing will end group editing without
cancelling any current changes.
