The Add/Remove Map Views... command is found under the View menu, or on the Global Mapper Viewer toolbar. This tool enables dividing the main map view from a single 2D planar view, to multiple simultaneous views of the workspace data. Different map views may include multiple 2D or path profile displays, and a 3D viewer.
Once Add/Remove Map Views... is selected, the Map View Manager dialog will open.
Under the expandable Main Map Window section, the currently enabled Map Views are listed. The primary, 2D map view will always be listed as the 'PRIMARY MAP VIEW'. Under the 'Add New Map View' section, add additional map views to split the map view into 2 (or 3, 4, etc) map views. New map views will be added relative to the highlighted map view or group.
Select the map type for the new map view from the 'Add New Map View' drop down menu (2D, 3D or Path Profile), indicate the map position relative to the selected map view or window group from the next drop down menu. The default position for the new map view will be to the right of the Main Map Window.
If the map view is a 3D map type, then the new map view will also have the 3D View toolbar. The 2D and 3D map views may be linked using the 2D and 3D view linkage button .
Use the button in the 3D view toolbar to embed a 3D View window to a Map View, or to move an embedded Path Profile to a new floating window. Only one 3D map view/ window may be generated.
If the map view is a Path Profile type, use the Path Profile tool to draw the path profile, or generate a path profile from an existing line feature. By default the Path Profile tool will use this window to display the profile along the active path.
The Path Profile menu options visible in the floating window are available by right clicking on the embedded Path Profile map view.
To preserve a path profile and unlink it from the Path Profile tool, right-click on the Path Profile map view and deselect the option 'Use Profile View for Path Profile Tool' . This will preserve the current profile in the Map View, and open a new window when additional paths are drawn with the Path Profile Tool. There is no limit on the number of path profiles that may be generated.
Use the button in the Path Profile toolbar to embed a path profile window to a Map View, or to move an embedded Path Profile to a new floating window.
2D Map views can show different layers than the Primary Map View. They may also have the legend, scale bar, etc. turned on or off. These options are available by right-clicking the 2D map window in the Map View Manager (shown below). Any 2D map view can be made the Primary Map View.
When a 2D map view is made the Primary Map View, the frame will indicate this with a shaded border. In the below example the left map is the primary map:
The Primary Map view is the dominant 2D view that is the one chosen for things like 2D/3D linking.
To add a map view choose the type of view, and location. Then highlight the existing map view or group to base the positioning on, and click the Add Map View... button.
When this option is checked, and any 2D map view is moved (pan, zoom, etc.), all of the 2D map views will recenter on the center point of the active map view. This option does not affect zoom level, only map center.
This option is off by default. The setting will be stored in the workspace.
This will restore a saved view from a Global Mapper view layout file (*.gm_views). When a new view layout is loaded, any existing view layout is discarded and the new view layout from the file is applied.
To close a view, select the view from the Main Map Window (below) list in the Map View Manager and click 'Close Selected View...'.
This option will remove all views other than the Primary Map View.
This will save the map view layout to a Global Mapper view layout file (*.gm_views).
The map view layout may also be saved in workspace file by checking this option. This is the default behavior.
Select Layers to Display in View...
Right click on a 2D map view to control what layers display in the view. This option brings up the Select Layers dialog. This controls the Layers that display in the map view. The Overlay Control center is the master control for what layers are visible, but this option allows hiding layers within a given 2D map view. There is also an option to turn on or off the Map Layout Layers (Scale, Legend, etc.) set up in the Display Options Configuration
Zoom to Visible Layer Bounds
Select this option to zoom to the full extent of the layers enabled in the 2D map view.
Make Selected Primary View
Change the 2D Map view considered the Primary Map View. The Primary Map View is the 2D view linked to the Path Profile tool. It is also linked to the 3D view when the 2D and 3D view linkage button is selected.
