Multiple 2D Map Views Multiple 2D Map Views 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. The map view manager maintains multiple 2D views of the data, which must be placed next to each other in the interface. They may contain different layers, and may be zoomed and panned independently, or linked in location and scale using the 2D Map View Manager settings.
For information about docking the 3D viewer, path profile or attribute editor, see Window Docking
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. Under the 'Add New Map View' section, add additional map views to split the 2D map view into multiple map views. New map views will be added relative to the highlighted map view or group.
Select the relative location from the 'Add New 2D Map View' drop down menu, and press the Add Map View... button to add a new 2D map view. The default position for the new map view will be to the right of the Main Map Window.
2D Map views can show different layers than the Primary Map View. They may also have the Map Layout layers (legend, scale bar, etc.) turned off independently. Highlight a view in the Main Map Window list and press the Select Layers... button to control the layers that display for that view.
Optionally set the views to have linked zoom and/ or center points using the check boxes.
Primary Map View
The Primary Map view is the dominant 2D view that is the one chosen for display controls like 2D/3D linking.
When a 2D map view is made the Primary Map View, the frame will indicate this with a shaded border. The map view manager will display 'PRIMARY MAP VIEW' after the map view name. In the below example the left map is the primary map:
Select Layers to Display in each View
Right click on a 2D map view and choose Select Layers to Display in View..., or highlight the layer and press the Select Layers... button at the bottom 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
Add Map View
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.
Link the Scale (Zoom) of All 2D Map Views
Check this option to link the scale of all 2D map views. When one map view is zoomed, the other map views will jump to the same scale.
If the maps begin at different scales when this option is enabled, the scales will sync when one of the maps is panned or zoomed.
Link the Center Points of All 2D Map Views
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.
Save/Restore Multi-View Layout to/from Workspace Files
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.
Additional Options
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.
The map view layout may also be saved in workspace file by checking this option. This is the default behavior.
This will save the map view layout to a Global Mapper view layout file (*.gm_views).
Select Layers to Display in View...
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.
