GTK+ GRASS — Map Display
June 11th, 2009
No comments
The right pane of the GTK+ GRASS GUI displays several user controlled Map Layers. The map layers can be added or removed at any time. Each map layer has its own associated GRASS Region, and display list (previous post). To optimize drawing speed, the GTK+ GRASS GUI uses its own internal drawing routines for GRASS files and decorations. This may be changed with the new display used in GRASS7.
Display options include the usual interactive zoom window, zoom/out, and pan. The GRASS region can also be manually edited. The region can also be set to a raster or vector from the GRASS file selection view.
Display Toolbar
The map view can be maximized to fill the window, overriding the current GRASS region.
The position can be queried and captured, features can be measured, plus rasters and vectors can be queried from the display.
Display overlays (decorations) include:
- Raster colorbar.
- Vector legend.
- Scalebar.
- Grid.
- Geographic grid.
- Compass rose.
