3.12.5 DEM Displays
The IDV supports elevation data from models, USGS DEM format and ESRI's ArcInfo ASCII grid format.
  1. If other displays and data are already loaded, select the Edit->Remove All Displays and Data menu item or the icon in the toolbar to clear them out.
  2. Load some DEM data.
  3. Create a display
  4. Where are we?
  5. Ok, so now we see that this DEM data set is to the west of Denver.
  6. Note that the DEM display is flat, it is just a plan view. Doesn't the IDV do 3D???
  7. Now, lets try to combine the Topographic map with the DEM data.
  8. Try changing the vertical scale to 5000-14000 feet (View->Viewpoint->Vertical Scale menu item).
  9. Lets just highlight the areas that are above 4000 meters.
