I have a simple desktop app with a map control. The map data that will be available to show will be either DTED files (Military Analyst's catalog / MADTEDLayer), or GeoTiffs (created by gdal). I want the user to be able to continuously see the elevation under the position of the mouse cursor. Is it possible to extract this information from the map layer somehow?
PS. I suppose that GeoTiffs have some kind of elevation data embedded since I opened them with GlobalMapper and saw height information under cursor.
