Maps Made Easy is now capable of accepting externally hosted DEM files (TIF or IMG) in various projections for processing into a Map Pilot compatible Custom Terrain Source. Map Pilot can also make use of these tiles as an elevation reference for Terrain Aware flight with a Custom Terrain Source. From this DEM Maps Made Easy also creates a set of depth tiles that are optimized for use in making volume measurements. Every time a job is run in Maps Made Easy a digital elevation model (DEM) is created. Map Pilot can use terrain model data that is created by processing imagery in Maps Made Easy.
