WorldComposer is a tool for extracting height map data and satellite images from the real world. It uses Bing Maps, just like the new Microsoft Flight Simulator 2020.
WorldComposer can create its own terrain, but the exported height maps (such as stamps) and satellite images can also be used for other terrain tools, such as TerrainComposer 2, Gaia, WorldMachine, MapMapic, WorldCreator, etc.
It is powerful and can create high-resolution AAA quality real world terrain with a few clicks.
