From time to time I mess around with this little side project. It's a mashup of #python #panda3d #jsbsim #srtm terrain and online map tiles forming a simplistic flight simulator. I have been looking into #GeoDeep which can find trees and other objects in the imagery as an idea for populating the world with realistically placed objects.
