Hi there.
I understand there is a public domain terrain mesh with ca 30m resolution hosted on simviation.com. Also there is commercial meshes for various natural parks and the United States available.
There is a very impressive commercial textures package called "MegaScenery" that provides 5m satellite imagery for specific regions of the United States (currently L.A./San Diego and New York). As far as I understand this does not improve the terrain mesh resolution.
Is there a way to combine the high resolution meshes with the satellite textures? Has anyone ever done this? How would one set up or modify the directory structure to combine a mesh with a texture set from different vendors?
