Hello, I am working on a robotic simulator based on Blender.
I am using a small script [1] to generate terrain from aerial image and heightmap [2]. Those two images are quite big (9000x9000) with a 5cm per pixel resolution. My knowlwedge in modeling and mapping is quite limited, so I'm only using a grid and the "Displace" modifier, which limits me to a resolution of 50cm per pixel, and results in a model of 850K+ vertices and 1.7M+ tris [3].

I tried using the "Decimate" modifier, but it breaks the model (end up with a lot of holes in it). For info, my lab is using an eBee [4] for mapping.
