[Bf-committers] Terrain modeling

I am working on a robotic simulator based on Blender.
I am using a small script  to generate terrain from aerial image
and heightmap .
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 .
My question is, is there a way to optimize the terrain using other
methods (bump mapping / shaders) ?
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  for mapping.
