Hi, Not sure if this or its been superseded, you might want to take a look at OSGTDS. http://andesengineering.com/Projects/TDS/
This is for deforming terrain for the placement of objects. I have never used it, but it might be worth a shot?

Hi, I managed to load some 200000 buildings from a freely available GIS database from the city of Winston-Salem and I render them with OSG. Buildings floating in space look kind of funny though and I need a ground, a horizon and some sky. I do not want to use a flat ground geometry or sky dome - that's too old-fashioned. I was thinking to use a screen aligned quad (coordinates forced to screen dimensions in a vertex shader) and a pixel shader to set ground and sky zbuffer values and to render the ground and sky color. The ground zbuffer values for sure depend on the camera height over ground. And how the horizon is oriented would depend on the camera orientation (view matrix) Unfortunately having little prior experience with GLSL, I think I might need some input from the community how to pull this off.
