CGTalk - high-poly terrain

my current project is a pod-race through a desert-canyon type area. I used terragen as a foundation and created a flat, black and white image of the terrain. I also tried creating a mesh of this image (i exported to .lwo, converted to .obj, and imported into Maya). The imported terrain looked great, however the poly count was just too high. There were large, flat expanses with thousands of triangles... how can i remove the polys from the flat areas while keeping the detail in the rocky areas?

Can you cut out the flat areas and replace them with just one big plane and have the rocky areas siting ontop of that? Assuming your large expance is all on the same level of corse..

i gave that a try... but i guess there were simply too many polygons... i'm trying different methods for making this race course.

I've had this problem in the past and there are two ways to bypass it.... I cant give you exact parameters because i really cant imagine what it is like exactly that you are trying to do but there are two great tools for polygon reduction in maya.... Polygons/reduce options to make a uniform reduse of polygons for the object and, the best solution but needs a lot of parametrization is the Polygon/Cleanup option..... I hope i have been of some help.....
