How to create a terrain using GIS terrain data

Maybe, you can direct me where I can find some documents / answers to achieve my goal, or just please give me your answer directly here.
My aim is to visualize a real-world street using its relevant GIS terrain data(DEM - ascii based e.g. longitude, algitude, height), and 3D models of houses which I did in Maya. My current understanding is the DEM data should be converted to a heightmap first ( which is a grayscale png file, for example). How should I start to write my code to create the terrain using that heightmap? Any example code avaialble?
Appreciate your help in advance!

Thanks. However, what I want to do is to create the terrain based on a height map automatically using the SDK code, instead of manually using the Wolrd Editor.

Your best bet may be to write a converter that creates .ter files. You should look at the "terrain/terData.cc" to see how the file format works.

search for GIS/DEM.

I belieive there is a well put-together post or resource on this somewhere.search for GIS/DEM.
