I have rendered a terrain based on RAW file which gives me the height information. Now I want to render a terrain based on a USGS Degital Elevation Model. I have a (.DEM)file of a perticular area (downloaded from net). The Advantage is that i ll get lat-long infos from DEMs, but i have no idea about (.DEM) file structure. Is there any parsing code available for DEM? Wait for any help.
With lot of thanks in advance.
