Subject:RE: map polygon data for popular us cities
View as plain text  
I remember a few years back I was doing some terrain modeling, and I think 
there was a repository of files on a US government web site. It's been so long 
that I don't remember what the file format was, but I was importing them into 
a 3D graphics program. There might be flattened versions.
