I'm looking for the GIS data to create a topographic map of Bogota, Colombia; specifically, we want to get the elevation contour lines, and export that layer to CAD.
If anyone knows of any free places to find this data, we would love to hear it! I've been looking through some of the sources here http://freegisdata.rtwilson.com/ - but I'm not very familiar with that huge list. If anyone knows of a specific link in there that would be best to investigate, please let us know.
Thanks very much!
