Default Re: Dem/Topography question

Dave,
I get elevation data from this site: http://data.geocomm.com/catalog/US/6.../group4-3.html

You can download the data for free using the green download arrows.

There's a free program called sdts2dem.exe. Use that to create the DEM file. (just copy sdts2dem.exe into the folder with the elevation files and run it)

I then use polytrans (not free) to import the DEM data, export to a 3ds, and import into max.

I think you can also import the DEM data directly to max, but it is a super heavy mesh. Polytrans does a much better job of interpolating the data into a usable mesh.

If anyone has a better/faster method than that I'd also like to know about it
Hope that helps,
