South America DEM

[tippkid]

Hello,

I am in need of a DEM for all of South America (free). I have tried googling this, but with no luck. The DEM does not need to be high resolution. 1km would do. Any web sites out there that I can download free DEMs?

Thanks.

Try searching for SRTM. The basic data is free but finding a usable DEM for the particular area you want without any holes or errors can sometimes be a pain.

It's not DEMs, but http://www.naturalearthdata.com/ has nice information. http://www.ngdc.noaa.gov/mgg/global/global.html is a good source for DEMs. http://www.ngdc.noaa.gov/mgg/topo/gltiles.html also works well.

Thanks everyone for the help! I actually found a decent DEM from WORLDCLIM.

Here is a GREAT tut on working with DEMs hosted right here!

It even shows you how to get the info you want out of the whole thing. Meaning the location that you want. Well worth the read
