I'm trying to create a 3D model of California (which I'll manipulate in Blender) at a fairly low resolution — just enough for large features (like Mt. Tamalpais, Coronado, etc.) to be legible. Wherever I look, I find DEM's at much higher-resolution that would require a lot of stitching together and would likely tax my computer's capabilities. Any ideas? A bonus would be a DEM including Baja California too, but I realize most US sources won't have that data.

  • Sounds like getting the resolution I'm looking for (~100m) is known to be difficult: "The only problem with these data is when we need to make some analysis in a regional scale." carlosgrohmann.com/… – ed94133 Apr 5 '16 at 5:19

Trying Google reveals lots of free and open datasets out there. Here's one from NOAA at 1KM resolution. You can clip the global/continental dataset to your required area with any basic GIS software

  • Thanks, it's the number of datasets that makes this so hard. I hadn't seen that one, but looks like it's at the other extreme — this is too rough a rendering of the SF Bay Area: imgur.com/evwNZBT – ed94133 Mar 29 '16 at 23:15
