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.
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
