I've found a pretty convenient tool for getting heightfield elevation maps



Now I just need to figure out a way to make the heightfield, the satellite
image, and the street map align and be scaled properly.

I also have "holes" in my heightfield when I try to texture it with an image
map.  They appear to be at places that are over a certain elevation.   Does that
ever happen?   CAN it ever happen?  I'd expect an image to be rgb in the range
of 0-1.
Is there a mechanism in POV-Ray to scale the rgb range of a heightfield image to
the proper range?
