Simple mistake, but amazingly deceptive results.
The image_map was never rotated x*90, and I think it was just shifted so that it
didn't extend up that far.   :|

I'm not using Sketchup, I'm just using the web-based Height Mapping tool to get
the grayscale map.   Then Google Maps to get the satellite and street maps.

Still having a bit of a struggle getting the overlay textures aligned to the
topolgy, but perhaps some more searching and experimenting will give me good
results that are easily reproduced with other locations.

Posting progress over on pbi
