I had it all wrong. after ./overview.py 36 -117, I had to convert -flop -resize 300x300 -rotate -90 /tmp/overview.png /tmp/ovsmall.png to get it to match the tile between 36N, 117W and 37N, 116W, Mesquite Flat in Death Valley. and this was after adding in the missing bits by moving them into the "red" component. gives it a trippy look, and not all that useful, but it worked for the purpose: to determine the actual layout of the .hgt files. now I can move on to the next job, creating panorama views.
