Thanks fabianfred! So let me see if I understand this correctly: All I need to do to get it to load is change my map_h and map_t to grayscale instead of RGB?

I'll have to look and see what the problem is with the alignment. I did notice some SRTM data problems - little bumpy areas here and there - but it's possible I could have somehow screwed up my alignment when I cropped the images to get the 32x dimensions. I tried to crop each in exactly the same way, but maybe I didn't.

Yeah, map_F was just a place holder, to see if that was what was keeping it from loading.
