Note that the very nice map you see in the screenshot above is not supplied with geontp since it is a commercial image (available from L3Harris) and cannot be freely distributed. Instead, I have included part of a free NASA image.
If you find a bug let me know.
Download geontp source code here. There are some instructions and setup hints in the README. You guessed it, no binaries.
