Planetary mapping

GIS Support

• GRASS lat/lon regions may be used as 0-360 longitude, not just 180 east+west.

• You can set and add custom ellipsoids, see the g.setproj module. Custom ellipsoids have to be added by hand, but the config tables for that are plain self-documenting text files, so reasonably easy to edit. We would of course be happy to include standard planetary ellipsoids along with future versions GRASS, as they become available.
