GIS Support

  • GRASS lat/lon regions may be used as 0-360 longitude, not just 180 east+west.
  • In GRASS 6 you can set and add custom ellipsoids, see the g.setproj module. Permanently adding custom ellipsoids can be done by hand, the config tables for that are plain self-documenting text files, so reasonably easy to edit. An ellipse table with planetary spheroids (to put as $GISBASE/etc/*.table files) is available here.
  • GRASS 7 now includes the planetary ellipsoid tables and support is present in the wxGUI location wizard.

Open Issues

  • r.out.gdal exports 'unknown' ellipsoids / datums, and also the reference meridian is named 'Greenwich'

Example of the use of GRASS GIS in Planetary Research

GRASS ps.map output as published in an article in the journal Science.
