Hi, I have tried with GRASS 7.0.svn:

Is there a way to fix this? grass70 -c epsg:2972 ~/grassdata/test1 GRASS 7.0.0svn (test1):~ > g.proj -w PROJCS["UTM Zone 22, Northern Hemisphere", GEOGCS["grs80", DATUM["unknown", SPHEROID["Geodetic_Reference_System_1980",6378137,298.257222101], TOWGS84[2,2,-2,0,0,0,0]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433]], PROJECTION["Transverse_Mercator"], PARAMETER["latitude_of_origin",0], PARAMETER["central_meridian",-51], PARAMETER["scale_factor",0.9996], PARAMETER["false_easting",500000], PARAMETER["false_northing",0], UNIT["Meter",1]] --> DATUM["unknown", This happens when the datum is not understood by GRASS. One solution in the past for similar (not yet sure if it *is* similar) was to register the name, see: http://trac.osgeo.org/grass/browser/grass/branches/releasebranch_7_0/lib/proj/convert.c#L732 On the other hand, the spelling seems to be the same. No idea... Mhh, or are the CSV files included in lib/proj/ too old which we copied in the past from GDAL, then stopped due to PROJ4 issues (which are perhaps meanwhile solved)?
