[GRASS-dev] datums not recognized by g.proj?

[Michael Barton]

Markus,

It looks like some datums are not being recognized by g.proj. When this happens, datum transform information is not returned. Take a look at this.

wgs84 is recognized by g.proj

GRASS 7.0.svn (newLocation):~ > g.proj -d proj4='+proj=utm +datum=wgs84'
GRASS datum code: wgs84
WKT Name: WGS_1984
Datum transformation parameters (PROJ.4 format):
towgs84=0,0,0,0,0,0,0


but European Datum 1995 (eur50) is not recognized. This datum IS listed in ../etc/proj/datums.table

GRASS 7.0.svn (newLocation):~ > g.proj -d proj4='+proj=utm +datum=eur50'
WARNING: Datum <unknown> not recognised by GRASS and no parameters found
Datum name not present
Datum parameters not present

Unless I misunderstand something, this seems to be a serious bug because it affects location creation. I will file a bug report on this if you can verify.

Thanks
Michael
