Comment(by neteler): Replying to [comment:5 hamish]: > It seems to go beyond just EPSG codes, e.g. on the msys command line selecting the nad83 datum also returns no options, although etc/datumtransform.table indicates that 5 (+ the 1 default) should be available. > > {{{ > g.proj proj4='+proj=longlat +datum=nad83' datumtrans=-1 > g.proj proj4='+proj=longlat +datum=nzgd49' datumtrans=-1 > }}} > > both give no output. When adding "-d", it does give output: {{{ GRASS 6.4.3svn (nc_spm_08):~ > g.proj proj4='+proj=longlat +datum=nad83' datumtrans=-1 GRASS 6.4.3svn (nc_spm_08):~ > g.proj proj4='+proj=longlat +datum=nad83' datumtrans=-1 -d GRASS datum code: nad83 WKT Name: North_American_Datum_1983 Datum transformation parameters (PROJ.4 format): towgs84=0,0,0,0,0,0,0 GRASS 6.4.3svn (nc_spm_08):~ > g.proj proj4='+proj=longlat +datum=nad83' datumtrans=-1 GRASS 6.4.3svn (nc_spm_08):~ > g.proj proj4='+proj=longlat +datum=nad83' datumtrans=-1 -d GRASS datum code: nad83 WKT Name: North_American_Datum_1983 Datum transformation parameters (PROJ.4 format): towgs84=0,0,0,0,0,0,0 GRASS 6.4.3svn (nc_spm_08):~ > g.proj proj4='+proj=longlat +datum=nzgd49' datumtrans=-1 GRASS 6.4.3svn (nc_spm_08):~ > g.proj proj4='+proj=longlat +datum=nzgd49' datumtrans=-1 -d GRASS datum code: nzgd49 WKT Name: New_Zealand_Geodetic_Datum_1949 Datum transformation parameters (PROJ.4 format): towgs84=59.47,-5.04,187.44,0.47,-0.1,1.024,-4.5993 }}} No idea about datum "eur50", though. -- Ticket URL: <https://trac.osgeo.org/grass/ticket/1452#comment:26> GRASS GIS <http://grass.osgeo.org> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
