<div>Markus,</div>
<div><br>
</div>
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.
<div><br>
</div>
<div>wgs84 is recognized by g.proj</div>
<div><br>
</div>
<div>
<div>GRASS 7.0.svn (newLocation):~ > g.proj -d proj4='+proj=utm +datum=wgs84'</div>
<div>GRASS datum code: wgs84</div>
<div>WKT Name: WGS_1984</div>
<div>Datum transformation parameters (PROJ.4 format):</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>towgs84=0,0,0,0,0,0,0</div>
<div><br>
</div>
<div><br>
</div>
<div>but European Datum 1995 (eur50) is not recognized. This datum IS listed in ../etc/proj/datums.table</div>
<div><br>
</div>
<div>GRASS 7.0.svn (newLocation):~ > g.proj -d proj4='+proj=utm +datum=eur50'</div>
<div>WARNING: Datum <unknown> not recognised by GRASS and no parameters found</div>
<div>Datum name not present</div>
<div>Datum parameters not present</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Thanks</div>
<div>Michael</div>
