CDO can easily load the netcdf data and even remap it to other grids (although I am not sure how that works exactly); So maybe another way (if rotated pole is not possible with GRASS/gdal) I could try to transform using CDO and then import into a GRASS location....</p><p style="color:rgb(0,0,0)">/Johannes</p></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Oct 21, 2019 at 10:39 PM Markus Neteler <<a href="mailto:neteler@osgeo.org">neteler@osgeo.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi Johannes,<br>

AFAIK the data are in a rotated-pole coordinate system (<a href="https://is-enes-data.github.io/cordex_archive_specifications.pdf" rel="noreferrer" target="_blank">https://is-enes-data.github.io/cordex_archive_specifications.pdf</a>) which should be supported by GDAL (<a href="https://trac.osgeo.org/gdal/ticket/4285" rel="noreferrer" target="_blank">https://trac.osgeo.org/gdal/ticket/4285</a>) however I am unsure in which version of gdal (here I am using 2.2.2 (Ubuntu 16LTS, GRASS76)<br>

> I tried to use the location wizard to read the projection information from the netcdf file. However, here only a XY location (unprojected) is suggested. So how (and what) do I need to manually specify to define a Location that is able to correctly display CORDEX data? Any suggestions?<br>
<br>
Is there anywhere a file to play with?<br>
