raster map I
have in a GRASS mapset in QGIS interface and it is not rendered, indeed
it is loaded but invisible. It seems QGIS recognizes the color palette
from GRASS and all but the raster map is not displayed (vector maps are
displayed correctly though). I tried with other raster maps from the
same mapset, changing color palette, but nothing happens either, map is
not displayed. I use QGIS 3.5 and
GRASS GIS 7.4 in a fedora 28 box.<br></div><div><br></div><div>Any ideas?</div><div><br></div><div>Thanks in advance,</div><div>Vero</div><div><br></div><div>ps: See a screenshot here: <a href="https://drive.google.com/open?id=1oGfVl-poy2tWL7Em6RwXu2TRkwAWMtW5" target="_blank">https://drive.google.com/open?id=1oGfVl-poy2tWL7Em6RwXu2TRkwAWMtW5</a> (otherwise my post does not go through)<br></div></div></div></div>
