Sure - also for us :) But it has been solved recently: r.external - Link GDAL supported raster file to a binary raster map layer. http://grass.osgeo.org/grass64/manuals/html64_user/r.external.html ... > I'd love to be able to be able to do the likes of > "r.shaded.relief input=mydem.tif output=myshade.tif" Yes, you can do that from 6.4.svn onwards: r.external [-r] in=/path/to/mydem.tif out=mydem g.region rast=mydem -p r.shaded.relief input=mydem shadedmap=myshade r.out.gdal myshade out=myshade.tif For r.out.gdal, check which format is appropriate to keep the color table if desired.
