I have elevation rasters which loaded just fine in a GRASS session. They represent adjacent areas, so I want to meld them into one raster.
r.patch using the GRASS GUI, and it would only accept one input raster at a time in the
input files field. So I used the command line in a terminal window. The result was an error message saying that the rasters: cannot be found -- the directory does not exist.
r.patch, do the input files have to reside in the Location folder I'm using for the GRASS session? That doesn't seem right. GRASS had no problem finding the same files to simply load them into the map window.
I'm running GRASS on Ubuntu machines (11.10 Oneiric Ocelot). Thank you.
