Creates a composite raster map layer by using known category values from one (or more) map layer(s) to fill in areas of "no data" in another map layer. http://grass.osgeo.org/grass64/manuals/r.patch.html another nice way, build a gdal virtual dataset (http://www.gdal.org/gdal_vrttut.html) with 2 or more DEMs outside of qgis/grass and r.external (Link GDAL supported raster file to a binary raster map layer: http://grass.osgeo.org/grass64/manuals/r.external.html) or r.in.gdal (Import GDAL supported raster file into a binary raster map layer: http://grass.osgeo.org/grass64/manuals/r.in.gdal.html) the virtual raster.
