I have several raster layers containing DEM data for an area of 1*1 degree each. I would like to “copy” those layers together having just one dem raster layer for the whole area. I started with r.mapcalculator using expressions like "max(A, … , F) " or A+…+F, but I always got an empy layer probably because the rasters dont overlap each other. Any idea how to do that? Shouldn’t be too difficult…

you can try r.patch input=mapA,mapB output=result
tip o' the day:
It's also useful to use g.region's multiple rast= capability to expand
the region to the extent of all maps automatically:
