First set the region to fit all maps, like suggested by Marcello.
Then, use r.patch to combine the maps.<br>

My problem begins, when I now try to add up all these single
maps into one larger map.<br>
I searched for a solution and tried several things, but
nothing worked.<br>
<br>
Any tipps or hinds?<br>

Hey,<br>
<br>
As always, there is probably a much more elegant solution to this
problem, but this should get you going for now:<br>
<br>
> g.region
rast=map1,map2
# just to make sure your region encompass everything<br>
> r.mapcalc
"bigmap=if(isnull(map1),99999,map1)+if(inull(map2),99999,map2)"
# replace nulls on the fly by a specific value that your data does
not contain<br>
> r.mapcalc
"bigmap=if(bigmap==99999,null(),bigmap)"
# put back the nulls<br>
<br>
Well, ugly like all my codes, but it works.<br>
<br>
Cheers,<br>
Marcello.<br>
