[GRASS5] Mosaicing adjacent raster maps

GRASS GRASS developer

Hi all,

Is there a way to join adjacent raster maps in one? More specifically, I have
a few adjacent DEMs each covering an area of a USGS 7.5" quadrangle. They fit
together with a small overlap of few rows and columns, so to be more exact, I
need to mosaic them.
Does anyone have any ideas how to go about it?

Thanks,

Aleksey

Thank you Moritz, this works. I must have overlooked this command
before...
