[GRASS-user] Import a catalog of ascii *.arc files and merge to a raster

[Lars Forseth]

Hi!
In help for r.patch I found this:

MAPS=`g.mlist type=rast sep=, pat="map_*"`
g.region rast=$MAPS
r.patch in=$MAPS out=mosaic

That worked for me now.

I importet all files in the catalog by defining import source in the gui 
for r.in.gdal as directory; choosing the right directory; and it then 
imported all the files, giving them a "prefix" of x2; or some such.

I shall try Markus suggestions next!

regards; and thanks!
