[GRASS-user] i.image.mosaic with ASTER GDEM

GRASS GRASS user

Hello,

i have 4x ASTER GDEM (geotiff) and want to put them together to extract
contours. I tryed it with i.image.mosaic but got the error-massage, that the
symbol "@" is not allowed in filenames. But my importet ASTER-Files are
automaticly set by grass to "ASTERXXX@aladaglar".

What I have to to, to put the ASTER GDEM together?

Thanks!
Martin

Please post the entire error message.

Alternatively, just try this:

g.region rast=ASTER1,ASTER2,ASTER3,ASTER4 -p
r.patch input=ASTER1,ASTER2,ASTER3,ASTER4 output=aster_mosaik
