Hallo,

thank you very much Andreas for your mail. It helped me for the first
step,
but there is the second: to get this dates together with other data.

I know, there is the modul r.proj.

I did the steps as they are described on the help manual. But after
minutes
of working the program creates an empty file.
Perhaps it has something to do with the Grid-Resolution: of the KVR-1000
satellite picture: 3.09302918. I set the Grid-Resolution af both
locations
(source location and the current location) on this Grid-Resolution.
I tested two variants with resolution value on r.proj:
3.09302918 and Default (calculated from the number of cols in input
map).
both with the same result: empty file.
Is there somebody with a good idea?

My aim is to make an image fusion. Is it at all possible to make an
image
fusion with TM picture and KVR-1000 (30 m and 3.09302918
Grid-Resolution)???

Many Greetings
Elke

P.S:
I worked with GRASS 5.0 Beta 3
The KVR-1000 pictue is a file with about 25 MB.
