thank you very much Andreas for your mail. It helped me for the first
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
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
(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
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
fusion with TM picture and KVR-1000 (30 m and 3.09302918

Many Greetings

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