[GRASS-user] correcting a series of images for wrong bounding box (extend)

[Tim Michelsen]

Hello,
I have trouble doing analysis on a couple of satellite images which have 
been recorded by the landsat sensor at different times in the past.

Some images have wrong or different bounding box coordinates and 
therefore do not overlay well on the others.

I tried already with the gdal-tools to warp the wrong image into the 
target extend, but they still ended up differently.
Now, I created a location in GRASS with the target extend and imported 
the wrong raster as well as the correct raster.
But when being overlayed, they are still shifted.

May someone please suggest me a solution?

The problem is that I cannot re-georeference the files because the 
current ground control points have disapeard or changed their location 
during times.

Thanks in advance for any hints and ideas.
Timmie
