Another option would be to gdal_translate to a .vrt by using
-a_srs srs_def EPSG:31466
-a_nodata value # in case you happen to know
-a_ullr ulx uly lrx lry # coordinates at pixel edges, not their centre
points
Think about the .vrt as being the big brother of a world file. You
might want to spend some time reading the documentation at [1], [2]
and [3].

but when i now try to translate by
C:\Program Files (x86)\FWTools2.4.7>gdalwarp -s_srs EPSG:31466 -t_srs
EPSG:25832 "D:\City\raster\gas\500\g8746-1_cit.tif"
"D:\City\raster\gas\500\g8746-1_cit_epsg_utm.tif"
i get following message:
Copying color table from D:\City\raster\gas\500\g8746-1_cit.tif to new
file.
Creating output file that is 0P x 0L.
ERROR 1: Attempt to create 0x0 dataset is illegal,sizes must be larger
than zero
.
did anyone / you have a idea how to translate successfully?
alternative to edit the coordinates manuell in the tif-file?
it is very important for me.
