Manuel answers a message I sent to him only. He includes all relevant parts of my message except the link to the arcgis result: https://sites.google.com/site/openfiles2/home/ilerfly125v2geoarcgis.7z?attredirects=0&d=1
Manuel, There is no wld file for the input layer The GCP table with errors can be seen here: https://sites.google.com/site/filestemp2/home/GCP.jpeg?attredirects=0&d=1 As I'm using gdallib1-1.8.0.2, could this be a gdal problem? Could anybody else using gdallib1-1.8 amd qgis1.7.3 verify (I provided all necessary material)? We have solved the practical issue for this particular image using another software, so we are not in a hurry. But I'm a bit surprised by the little attention that this problem is raising among developers. A correct georeferencing is a critical issue for a GIS. If this bug is confirmed, users should be warned.
