I am using ArcGIS 10.3. A collegue in Asia georefferenced a .tif image for me using the ArcGIS georeferencing tool. He uses the same version of ArcGIS. Before rectifying he saved the link table. He send both, the link table and the georefferenced image. Trying to adjust some of the georeferencing, I opened the original image and imported the link table. After having imported the link table, the source points are about 2 km west and 2 km north of what they should be. I cannot figure out, why. My collegue and me both use the same coordinate system (WKID 32642, WGS_1984_UTM_zone42M). Does anybody know what could be the problem?

Thanks,

Georg

Do you have any idea where these come from? Why would the georeferencing tool record image coordinates?

From-To points.... ie.  this image position is this real world  coordinate (row/column to real world)


... sort of retired...
