When georeferencing a map image I get an error “Unable to create geo data file”?
A. The information calculated when you georeference a map image is saved to a small text file with the same name as the map image but with a .wld file extension. In order for Spitfire to find this geo data when the map image file is later opened it must reside in the same folder. Ensure that your disk is not full and that the media is writeable. If for example you are trying to georeference an image that is on a CD-ROM, copy it to your hard disk first.
