I have a Georeferencer raster scan with 9 data points arranged in 3 rows of 3. I've checked the points out on the image for consistency of sequence, both x & y's, and they look good.
When I push the transform button I get the message "..:transform not solvable." I did make some mistakes while placing some of the data points, for which I deleted the bad ones and added new ones. Could the transform program be confused because the locations are now in a random order in the GCP table, or could it be something else? Charley
