I don't think so. It might be a matter of the Transformation type you 
have chosen.

[Qgis-user] Transform not solvable

2017-08-16 Thread Charles Barrows
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?
