I want to calibrate a screen shot from google earth into Oziexplorer.
Unfortunatley there are not too many accurate points I can calibrate the image with. Maybe a few sandridges and merging dry creeks at best. Some of these are of questionable calibration worthiness.
In the help notes on polynomial calibration it says it can be used when the map projection is not known.
Can this work the other way in my favour, by "averaging" out the calibration points, even discounting to a certain extent calibration points of questionable accuracy?
