I'm trying to open a scan of a map as a *.tif and register it. However, Georeg balks and gives an 'invalid registration' error. How can the registration be invalid? There _is_ no registration! What is most perplexing is that I've performed this little procedure several times before. By contrast, Worldreg opens the image, though with no projection of course. Looking for your suggested solutions.
