It would be a good feature to give us the option to align a past map to a new one. If we had a button to click to pick a map to align to it would let us take an older map that may not have used GCP’s with one that has. Just like the feature alignment processing currently has. The problem would be if there weren’t enough features so I am not sure how that would work. If it doesn’t work out we can probably re-reference maps in QGIS and import them back in right? @Andrew_Fraser @Jamespipe Thanks!
