I am really struggling to rectify a map (05-05 SW) as it is so misaligned i can’t add many control points - i have 11 but one is in the ocean to see if it would help match the maps
I have been adding and deleting control points all day to try and get a erasable coverage but the map has been doing some peculiar warping.
It is mainly ocean so its hard to get a good spread and there are not many roads to match -
should i keep trying to find vaguely matched control points or is there some technique to overcome this problem
