Overlay maps to georef?

tcatetcate Global Mapper UserPosts: 5
I have a series of maps that have unknown worldfiles and I'm going to have to manually georeference them. A few of the maps have identifiable points for georeffing but they are low resolution and will result in poor accuracy. However, if I could combine several maps in the left-hand georeffing pane, and make them semi-transparent, then I should have enough points to provide reasonable accuracy.

I'm using GM v6.08 and can't figure out how to have multiple layers in the left pane. Can it be done? Am I missing something simple?

    The left pane is only for the map you are currently rectifying, but if you could stitch your maps together into a single image prior to rectifying it then that would work.

    Let me know if I can be of further assistance.
