Quite a few sheets were done this way for Oxford. See

> I was lent 65 first-edition 1:500 OS maps of Ipswich dating back to

> The rules I have created says that all maps should be geo-coded, that
> the photos should be released CCBYSA and that the contributor agrees
> that the images can also be used to derive mapping for OSM (to cover

> The group is here:
> I have also just rectified one map using Warper. Four control points
> seemed to do the job very well.
> If anyone has any suggestions about adjusting the rules for the group
