@Cebderby, no problems there, I initially aligned my imagery with a bunch of GPS traces I took and then compared to Cadastral parcel layer, which happened to fit properly anyway.

In any case, since not all of the local map features will have been created with the same alignment, I'm fitting/refining everything together at the same time.

Should look much neater after I'm done, and if need be, everything can be re-aligned mechanically after that point.
