Description

Hello, for an archaeologyical project I'm rectifying aerial photographs with the georeferencer. But sometime I have the problem that I have not enough GCPs. So I need a tool to construct GPCs with intersection of straight lines (along dirtroads, streets, field edges aso.) in both views (GIS-map and georeferencer window).
I would be happy if you would take up this idea in your development of the georeferencer.

Best regards

you can compute intersection points with the proper tool in the "vector" menu and then use them as GPCs. Is enough?

Thank you for your fast answer,

but I think it will not help me. I need the intersection lines in both views to construct GCPs. In the georeferencer window and in the map window. There is a software, called Percor, that can this, but this is not a GIS and I can't use WMS maps aso.

This is a description of Percor: http://www.uni-koeln.de/~al001/percor_files/hs500.htm
