How about using the "SIFT" method to find GCPs and then run i.rectify to bring them together? Or, mosaik with SIFT, then georeferencing the resulting mosaik map to a modern orthophoto mosaik. Or, run each tile through i.ortho.rectify for a full approach. And then deal with the rail lines... Just an idea, Markus _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: http://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-user
