- How to georeference a dxf? 5 answers
I've got some old maps in dxf format. QGIS imports them correctly but with a nonsense scale. It can export the data it gets to shp of course. Does anyone know how to rescale vector data so it can be related to other maps? It doesn't have to be done in QGIS as long as the method is open source and it works on a format QGIS can handle (SHP is best, of course).
Note that there seem to be two scales in SHP: the data I hand-imported using WKT shows the correct scale on the mouse, but the map scale indicated is nonsense, and print composer is affected the same way. I'd like to correct both types of problem.
