Hi, So, the French people use data from their cadastre to build OSM. I have received from a notary an official map from the Belgian cadastre. Scan of a photocopy of a photocopy of... that's the technology. It is wrong. At first sight, there's an angle in one of the field sides that is straight on land and on a geometer's map. Further more, I tried every trapezoidal warp I could and I was unable to make a fit overlay to the PICC map (every time I adjusted one side, the other one went wrong). Anyone with a cadastre experience? Why don't they send people geodesic coordinates or a GPX trace of the fields? Cheers,
