Thanks SimonPoole, so I was thinking wrong about satellite imagery, but for now it is what it is.
I am going to walk to an open spot (inside or at the edge) of the village with a building I recognize on the satellite imagery and Gps mark that point in vespucci walk a few hundred meters to the next open spot and make a second mark, and maybe do 1 or 2 more in a line or square. Repeat it a couple of times to check gps variations. Now I can align the satellite imagery on those 2-4 marks and see what the result is compared to osm data. If it’s fairly oke (within 5 mtrs) I don’t move it, but I can add new buildings. This I repeat along the village, luckily the village is small. Sadly it isn’t allowed to use a drone inside the village for better contouring buildings, but this my first tryout.
