hi, thanks for your comment. Does this hold true even if no eveidence exists anymore that there was ever a building there? Quite a while ago I talked to the local landuse agency in Neustrelitz about these old farming buildings that were already quite rotten at the time. They told me they were going to "rebuild" the area and integrate it into the nature conservation area. I was there at the time of the note and was surprised that really, if you did not know there was ever a homestead you could not have guessed. So I assume it may be closer to truth to delete any existing building polygons at this site? Sorry for the long text :)
