Neither: just tag the areas that are used for residences as landuse=residential, and the area used for farming (mostly crops) as landuse=farmland. In OpenStreetMap we want to map what is actually there, not the zoning or legal landuse or property boundaries. This might change next year, just like an unmown meadow may change back into scrubland, and then eventually into woodland, or how a river will meander over time. Map what is there in reality right now, to your best ability. If people want to know the legal zoning or property boundaries there are plenty of data sources for that information, but OpenStreetMap is valueable because it provides local knowledge of what is really there. –Joseph Eisenberg On Tue, Jun 2, 2020 at 1:19 PM stevea <stevea...@softworkers.com> wrote: > Mateusz Konieczny <matkoni...@tutanota.com> wrote: > > I think that it is not a good assumption.
