I am mapping some rural areas. Basically there are 90% farmland, on some spots farm yards and even residential areas. I would no simply make the whole area farmland and put inside the farm yards and residential areas. Is this okay? Should I go even further and put natural wood on top of this landuse=farmland as they are quite small compared to the area of farmland? On which point should we start to make disjunctive landuses disjunct areas of landuse and when is it okay to nest them?
