I am not worried too much about geometry offset, especially in rural areas where moving building to fix offset is usually not problematic. > Supplementary question, do you include or exclude conservatories, car ports > etc. from the main structure of the property? > It depends. I usually include them in case of armchair mapping of aerial images (unless there is a visible gap). In mapping during survey it depends whatever car port is part of a building structure or a separate structure standing next to house. > I guess at the back of my mind is what do people perceive as the purpose of > mapping (hope I have not opened a can of worms). > In my case I map what is useful for projects that I use/like or is very simple to map (=available as StreetComplete quest). So right now I map parking lanes for https://github.com/dabreegster/abstreet and in rural areas I tend to map hiking routes rather than buildings.
