Is it better to have no information or some information that can potentially be slightly inaccurate?

Help and support

I am mapping this area in China: https://www.openstreetmap.org/#map=19/26.198018/119.540211 and currently it is blank. However the aerial imagery is not exactly clear and the buildings here are very dense so it sometimes can get very difficult to say if it is one building or two buildings. My question is: how would I map this area?

  1. Map the buildings that I can 100% tell are there. This ensures that what I map is accurate but it can give a false sense of “there’s not a lot of buildings here”
  2. Leave it blank.
  3. Map all the buildings and allow myself to take some leaps of faiths where maybe a few buildings would be incorrectly split or merged.

Hi SunnyMonster, welcome to the forum!

I would go for 3. Many places have been started in this way with poor arial imagery and building outlines just being estimated as good as possible. As soon as better imagery is available, yourself or other mappers can do refining work.

In my place there are many townships having been mapped in such way years ago. Whenever I come in touch with such an area, i do some refinement and step by step the map becomes more precise.

Have fun.
