In doing this we always respect the work of local mappers, and follow community conventions. None of our edits are automated.

If there is anything we can do to be more open about our mapping projects I would be eager to discuss with you.<br clear="none"><br clear="none">Again, if you have specific concerns about edits any of our team members make in your local area, please! raise them in the changeset comments. It’s the single most effective way for us to learn how to to do better.
