Hello, Andy from OSM’s Data Working Group here.
We’ve spotted what appears to be an organised mapping session for new mappers in Babahoyo in Equador. Problems there include new mappers being told to edit in exactly the same area, resulting in duplicate buildings a couple of minutes apart. Obviously this isn’t the new mappers’ fault - they literally only started editing yesterday. However, whoever is organising them probably could benefit from some advice. Does anyone have any idea who that might be?
So far, I’ve commented on a couple of the changesets, here and here.
