Hi John,

Just to say that we've deployed an updated version - there's still a lot to
do, and some queries of course can get the overpass API to time out... but
e.g. here's a sample, looking at hashtag #crows2map (the mapathon
tomorrow), limited to Tanzania:


Scroll past the query boxes, to see the output.

Yes - I wished there was an URI like
http://tasks.hotosm.org/project/3296/bbox that gave you the bbox for the
task, and ideally ..../tiles as well.

That may not be needed, as you can just get the edits in that tile?

Each day scan all the uploads for unusual tags, discard those who weren't

Our tool does this, but you just have to enter the coordinates manually. I
think the tile may not be needed in the first instance, as it doesn't
really matter, as long as you can find the user? I would do the check per
project, and then message the user. Of course, if you want to give feedback
on the tile, then you need the tile.

If I understand you correctly, then we have this. Our tool outputs links to
OSM for each problematic object. (At the moment only to the OSM site, but
we'll amend this to load them in bulk into JOSM... when we have a moment -
it's easy to do).

At the moment, the list of tags that are deemed 'ok' is fixed, but it could
easily be changed.

I won't be there, but happy to participate remotely.
