[OSM-talk-be] more stats: data density in the Belgian regions

[joost schouppe]

Marc,

I was thinking about your "similar mappers" idea. of course, you can make
this very complicated (create a dataset of actions by users, then let loose
a similarity algorithm). However, it can also be very simple. For example,
using this [1] Overpass Turbo query, you can  get the usernames of all the
mappers who last touched a historic=monument thing. It wouldn't be very
hard to do this for a larger area and aggregate by user, so as to see who
thee bigger contributors are. It is a crude measure, but it's just to get a
list of people whose work you might want to check out, so I think it would
do.
You might want to download without the geometry and without first loading
in your browser when checking larger areas or wider queries.
