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

[Marc Gemis]

An nice example is

http://overpass-turbo.eu/s/cMw

It seems that only 3 people has mapped power=minor_line in Belgium so
far (I didn't click on all results): Sanderd17, Mercator and escada
This is clearly not a popular feature

Another interesting one is barrier=fence. Again some clusters in certain areas.
