Re: [OSM-talk-be] Mapbox, road completeness, CIA factbook

100% in Germany, The Netherlands, Luxembourg as well. Wonder why the
CIA thinks there are so many hidden roads in Belgium :-)
Or (more seriously) why the definition of road would be different for
Belgium compare to the other countries.

I cannot tell for Bolivia, but the Belgian roads are similar to other
Western European countries, so I would expect the CIA to use the same
definition there.

On the blog that was mentioned, you find a twitter address to contact
the Mapbox people. Maybe they can help ?

Yes, quite interested to hear more about this! 
Would be an excellent topic for a blogpost on openbelgium.be, or osm.be for 
that matter!

They analyse based on zoom level 12 tiles, a bigger margin of error for
smaller countries it says in the blogpost...

Maybe we can get the source of whatever mikel did and rerun in more detail
just for Belgium...

It might be the unpaved part, should be investigated further for other
countries.
