[OSM-talk-be] Fwd: Administrative map of Belgium with mapping of the polygon to the municipality name or zip code?

[Alexander Mikhailian]

Sander,

I got the 14Mb of JSON data.

AFAIU, converting from OSM JSON to geojson should be rather easy
with something like osmtogeojson [1], and then, I'll be ready to
display it with D3.

Thanks a lot!
