[OSM-talk-be] What could you map ? / Wat kan je mappen ?

[Jo]

At best, it's another data source to be combined with survey, aerial
photography, Mapillary. But it will be better if it doesn't frustrate the
user for having bugs in it. Gerard expressed in interest in addresses and
thus I thought he might be interested to know that new data source will
become available soon(ish). Faster if more of us can pitch in with the
testing.

Cheers,

Jo
