[OSM-talk] Announcing Daylight Map Distribution

[Florimond Berthoux]

My proposal :

survey > aerial imagery.

So its the aerial imagery mapper who has to check that its aerial imageries
are more recent than the last changes made with survey sources.
That’s something I do often when I see weird differences.
(So we put the load on the big companies instead of the free local mappers
;)

Regards.
