Steve Coast suggested changing the mission statement of OSM to be something like “The world’s best addressable map” I thought I'd separate out this into a new thread. As some backup, I attended my first SOTM-US in 2012 where Steve proposed we build an addressable map. A group of us from Seattle decided that we'd take that challenge and import addresses for Seattle. That import was completed.
Here are the address related comments: On Wed, Oct 22, 2014 at 4:37 AM, Martin Koppenhoefer <dieterdre...@gmail.com > wrote: > 2014-10-22 12:15 GMT+02:00 Steve Coast <st...@asklater.com>: > >> Together, we could do this in 6-12 months and finish addressing in 1-3 >> years.
