So I show the OSM website to someone at work today, and their first response is "my street isn't on the map"
This is weird - the person lives in Bedford which is within range of at least 2 OSM mappers. So what went wrong?
Well it turns out that they live in an estate that was still a muddy construction site just 2 years ago when the area was last surveyed. Since then it's become a housing estate with loads of dodgy modern houses in various stages of construction.
So I went to visit and made a map of the area. But watch out -- something which is a cornfield one day may be someone's house the next day, and if you only visit the place once you might miss it...
(use osmarender layer to see latest maps, while mapnik is still showing old maps)
