[OSM-talk] lat=0 lon=0

[David Earl]

I notice from processing the planet file this week that there are over 
300 nodes (including two named ones - a waypoint and a village called 
Essai) and one zero length segment at lat=0,lon=0. This is, of course, 
in the middle of the ocean - I'm thinking something is creating these 
because of a bug.

I also see quite a lot of - several hundred - named ways with no 
segments. How is that these are being created? For example Croxford 
Gardens near Oxford is a valid way, but there are also four Croxford 
Gardens without any segments. They say created_by=JOSM, but the problem 
may have arisen later. They aren't new this week, its just I noticed them.

(Actually I'm puzzled how it is that if I locate the real Croxford 
Gardens and download the area(*) in JOSM, it brings in the four dead 
ones too, as I can't see how it is getting any bounding box information 
about those ways in order to determine that they are in that area. But 
it does)
