[Maps-l] Nominatim

Hi everyone,

As you might know I uploaded 250.000 images from 
http://www.geograph.org.uk/ to Wikimedia Commons. Of course these images 
need to be categorized. For this I use reverse geocoding : I know 
coordinates of the location, I just need to know the name of the location.
I used http://ws.geonames.org/extendedFindNearby for this (worked at 
that time, seems to be down at the moment). Results seem to be pretty 
good, but some more accurate results would be nice.

Someone had already pointed out to me that I could use the reverse 
geocoding feature of Nominatim 
(http://wiki.openstreetmap.org/wiki/Nominatim) to categorize images at 
Commons. I just implemented it and this tool seems to catch a lot of 
images in the overcrowded categories. Would it be possible to set up a 
local copy of this tool at the OSM toolserver?

Maarten
