The wiki says the OSM front end on openstreetmap.org is using GeoNames for the search. http://wiki.openstreetmap.org/wiki/Geonames Wondering because I might implement search functionality for a map myself, and because I'm curious.

How come GeoNames is used? Are there any benefits of doing this, instead of pulling the data from OSM? I mean locations and names are in the OSM dataset.

We use OpenStreetMap (Nominatim) and a range of other sources (if you enter a British postcode data from Free the Postcode are also returned). Geonames is used as well as Nominatim because:

  • it is open
  • created to be comprehensive, whereas OSM may depend on how well an area is mapped. 5 years ago when I joined OSM large areas of the UK, Spain etc didnt have place names let alone street names. Geonames did. So at least one could find an area for editing.
  • it's a useful supplement (particularly when OSM naming gets too detailed, try searching for the now non-existent administrative districts of Middlesex, Berkshire and Sussex on OSM - they dont appear from Nominatim because we have no objects tagged with these places
  • geonames may well be faster because of how it is run

So it's not either/or; Geonames is a supplementary, but useful, source for locations on OSM.

P.S. I suspect the wiki page is a 'living fossil'.
