Anybody know a good way to do offline reverse geocoding? -

-

i need offline reverse geocoding, meant run cron-jobs. reverse coder should give city, state millions of 'records'.

what services exist ( paid or free ) can 'it'?

i've looked @ http://www.geonames.org/, that's not need.

get table coordinates of cities (and state city in). coordinate, pick closest city. efficient use, encode table r-tree.

for links on r-tree etc, see reverse geocoding without web access

get cities table geonames, see given lat/long coordinates, how can find out city/country?
