[postgis-users] Address for a given lat/Lon

[suraj birla]

Hi ,
I've a requirement to get the address ( country, state/provinces, postal
code) for a given lat/lon. I need to this for 100 million+ records.

I'm planning to do this in 3 phases
First find the country using world polygon
Second find the state/provinces for the identified country
Postal code ???

Question.
1.Whether my approach is correct?
2. Where can I find the polygon for the world map by country.
3. How I can find postal code ?

Thanks
Suraj
