OfflineReverseGeocode

• An Offline Reverse Geocoding Java library
• Forked from https://github.com/AReallyGoodName/OfflineReverseGeocode
• This library provides offline reverse geocoding for GeoNames placenames and postal codes given a lat/lon. It uses k-d trees for extremely fast lookups.

Usage

Placenames Lookup

• First download a placenames file from http://download.geonames.org/export/dump/
• Allcountries.zip from that site is comprehensive however if you're on mobile try the cities1000.zip file. It's 1/80th of the size.
• Then simply
  ReverseGeoCode reverseGeoCode = new ReverseGeoCode(new FileInputStream("c:\\\\AU.txt"), true); System.out.println("Nearest to -23.456, 123.456 is " + reverseGeoCode.nearestPlace(-23.456, 123.456));

Postal Code lookup

• First download a postal code file from http://download.geonames.org/export/zip/
• Then simply
  ReversePostalCode reversePostalCode = new ReversePostalCode(new FileInputStream("c:\\\\AU.txt")); System.out.println("Nearest to -23.456, 123.456 is " + reversePostalCode.nearestPostalCode(-23.456, 123.456));
