Longitude

geoLucene is an extension of Lucene that allows to effectively index and search documents that contain locational information (longitude/latitude). It uses R-tree as a spacial index. See http://www.gossamer-threads.com/lists/lucene/java-dev/53378.

Written in Objective-C, the GeographicFormatter provides a Cocoa NSFormatter subclass for latitude and longitude output and input. There is also an IBPalette for integration with Interface Builder.

This library is a basic implementation from the GeoHash algorithm written in the java can be used to generate from the latitude and longitude a geohash code and reverse. For more information go to (http://en.wikipedia.org/wiki/Geohash)
