Geohash is a public domain geocode system invented in 2008 by Gustavo Niemeyer which encodes a geographic location into a short string of letters and digits. Similar ideas were introduced by G.M. Morton in 1966. It is a hierarchical spatial data structure which subdivides space into buckets of grid shape, … See more The core part of the Geohash algorithm and the first initiative to similar solution was documented in a report of G.M. Morton in 1966, "A Computer Oriented Geodetic Data Base and a New Technique in File … See more A formal description for Computational and Mathematical views. Textual representation For exact latitude … See more An alternative to storing Geohashes as strings in a database are Locational codes, which are also called spatial keys and similar to QuadTiles. In some See more • List of geodesic-geocoding systems • Geohash-36 (is not a Geohash-variant) • Grid (spatial index) See more To obtain the Geohash, the user provides an address to be geocoded, or latitude and longitude coordinates, in a single input box (most commonly used formats for latitude and longitude pairs are accepted), and performs the request. Besides showing … See more Edge cases Geohashes can be used to find points in proximity to each other based on a common prefix. However, edge case locations close to each other but on opposite sides of the 180 degree meridian will result in … See more The Geohash algorithm was put in the public domain by its inventor in a public announcement on February 26, 2008. While comparable algorithms have been successfully patented and had copyright claimed upon, GeoHash is based on an entirely different … See more http://geohash.org/
