  2. Geohash - Wikipedia

    en.wikipedia.org/wiki/Geohash

    Geohash is a public domain geocode system invented in 2008 by Gustavo Niemeyer [2] which encodes a geographic location into a short string of letters and digits. Similar ideas were introduced by G.M. Morton in 1966. [ 3 ]

  3. Geocode - Wikipedia

    en.wikipedia.org/wiki/Geocode

    Geocode cells of Geohash, with 8 (blue) and 9 (yellow) digits, a typical hierarchical grid, comparing with latitude-longitude (12 or more digits). A museum is a typical location to be pointed by a geocode, its gate need ~20 meters of precision.

  4. Geohash-36 - Wikipedia

    en.wikipedia.org/wiki/Geohash-36

    The Geohash-36 geocode is an open-source compression algorithm for world coordinate data. It was developed as a variation of the OpenPostcode format developed as a candidate geolocation postcode for the Republic of Ireland. [1]

    en.wikipedia.org/wiki/Address_geocoding

    Geocode (verb): [2] provide geographical coordinates corresponding to (a location). Geocode (noun): is a code that represents a geographic entity (location or object). In general is a human-readable and short identifier; like a nominal-geocode as ISO 3166-1 alpha-2, or a grid-geocode, as Geohash geocode.

  7. Open Location Code - Wikipedia

    en.wikipedia.org/wiki/Open_Location_Code

    The Open Location Code (OLC) is a geocode based on a system of regular grids for identifying an area anywhere on the Earth. [1] It was developed at Google's Zürich engineering office, [2] and released late October 2014. [3] Location codes created by the OLC system are referred to as "plus codes".

  8. Discrete global grid - Wikipedia

    en.wikipedia.org/wiki/Discrete_global_grid

    Geohash: 2008 – CC0: original: Is like a bit-interlaced latLong, and the result is represented with base32. Geohash-36: 2011 – CC0: original: Despite the similar name, does not use the same algorithm as Geohash. Uses a 6 by 6 grid and associates a letter to each cell. What3words: 2013 patented original (English)

  9. Geotagging - Wikipedia

    en.wikipedia.org/wiki/Geotagging

    The related term geocoding refers to the process of taking non-coordinate-based geographical identifiers, such as a street address, and finding associated geographic coordinates (or vice versa for reverse geocoding). Such techniques can be used together with geotagging to provide alternative search techniques. [citation needed]
