Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1]
Geomessaging is a technology that allows a person or system to send a message based on any media to a device that enters or exits one or more regions. [1] Those regions can be created by using geofences, based on Latitude and Longitude, or adding beacons to the system associating those beacons with named locations.
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]
The 6g [1] cell and its sub-grid.. 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.
What3words (stylized as what3words) is a proprietary geocode system designed to identify any location on the surface of Earth with a resolution of about 3 metres (9.8 ft). It is owned by What3words Limited, based in London, England.
A 'geo' URI identifies a physical location in a two- or three-dimensional coordinate reference system in a compact, simple, human-readable, and protocol-independent way. [1] The current revision of the vCard specification [2] supports geo URIs in a vCard's "GEO" property, and the GeoSMS standard uses geo URIs for geotagging SMS messages.
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".
For example, for ISO, the country name “People's Republic of China” is a label. Geocodes are mainly used (in general as an atomic data type) for labelling, data integrity, geotagging and spatial indexing. In theoretical computer science a geocode system is a locality-preserving hashing function.
