Geocoding relies on a computer representation of address points, the street / road network, together with postal and administrative boundaries. Geocode (verb): [2] provide geographical coordinates corresponding to (a location). Geocode (noun): is a code that represents a geographic entity (location or object).
Open Location Code. The Open Location Code ( OLC) is a geocode based in 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 ".
Geocode. A geocode is a code that represents a geographic entity ( location or object ). It is a unique identifier of the entity, to distinguish it from others in a finite set of geographic entities. In general the geocode is a human-readable and short identifier. Typical geocodes and entities represented by it:
Natural Area Code. The Natural Area Code, or Universal Address, is a proprietary [ 1] geocode system for identifying an area anywhere on the Earth, or a volume of space anywhere around the Earth. The use of thirty alphanumeric characters instead of only ten digits makes a NAC shorter than its numerical latitude / longitude equivalent.
Reverse geocoding is the process of converting a location as described by geographic coordinates (latitude, longitude) to a human-readable address or place name. It is the opposite of forward geocoding (often referred to as address geocoding or simply "geocoding"), hence the term reverse. Reverse geocoding permits the identification of nearby ...
Geotagging. Geotagging, or GeoTagging, is the process of adding geographical identification metadata to various media such as a geotagged photograph or video, websites, SMS messages, QR Codes or RSS feeds and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though they can also include altitude ...
A geographic information system ( GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. [ 1][ 2] Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. [ 1] In a broader sense, one may consider such a ...
what3words .com. 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. The system encodes geographic coordinates into three permanently fixed dictionary words.
