An example of a relative geocode is "Across the street from the Empire State Building." The location being sought cannot be determined without identifying the Empire State Building. Geocoding platforms often do not support such relative locations, but advances are being made in this direction. Absolute input data
A geocode fragment (associated to a subdivision name) can be an abbreviation, numeric or alphanumeric code. A popular example is the ISO 3166-2 geocode system, representing country names and the names of respective administrative subdivisions separated by hyphen.
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.
In theory, every part of a picture can be tied to a geographic location, but in the most typical application, only the position of the photographer is associated with the entire digital image. This has implications for search and retrieval. For example, photos of a mountain summit can be taken from different positions miles apart.
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 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".
Geohash is a public domain geocode system invented in 2008 by Gustavo Niemeyer [2] ... For example, the coordinate pair 57.64911,10.40744 ...
The World Geographic Reference System (GEOREF) is a geocode, a grid-based method of specifying locations on the surface of the Earth.GEOREF is essentially based on the geographic system of latitude and longitude, but using a simpler and more flexible notation.
