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, ...
This structure was designed to enable composite line-polygon structures (e.g., the census block), address geocoding, and transport network analysis. It also had the benefit of increased storage efficiency and reduced error, because the shared border of each pair of adjacent polygons was only digitized once.
Geocoding is interpolating spatial locations (X,Y coordinates) from street addresses or any other spatially referenced data such as ZIP Codes, parcel lots and address locations. A reference theme is required to geocode individual addresses, such as a road centerline file with address ranges. The individual address locations have historically ...
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: Country code and subdivision code. Polygon ...
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]
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
Principles of geolocation using GPS. Geopositioning is the process of determining or estimating the geographic position of an object or a person. [1] Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum.
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".
