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 ...
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).
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]
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 ...
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.
Geographic information science (GIScience, GISc) or geoinformation science is a scientific discipline at the crossroads of computational science, social science, and natural science that studies geographic information, including how it represents phenomena in the real world, how it represents the way humans understand the world, and how it can be captured, organized, and analyzed.
Computer cartography (also called digital cartography) is the art, science, and technology of making and using maps with a computer. [ 1 ] [ 2 ] [ 3 ] This technology represents a paradigm shift in how maps are produced, but is still fundamentally a subset of traditional cartography.
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]
