A geocode is a code that represents a geographic entity. 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 of the administrative boundaries of a country or a subdivision. The main examples are ISO codes: ISO 3166-1 alpha-2 code e.g. AF for Afghanistan or BR for Brazil, and its subdivision conventions, such as AF subdivision codes e.g. AF-GHO for Ghor province or BR subdivisio ...


Geocoding is the process of taking input text, such as an address or the name of a place, and returning a latitude/longitude location on the Earths surface for that place. Reverse geocoding, on the other hand, converts geographic coordinates to a description of a location, usually the name of a place or an addressable location. Geocoding relies on a computer representation of address points, the street / road network, together with postal and administrative boundaries. Geocode noun: is a code that represents a geographic entity location or object. Sometimes the term can be used in a broade ...

C-squares is a system of geocodes that provides a basis for simple spatial indexing of geographic features or data. It was devised by Tony Rees of CSIRO Marine and Atmospheric Research in 2001-2, and described in the literature in 2003. The notation system of c-squares incorporates a compact encoding of latitude and longitude coordinates into a machine- and human-readable c-squares code, which can then be used either for spatial search or display via a suitable mapping application. The c-squares codes also provide an application- and vendor-independent, interoperable notation system for an ...
