Geohash. The 6g cell and its sub-grid. Geohash is a public domain geocode system invented in 2008 by Gustavo Niemeyer [ 1] which encodes a geographic location into a short string of letters and digits. Similar ideas were introduced by G.M. Morton in 1966. [ 2] It is a hierarchical spatial data structure which subdivides space into buckets of ...
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, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. [ 1] Reverse geocoding, on the other hand, converts geographic coordinates to ...
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:
The W3C Geolocation API is an effort by the World Wide Web Consortium (W3C) to standardize an interface to retrieve the geographical location information for a client-side device. [3] It defines a set of objects, ECMAScript standard compliant, that executing in the client application give the client's device location through the consulting of ...

How to tag an article. For most geographically based articles lacking a coordinate, a { { coord missing }} tag was added to the article's source wikitext just below the External Links section. Replace it with { { coord |latitude|longitude|display=title}} suitably customized. Once the coordinate data is added, the article displays a mapping link ...
QGIS is a geographic information system (GIS) software that is free and open-source. [ 2] QGIS supports Windows, macOS, and Linux. [ 3] It supports viewing, editing, printing, and analysis of geospatial data in a range of data formats. QGIS was previously also known as Quantum GIS.
Geocoder. Geocoder (Ruby) is a geocoding library for Ruby. Geocoding helps to enhance webpages by presenting location relevant information to the user. When used with Rails, Geocoder adds geocoding functionality such as finding coordinates with street addresses or vice versa in addition to distance calculations for ActiveRecord objects. [1]
