  3. EPSG Geodetic Parameter Dataset - Wikipedia

    en.wikipedia.org/wiki/EPSG_Geodetic_Parameter...

    EPSG:4326 - WGS 84, latitude/longitude coordinate system based on the Earth's center of mass, used by the Global Positioning System among others. EPSG:3857 - Web Mercator projection used for display by many web-based mapping tools, including Google Maps and OpenStreetMap.

  4. GeoJSON - Wikipedia

    en.wikipedia.org/wiki/GeoJSON

    GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.

  5. Geohash - Wikipedia

    en.wikipedia.org/wiki/Geohash

    Since a geohash (in this implementation) is based on coordinates of longitude and latitude the distance between two geohashes reflects the distance in latitude/longitude coordinates between two points, which does not translate to actual distance, see Haversine formula. Example of non-linearity for latitude-longitude system:

  6. Open Location Code - Wikipedia

    en.wikipedia.org/wiki/Open_Location_Code

    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". Open Location Code is a way of encoding location into a form that is easier to use than showing coordinates in the usual form of latitude and longitude. Plus codes are ...

  7. Geographic coordinate conversion - Wikipedia

    en.wikipedia.org/wiki/Geographic_coordinate...

    Informally, specifying a geographic location usually means giving the location's latitude and longitude. The numerical values for latitude and longitude can occur in a number of different units or formats: [2] sexagesimal degree: degrees, minutes, and seconds : 40° 26′ 46″ N 79° 58′ 56″ W

  8. geo URI scheme - Wikipedia

    en.wikipedia.org/wiki/Geo_URI_scheme

    where the two numerical values represent latitude and longitude respectively, [1] and are separated by a comma. [1] They are coordinates of a horizontal grid (2D). If a third comma-separated value is present, it represents altitude; [1] so, coordinates of a 3D grid. Coordinates in the Southern and Western hemispheres as well as altitudes below ...

  9. Decimal degrees - Wikipedia

    en.wikipedia.org/wiki/Decimal_degrees

    Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree.DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices.
