Reverse geocoding is the process of converting a location as described by geographic coordinates (latitude, longitude) to a human-readable address or place name.
In 2006, Reverse Geocoding and reverse APN lookup were introduced to geocoding platforms. This involved geocoding a numerical point location – with a longitude and latitude – to a textual, readable address.
In this case the latitude is 51.455558, and the longitude is -2.605047. The reverse is possible by entering the lat and long into the search bar, with a space between them.
In geodesy, conversion among different geographic coordinate systems is made necessary by the different geographic coordinate systems in use across the world and over time. Coordinate conversion is composed of a number of different types of conversion: format change of geographic coordinates, conversion of coordinate systems, or transformation to different geodetic datums. Geographic ...
The company has a website, apps for iOS and Android, and an API for bidirectional conversion between What3words addresses and latitude – longitude coordinates.
The forward projection transforms spherical coordinates into planar coordinates. The reverse projection transforms from the plane back onto the sphere. The formulae presume a spherical model and use these definitions: is the longitude of the location to project; is the latitude of the location to project; are the standard parallels (north and south of the equator) where the scale of the ...
The geographic [latitude/longitude] coordinate system is essential for referencing large areas of the Earth, but for small areas, it has serious drawbacks - it uses angular units (degrees, minutes and seconds), which are cumbersome when expressing distance or converting coordinate values between map scales, and the spacing of latitude and ...
EPSG:4326 - WGS 84 datum ensemble for 2D (latitude, longitude) coordinates with 2 meter accuracy, used by the Global Positioning System among others. EPSG:3857 - Web Mercator projection of WGS 84, used for display by many web-based mapping tools, including Google Maps and OpenStreetMap.
