  2. Web Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Web_Mercator_projection

    The standard style for OpenStreetMap, like most Web maps, uses the Web Mercator projection. Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator [1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications. It rose to prominence when Google Maps adopted ...

    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. Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Mercator_projection

    The projection found on these maps, dating to 1511, was stated by John Snyder in 1987 to be the same projection as Mercator's. [6] However, given the geometry of a sundial, these maps may well have been based on the similar central cylindrical projection , a limiting case of the gnomonic projection , which is the basis for a sundial.

  5. Projected coordinate system - Wikipedia

    en.wikipedia.org/wiki/Projected_coordinate_system

    A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates (x, y) on a planar surface created by a particular map projection. [1]

  6. Universal Transverse Mercator coordinate system - Wikipedia

    en.wikipedia.org/wiki/Universal_Transverse...

    The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.

  7. World Geodetic System - Wikipedia

    en.wikipedia.org/wiki/World_Geodetic_System

    The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).

  8. Wikipedia:Obtaining geographic coordinates - Wikipedia

    en.wikipedia.org/wiki/Wikipedia:Obtaining...

    Google Maps tool – Coordinate converter: Online application to acquire coordinates for any place on Earth. Supports more than 3,000 coordinate systems and 400 datums worldwide. Place pushpins on the map and calculates automatically the coordinates in the selected coordinate system or datum.

  9. Geographic coordinate conversion - Wikipedia

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

    A coordinate system conversion is a conversion from one coordinate system to another, with both coordinate systems based on the same geodetic datum. Common conversion tasks include conversion between geodetic and earth-centered, earth-fixed ( ECEF ) coordinates and conversion from one type of map projection to another.
