What is the current Web Mercator projection code?

Web Mercator is a slight variant of the Mercator projection, one used primarily in Web-based mapping programs. It uses the same formulas as the standard Mercator as used for small-scale maps.

Is WGS84 a Web Mercator?

The Web Mercator coordinate system is also known as Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator, and Pseudo-Mercator. It is the de facto standard for web maps and online services.

What projection is Web Mercator?

The Web Mercator / Pseudo Mercator projection is a cylindrical map projection. This is a variant of the regular Mercator projection, except that the computation is done on a sphere, using the semi-major axis of the ellipsoid.

Is WGS 1984 Web Mercator auxiliary sphere?

WGS 1984 Web Mercator and WGS 1984 Web Mercator (Auxiliary Sphere) use a conformal projection that preserves direction and the shape of data but distorts distance and area. Published in 1569 by Gerardus Mercator, the Mercator projection was created for use in navigation.

What projection is EPSG 3857?

Spherical Mercator projection coordinate

EPSG:3857 is a Spherical Mercator projection coordinate system popularized by web services such as Google and later OpenStreetMap.

Is WGS84 the same as UTM?

The difference is that WGS 84 is a geographic coordinate system, and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees).
 

Is UTM a Mercator?

UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width.

What projection is WGS84?

For example, the “WGS84 projection” is a geographic one. A UTM projection is a projected one. Either of these will use only one datum. However, the data on the map could have come from multiple sources, all with unique projections and therefore datums.
 

What is WGS84 pseudo Mercator?

Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator 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 it in 2005.

What replaced the Mercator projection?

What format is WGS84?

WGS 84 BASICS



The WGS 84 Coordinate System is a Conventional Terrestrial Reference System (CTRS). It has a right-handed, Earth-fixed orthogonal coordinate format. The system origin also serves as the geometric center of the WGS 84 ellipsoid, and the Z-axis serves as the rotational axis of this ellipsoid of revolution.
 

What is WGS84 based on?

The World Geodetic System 1984 (WGS84) is the reference frame used by the Global Positioning System (GPS) and developed by the USA Department of Defense (DoD). It is now maintained by the U.S. National Geospatial Intelligence Agency (NGA). WGS84 has been revised six times since its original realisation in 1987.
