What does latitude of origin mean?
Latitude of Origin—Defines the origin of the y-coordinates; this parameter may not be located at the center of the projection. In particular, Conic projections use this parameter to set the origin of the y-coordinates below the area of interest.
How does the Mercator projection work?
To keep longitude lines straight and maintain the 90° angle between the latitude and longitude lines, the Mercator projection uses varying distances between latitude lines away from the equator. As a result, the Earth’s poles and landmasses closest to them are distorted.
What kind of coordinate system is Web Mercator?
Web Mercator Coordinate System 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 was the latitude of the Mercator 1569 map?
Mercator 1569 world map ( Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendate Accommodata) showing latitudes 66°S to 80°N. The Mercator projection ( / mərˈkeɪtər /) is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569.
How does the Universal Transverse Mercator coordinate system work?
Universal Transverse Mercator coordinate system. The UTM system is not a single map projection. The system instead divides the Earth into sixty zones, each being a six-degree band of longitude, and uses a secant transverse Mercator projection in each zone.
When did Mercator projection begin to dominate maps?
Despite those position-finding limitations, the Mercator projection can be found in many world maps in the centuries following Mercator’s first publication. However, it did not begin to dominate world maps until the 19th century, when the problem of position determination had been largely solved.
