A Mercator map can therefore never fully show the polar areas (but see Uses below for applications of the oblique and transverse Mercator projections). The Mercator projection is often compared to and confused with the central cylindrical projection , which is the result of projecting points from the sphere onto a tangent cylinder along ...
A transverse Mercator projection. The transverse Mercator map projection (TM, TMP) is an adaptation of the standard Mercator projection.The transverse version is widely used in national and international mapping systems around the world, including the Universal Transverse Mercator.
A Cornucopia of Map Projections, a visualization of distortion on a vast array of map projections in a single image. G.Projector, free software can render many projections (NASA GISS). Color images of map projections and distortion (Mapthematics.com). Geometric aspects of mapping: map projection (KartoWeb.itc.nl).
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.
With no distortion along the central meridian and the equator, distances along those lines are correct, as are the angles of intersection of other lines with those two lines. Distortion is lowest throughout the region of the map close to those lines. A sinusoidal projection shows relative sizes accurately, but distorts shapes and directions.
The straight-line distance between the central point on the map to any other point is the same as the straight-line 3D distance through the globe between the two points. c. 150 BC: Stereographic: Azimuthal Conformal Hipparchos* Map is infinite in extent with outer hemisphere inflating severely, so it is often used as two hemispheres.
Chances are high that one of the first things that comes to mind is not Earth itself, but a map of it. One map in particular: Credit: Getty Images. Known as the Mercator projection, after the cartographer Gerardus Mercator, who first conceived of it in 1569, it’s ubiquitous in classrooms around the world. The map demands authority.
The Behrmann projection with Tissot's indicatrices The Mercator projection with Tissot's indicatrices. In cartography, a Tissot's indicatrix (Tissot indicatrix, Tissot's ellipse, Tissot ellipse, ellipse of distortion) (plural: "Tissot's indicatrices") is a mathematical contrivance presented by French mathematician Nicolas Auguste Tissot in 1859 and 1871 in order to characterize local ...
