The convergence angle (CA) is the actual angle on a chart formed by the intersection of the Greenwich meridian and another meridian; the pole serves as the vertex of the angle. CAs, like longitudes, are measured east and west from the Greenwich meridian. Many major online street mapping services (Bing Maps, Google Maps, MapQuest, OpenStreetMap, Yahoo!Maps, and others) use a variant of the Mercator projection for their map images called Web Mercator or Google Web Mercator. Despite its obvious scale variation at small scales, the projection is well-suited as an interactive world map that can be zoomed seamlessly to large-scale (local) maps Define Mercator chart. Mercator chart synonyms, Mercator chart pronunciation, Mercator chart translation, English dictionary definition of Mercator chart. Mercator projection n.

On a mercator projection chart, lines of latitude are parallel as are lines of longitude. On gnomonic projection charts, meridians converge and lines of latitude are  On a Mercator chart meridians are parallel lines of longitude even at the poles, where meridians actually converge. This distortion at high latitudes is a  Gerhardus Mercator facts: The Flemish cartographer Gerhardus Mercator for his great world map, or chart, using the projection that has acquired his name. It also signaled the late Renaissance convergence of academic cartography with   29 Jun 2018 Longitude, right, has meridians that converge at the poles and are And like other map/chart projections, Mercator charts do involve distortion.

The position of magnetic north is governed by natural forces, but grid north is entirely artificial. In Cartesian coordinate systems, whether known as State Plane, Universal Transverse Mercator, a local assumed system or any other, the direction to north is established by choosing one meridian of longitude. The meridian that is chosen is usually in the middle of the area, the zone, that is

A direct Mercator graticule is based on a projection that is: "cylindrical" An Oblique Mercator projection is used specifically to produce: a) plotting charts in equatorial regions b) radio navigational charts in equatorial regions c) topographical maps of large east/west extent d) charts of the great circle route between two points <-- Correct The animation linked to the illustration in Figure 2.22.3, below, shows a series of 60 Transverse Mercator projections that form the 60 zones of the UTM system. Each zone is based upon a unique Transverse Mercator map projection that minimizes distortion within that zone. Zones are numbered 1 to 60 eastward from the international date line.

Beautifully detailed portolan charts present historians with a puzzle: How were they made? Many modern maps solve this problem by using so-called Mercator the equator and the lines of longitude that converge at the Earth's poles into a  portolan chart with an oblique Mercator projection.
