Mercator Projection

As a result data north of about 851 and south of about -851 latitude can not be shown and has been cut off. This produces a fast approximation to the truer but heavier elliptical projection where the Earth would be projected on a more accurate ellipsoid flattened on poles.

The size of the grid depends on the map zoom level.

Mercator projection. Mercator projection a map projection introduced by Flemish cartographer Gerardus Mercator in 1569. At the next higher zoom level the world is. X λ π.

Explaining the sacrifices made to convert the earths spherical surface into a. The map area of such maps is a square with x and y coordiates both between -2003750834 and 2003750834 meters. X a λ y a 2 ln 1 sin φ 1 sin φ.

This map projection is practical for nautical applications due to its ability to represent lines of constant course known as rhumb lines as straight segments that conserve the angles with the meridians. The Mercator projection is a useful navigation tool as a straight line on a Mercator map indicates a straight course but it is not a practical world map because of distortion of scale near the poles. The basic Mercator projection formula is this.

Die Projektion ist unter mehreren Namen bekannt. Gauß konform oder Gauß-Krüger in Europa. A great tool for educators.

Die Mercator-Projektion ist eine winkeltreue Zylinderkartenprojektion die ursprünglich zum Darstellen genauer Kompasspeilungen für die Seefahrt erstellt wurde. You may be surprised at what you find. The plane represents the globe as a square grid of map tiles.

Sie wurde 1569 von Gerardus Mercator vorgestellt. Drag and drop countries around the map to compare their relative size. Die Mercator-Projektion wurde ursprünglich erstellt um bei Seereisen die genaue Kompassrichtung anzuzeigen.

The Mercator projection is a map projection that was widely used for navigation since loxodromes are straight lines although great circles are curved. The following equations place the x-axis of the projection on the equator and the y. Mercator EPSG 3857 Most tiled web maps such as the standard OSM maps and Google Maps use this Mercator projection.

Darüber hinaus werden lokale Formen genau und eindeutig definiert. Displaystyle x-alambda qquad yfrac. Ihre Gültigkeit hat die sogenannte Mercator-Projektion bis heute nicht verloren.

In Cartography any map projection of the terrestrial sphere done on the surface of a cylinder unrolled as a plane is known as a cylindrical projection. Der ellipsoidale transversale Mercator in den USA. λ φ - x-1 1 y -1 1 In this formula.

Is Greenland really as big as all of Africa. Die ellipsoide Form der transversalen Mercator-Projektion wurde 1825 von Carl Friedrich Gauss entwickelt und 1912 von Johann Heinrich Louis Krüger weiter analysiert. Gleichzeitig prägte sie aber auch die Vorstellung die sich Menschen von der Erde machen.

Sie ist eine wesentliche Grundlage für digitale auf Satelliten basierende GPS-Karten. Modeled and animated by Grafonaut. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer - Gerardus Mercator - in 1569.

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Y lntanπ4 φ2 π. Video as part of a course by Emarin Norway.

Now you may ask what a cylindrical map projection is. At the lowest zoom level the world is contained in one map tile. Eine weitere Funktion dieser Projektion ist dass alle lokalen Formen bei einem unendlichen Maßstab genau und richtig definiert sind.

The tangent transverse Mercator projection defines the coordinates xy in terms of λ and φ by the transformation formulae of the tangent Normal Mercator projection. Spherical Pseudo-Mercator projection Most of OSM including the main tiling system uses a Pseudo-Mercator projection where the Earth is modelized as if it was a perfect a sphere.
