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. Modeled and animated by Grafonaut.

Mercator projection type of map projection introduced in 1569 by Gerardus Mercator.

Mercator projection. However the Web Mercator uses the spherical formulas at all scales whereas large-scale Mercator maps normally use the ellipsoidal form of the projection. Most people can access a Mercator projection without charge. Der ellipsoidale transversale Mercator in den USA.
Die Parameter Mittelmeridian und Breitengrad des. The discrepancy is imperceptible at the global scale but causes maps of local areas to deviate slightly from true ellipsoidal Mercator. Mercator is a conformal cylindrical map projection that was originally created to display accurate compass bearings for sea travel.
Now you may ask what a cylindrical map projection is. When you go online to check your directions or look up data about a specific city then you are using an updated version of this planetary representation. Ihre Gültigkeit hat die sogenannte Mercator-Projektion bis heute nicht verloren.
Mercator-ProjektionHilfe ArcGIS for Desktop. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. You may be surprised at what you find.
The following equations place the x-axis of the projection on the equator and the y-axis at longitude where is the longitude and is the latitude. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer - Gerardus Mercator - in 1569. Darüber hinaus werden lokale Formen genau und eindeutig definiert.
Mercator projection became the standard projection for. Drag and drop countries around the map to compare their relative size. Explaining the sacrifices made to convert the earths spherical surface into a.
A great tool for educators. Mercator EPSG 3857 Most tiled web maps such as the standard OSM maps and Google Maps use this Mercator projection. The average person uses a Mercator projection almost all of the time even if they do not realize that is what theyre doing.
Die transversale Mercator-Projektion ist eine allgemeine Projektion die von den UTM-Koordinatensystemen und einigen State-Plane-Koordinatensystemen verwendet wird. 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.
Dennoch wurden weiterhin häufig die überlieferten Karten mit der Mercator-Projektion genutzt. Certain Web mapping and visualisation applications. Video as part of a course by Emarin Norway.
The Mercator projection is a map projection that was widely used for navigation since loxodromes are straight lines although great circles are curved. Sie ist eine wesentliche Grundlage für digitale auf Satelliten basierende GPS-Karten. If you want a paper map then this tangible.
In seinem umfangreichen Atlas von 1595 hat er sie daher nicht verwendet. Uses spherical development of ellipsoidal coordinates. Web Mercator is a slight variant of the Mercator projection one used primarily in Web-based mapping programs.
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. Gauß konform oder Gauß-Krüger in Europa. The meridians are equally spaced parallel vertical lines and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as.
As a result data north of about 851 and south of about -851 latitude can not be shown and has been cut off. Although the linear scale is equal in all directions around any point thus preserving the angles and the shapes of small objects the Mercator projection. It uses the same formulas as the standard Mercator as used for small-scale maps.
Mercator selbst hatte klargestellt dass seine 1569 ausdrücklich und ausschließlich ad usum navigantium zum Gebrauch der Seefahrer veröffentlichte Projektion sich für geographische Kartenwerke nicht eignete. Is Greenland really as big as all of Africa. Transverse Mercator NGA 2014 ist eine Variante dieser Projektion die noch den zusätzlichen Vorteil hat dass ein größerer Teil der Welt angezeigt werden kann.
The map area of such maps is a square with x and y coordiates both between -2003750834 and 2003750834 meters. Die Projektion ist unter mehreren Namen bekannt. It is often described as a cylindrical projection but it must be derived mathematically.
An additional feature of this projection is that all local shapes are accurate and correctly defined at infinitesimal scale. EPSG3857 Projected coordinate system for World between 8506S and 8506N. Die Mercator-Projektion wurde ursprünglich erstellt um bei Seereisen die genaue Kompassrichtung anzuzeigen.
Relative to WGS 84 World Mercator CRS code 3395 errors of 07 percent in scale and differences in northing of up to 43km in the map equivalent to 21km on the ground may arise.
