first What is a Gauss-Krüger-System (GK) system?
The Gauss-Krüger coordinate system is a Cartesian coordinate system. It allows sufficiently small areas of the globe with metric coordinates, ie Easting and Northing to locate, compliant.
The grid of geographical coordinates is divided into 3 ° wide meridian strips. Each meridian strip goes from the North to the South Pole so-called parallel to its central meridian. The central meridians Meridian adjacent strips are therefore 3 ° apart.
Each meridian strip is given a code number, which is derived from the number of degrees of the central meridian (0 °, 3 °, 6 ,...)
second Which units are to GK coordinates?
There are legal values and high values in the SI unit Meters are given.
third What is an ellipsoid, which is used in the GK system?
An ellipsoid is a higher-dimensional equivalent of an ellipse.
level sections of this body shall all ellipses or circles dar. The surface of the ellipsoid can be described mathematically, so that positions are specified by coordinates on the surface.
An ellipsoid that approximates most closely the surface of the whole earth is called a global geodetic datum. When GK is
system (also called Bessel 1841), the Bessel ellipsoid used. It was derived in 1841 by Friedrich Wilhelm Bessel. The data was large-scale Measurements.
4th Which Project is based on the Gauss-Krüger system? (Briefly explain)
The Gauss-Krüger system is based on a Transverse Mercator projection. Here, a cylinder is placed around the earth, it touches the equator. Transferring now all points on the cylinder and rolls them, one obtains a two-dimensional map of the earth. Since this is not angle-preserving, the map is distorted in North-South direction.
5th What is the difference between geographic and projected Cartesian coordinates?
Geographic coordinates are the coordinates of the position of a point on the Earth's surface. This is based on a graticule consisting of longitude and latitude. The starting points are the equator and the prime meridian.
Geographic coordinates are ALSO in the angular setting of points on the surface, starting from the equator, and uses the zero meridian.
Cartesian coordinates describing the position of a point in space. Reference system is a two-or three-axis orthogonal system, consisting of the axes x, y, (z).
6th Why are used in the GK system called meridian strip?
Man you tried distortions in the Mercator projection, north and south of the equator caused by so-called reduce meridian strip. The earth is here divided in 3 ° wide strips (strips Meridian). Each of these strips is a separate rectangular coordinate system dar. The x-axis coordinate system is related to the respective central meridian, which refers to the y-axis is always on the equator.
7th As you can see the number of the meridian strip used in a coordinate?
The code is the first in the coordinate, each principal meridian has its own identification number that is calculated by dividing by the number of degrees of the main meridian by 3 divided
