Map projection for large scale maps. These plane and isogonal (conform) projection was described by the German mathematician Gauss and further developed by Krüger. Geometrically it is a Transversal Mercator projection, i.e. a tangent cylinder orthogonally imposed on the earth. The result of the projection is 120 stripes of each comprising 3 degree. Germany runs from zone 2 to 5. The distortion of distance is less than 12 cm referring to a distance of 1 km with a stripe width of ca. 100 km and can be neglected in most cases. This zone system is mapped by a rectangular coordinatesystem with the middle meridian as abscissa (Easting) and the equator as ordinate (Northing). In order to eliminate negative values while making statements of place to the west of the middle meridian the meridian comes up with the Easting value of 500.000. It is preceded with the key number of the main meridian. The Northing gets the (positive) values in the north or south diretction starting at the equator. Example: Northing = 5.902.863, 21m; Easting = 3.593.571, 20m means that the point is located 5.902.863, 21m to the north of the Equator laying in the third stripe (which means 9° East) and 93.571, 20m in the east of the middle meridian
