The system coordinates the global reverse (Universal Transverse Mercator coordinate system) that briefly yuty (UTM) ... somehow the system image that is mapped to, and goes from a Cartesian coordinate system two-dimensional direction of the specified position on the surface of the ground interest. This system somehow display position is horizontal and to display the position on the ground, independent of The it goes to work, but from several directions with the traditional method of geocoding (using latitude and longitude) the difference.

in the system yuty the Earth into 60 sections (wedges) is divided into each slice to the size of 6 degrees longitude.
