| Abstract | The need for a new Slovak mapping projection The GPS reference system and the Slovak grid have been derived by different methods, on different datums, within different reference frames and with positions expressed on different coordinate systems. Therefore, GPS positions are not directly compatible with the Slovak grid and they must be transformed in order to relate correctly. The accuracy of the GPS coordinates would be decreased by the datum transformation depending on many factors, the main one being the local deformation of S-JTSK network. ETRS-89 positions derived using Slovak Kinematic Terrestrial Reference Frame 2001 are threedimensional, in the form of geographical coordinates. To calculate grid coordinates from the latitude and longitude requires that a map projection is associated with the new geodetic framework, thus providing two-dimensional grid coordinates that can be shown on a map. However, the grid coordinate obtained depends on used ellipsoid and projection parameters ETRS-89 relates to the GRS80 ellipsoid, the Bessel ellipsoid used by the Slovak grid. The new projections need to be associated with the accepted global reference ellipsoid, GRS80, and the associated coordinate system, ETRS-89. |
