Ing. Bohuslav Veverka, DrSc., Czech Technical University, Faculty Of Civil Engineering, Department of Mapping and Cartography, 2 Ing. Klára Ambrožová ,Czech Technical University, Faculty Of Civil Engineering, Department of Mapping and Cartography, Prague, of the Prime Meridian for calculation of longitude in the eastern part of the Mediterranean it is not possible to determine the position of the Prime Meridian used for regional maps in Central Europe. studying positional accuracy of old maps we have to carefully investigate what Prime Meridian was used. of all parallels and meridians form nodal points the coordinates of which were determined by program Misys. 64 settlements on the map were selected for determination of graphical and After the calculation of Helmert's transformation key between system of plane coordinates of nodal points on old map and their coordinates in the S-JTSK system.	./cache/work_2i5ycua2prcbpg6fqgbuyeqnwy.pdf	./txt/work_2i5ycua2prcbpg6fqgbuyeqnwy.txt
