摘要

Within the graduation thesis we established a geodetic network in local coordinate system in the area ofudthe town Radovljica. We stabilized 31 points on which we observed horizontal angles, zenith distancesudand slope distances with the instrument Leica TS30. Fieldwork also included height measurements withudgeometric levelling method. Measured quantities were then processed and prepared for horizontal andudheight adjustments. We transformed the adjusted network coordinates in local coordinate system withudthe 7 parametric transformation into the national coordinate system D96/TM and calculated the precisionudof the transformed coordinates. The transformation was done with the calculation of 7 parameters basedudon 8 tie points which were given in the national coordinate system. Established geodetic network willudbe used in further research for the purpose of analysing the quality of airborne laser scanning pointudclouds in this area.
