Analysis of transformation models between the old and new national coordinate system for the creation of a survey plan

In the graduation thesis we will determine the relation between the new and old national coordinate system in Slovenia for the elaboration of the detailed survey plan. The survey plan has to be elaborated in the old national reference system but the measurement method used for the coordinate determination enables coordinates in the new one. For the establishment of the relation between the old and new national coordinate system we will deal with 3D-similarity transformations. In the beginning the brief theoretical presentation of individual coordinate systems (D48/GK, D96/TM and ETRS89) used in Slovenia is given, which is followed with the descriptions of basic relations between them. Following is the description of the internet application SiTraNet which is used in most of the calculations. The practical part is described next. Firstly we in short present the area under consideration and after we describe the methods of measurements for the coordinate determination. We will compare the transformation results with the parameters we calculated and the parameters that were found on SiTraNet application. The last part describes the practical procedure of the survey plan elaboration. The conclusion includes our findings at the end
