In my thesis, I present the analysis of transformations between ETRS89 and national
reference system. Analysis has been performed on a basis of network points and on digital
land register of the settlement Divača. Special emphasis has been dedicated to the
computation of transformation parameters from the trigonometric net, various polygon nets
and parameters calculated from detail points. The comparisons have been performed in
such way that the coordinates of detail points have been transformed with various
transformation parameters and compared with coordinates from the digital land register.
The thesis also contains the comparisons of coordinates of detail points, transformed with
various transformation parameters between them, a comparison of coordinates of detail
spots calculated from the original observation data and coordinates of detail points from
the digital land register, and a comparison of the results of coordinate points obtained by
the GPS measurements using different scenarios of connection to the VRS system and to
the private GPS reference station.
