#### Abstract

The subject of present thesis was determining the horizontal displacements of St Anne’s Academic Church in Warsaw. For this purpose the survey network consisting of control points on the object, potential reference points and station marks of instrument was established in church neighbourhood. The measurements were performed on June 24, 2015 and October 26, 2015. The horizontal directions, slope distances and zenith angles were measured at three stations. The horizontal directions were measured in three series using the direction method. Moreover, at one station independent measurement of three horizontal angles was performed. The angles were measured in two series using the closing the horizon method. During both measurement cycles exactly the same observations in the same way were performed so that the method of observation differences could be used for data processing. In the next step results were preliminarily verified. The station adjustments of directions and horizontal angles were performed in order to determine the most likely values of observations and their accuracy characteristics. The measured slope distances were reduced to the common reference level. After that observations from both measurement cycles and observation differences were preliminarily adjusted. The adjustments were carried out using elastic datum defined on all potential reference points. At the end global and local tests were performed, which allowed authors to evaluate the correctness of performed measurements and detect possible gross errors. After verifying the observations the reference base was identified. Results from the preliminary adjustment of observation differences were used to perform identification of stable points. The identification was carried out based on the lengths of displacement vectors of the potential reference points and mean square errors of the lengths. As a result of this process, two reference bases were selected. After identification of reference points authors proceeded to determine the final horizontal displacement values of the points located on the temple. The values were computed twice, using each time different reference base, and then compared. At the end the graphic portrayal of the results was created and the final values of displacements were interpreted in geodetic manner.
