Abstract

Determination of the deformation of a geodetic network is an objective of the analysis of various geodetic deformation measurements. Deformation analysis is a step by step procedure, which in general begins with a global congruency test. If the coordinates of repeated measurement campaigns with its variance-covariance matrices and their datum are available, the question arises if congruency between different epochs exists. The analysis of the deformation field was performed in three dimensions. An alternative test procedure for detection of unstable points within the block assumed as stable beside the conventional method for congruency investigations is proposed and for both methods example solutions are given. The procedure is based on Similarity transformation. The benefit of both methods are discussed.
