The aim of objects monitoring, carried out by a geodetic method, is to get any information about the casual and effect relationships which occur around the examined object. Application of a suitable measuring technique requires setting an advantageous network structure, which has to meet both the condition of measuring economy and assure the suitable characteristics of the determined parameters accuracy. The advantageous network structure may be obtained on the basis of selecting observations which contain the largest information content. The measurement results of the chosen network elements and the application of suitable methods of results processing enables to apply a correct identification of points of a reference system, and as a consequence, it also enables to define a correct model of the displacement. The process of setting an advantageous linear network structure on the basis of entropy of an observational system was presented in the paper.
