The data obtained in the precise levelling performed by the Przedsiębiorstwo Geologiczno - Geodezyjne ,"Geoprojekt - Gdańsk", as well as the material analyses, indicate the need to conduct further observations of dislocations in the Main and Old City of Gdańsk in the next years, in intervals of at least six months, controlled by independent fundamental altitude points. The results of GPS static measurements at reference and check points, conducted during the first year, should be taken as reference values for the measurements conducted in subsequent years. The differences in the results from consecutive years will indicate the existence of vertical and horizontal movements of the earth's surface, where the City of Gdansk is situated. The check points, stabilised with fundamental altitude points, will be used to monitor the settlement of historical tenement houses in Gdańsk. Measurement of horizontal and vertical deformations of the earth surface in the areas where valuable objects of our cultural heritage are situated will make it possible to detect potential threats and to take action to prevent considerable damage.
