This paper deals with surveying activities in order to define the displacement of the Earth's crust, local displacements of the Earth's surface, and the displacement and deformation of constructed buildings. The determinations of horizontal movements in the terrestrial network, in the terrestrial altitude network and in the GNSS network are dealt with at two levels of accuracy. Geotechnical surveying activities are explained in the paper and demonstrated in the table. The paper Geodesy in geotechnics, published in Geodetski vestnik 54(1), and this paper present an integral whole.
