The Committee for State Control and Protection of Historical and Cultural Landmarks of St.-Petersburg has supported
the researches, directed on an estimation of efficiency of satellite radar differential interferometry (SRDI)
application on a cultural heritage protection. Within this researches, maps of surface deformations for the period of
the last 10 years were compiled on the base of ERS-1,2 and ALOS(PALSAR) satellite radar data by using techniques
of SRDI and satellite radar interferometry of permanent scatters (SRI PS). The errors of vertical deformations
were estimated on the bases of repeated radar satellite surveys. The satellite data were compiled with the results of
standard repeated leveling for the period of 1980-2003. It was observed the periodic and episodic oscillations of land
surface with amplitude of few tenths of millimeters. Few hypotheses were built to explain such vertical land surface
movements. Two of them were verified by mathematical simulations. As the result, the basic principles of Saint-
Petersburg territory zoning according the risk of historical building deformation were suggested.
