Sažetak
In this paper application of contemporary geodetic methods for determination of geodynamic activities is presented. Specially stabilized pillars of Geodynamic Network of the City of Zagreb and newly founded geodynamic points in tectonically most active areas create baseline for investigations of tectonic movements and related seismic activity. In the foothills of mount Sljeme, real estate heaven of Zagreb area, on a larger number of locations landslides occur. It is assumed that some of the slides occur due to tectonic activities. GPS technology is used for monitoring of movements combined with advanced processing of GPS measurements by Kalman filtering. Precise satellite positioning yielded the accuracy that was by an order of magnitude better than the magnitude of movements. Another modern geodetic method can be applied to landslide monitoring, laser scanning. In recent years, terrestrial laser scanning is used in various fields including the monitoring of deformations. The greatest advantage of laser scanning as opposed to the classical method is the possibility of analyzing the surface in its entirety. Due to the high criteria of accuracy and precision in monitoring the deformation of these types requires an independent calibration of measuring instruments. Likewise, special attention should be given to the geo-referencing point clouds with a particular perspective to the process of analysis that might detect deformation and also that it is separated from the measurements noise. Data collected by laser scanners can be used for continuous visualization of the landslides, but also for monitoring the deformation of objects located in the landslide area. Results of geodetic measurements are combined with geologic measurements and results of seismic activity studies in order to give more detailed and more accurate picture of the current situation in the tectonically very active micro location around St. Mary's church in Granesina. Synergy of contemporary geodetic methods of determination of geodynamic movements with geologic measurements and interpretation of movements is applied to monitoring of local tectonically caused landslides
