Opis:
During last 10 years, geodesists from the Faculty of Geodesy, University of Zagreb, together with geologists and tectonicians established and performed a number of series of GPS-measurements on the Geodynamic Network of the City of Zagreb. The results of these campaigns emphasized the spots with higher level of geodynamic activity, resulting in damages on objects: houses, walls, churches. Therefore, the technology of threedimensional laser scanning has been employed in order to capture much more detailed picture of fast movements. In the first experimental phase of the project, only rapidly sliding areas are observed. The main hypothesis of proposed research is to check if the technology of precise laser scanning is able to produce comparable point clouds showing the movements of objects in the field. As an additional source of information, this research should contribute to the better understanding of the processes below the Earth surface.

Opis:
Recent advances in GPS-technology (GNSS) enable hydrographic surveyors to capture the topography of the bottom and the water surface with even more accuracy. Faculty of Geodesy, University of Zagreb, recently acquired the latest technology for performing the precise hydrographic surveying: Trimble R8 GNSS receiver that is going to be used with already used echo sounding equipment. The GSM signals are used for transmitting corrections from the base station to the rover. Thus, it is possible to use single-frequency DESO 14 for two-frequencies bathymetry through repeating the course of the vessel on exactly the same points with both transducers. It is expected that the new technology shall yield more accurate results and increase measurement speed, because the OTF times should be significantly shortened.

Opis:
Researchers from the Faculty of Geodesy, University of Zagreb, organized and performed various research activities within the project CERGOP2/Environment. The participation in both CEGRN campaigns was ensured with two epoch stations: Brusnik and Hvar. Activities related to the working package 10.4: International geodynamic test area Plitvice Lakes included several hydrographic measurements with the combination of GPS positioning and echosounder bathymetry. Repeated measurements with two frequencies yielded new insight about the sediments on the lake bottom. A structural map of the Lakes has been prepared, too. Geodynamic measurements has been performed on several special points. The foundation for future permanent station in the area of the Plitvice Lakes has been prepared.

Opis:
This paper summarises recent aetivities on merging the geodetic, geologic and neotectonic evidence of geodynamics in Croatian part of Dinnarides. The area of the City of Zagreb, which is the boundary zone of Eastern Alps, Dinnarides and Pannonian Basin is incIuded as well. It is shown here that the evidence for fractures of Eastern Adriatic differs from the previous hypotheses. This concIusion is derived from the results of various geodetic measurements: satellite positioning (GPS), astro-geodetic measurements of detlections of the vertical. These results 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 region of Dinnarides. Several GPS-campaigns performed in the City of Zagreb area are examined as well. Due to the proximity of Croatian capitol, special attention has been paid to the effects of possible hazard on construction code.
