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:
Geological, geodynamical and hydrological research in Zagreb area resulted in several spatial data of different lineage, coordinate systems and resolution. The goal of this paper is the gathering of data in a unique geotechnical information system, which will br the basis for further analysis. We are using ArcGIS modules for spatial and geostatistical analysis. Geotechnical information systems can be used to prevent, mitigate and alleviate damage caused by the natural disasters such as eartquakes and landslides. However, the geotechnical data bases have not been utilized extensively. Examples of using the data bases this chapter for seismic hazards assessment, planning for new structures, ground water hydrology, disaster mitigation systems of gas pipelines, and infrastructure management systems are presented.

Opis:
In October 2000, the Faculty of Geodesy, University of Zagreb, with the support o German Federal Agency for Cartography and Geodesy (BKG) and Croatian State Geodetic Administration, established two permanent GPS-stations: one in Dubrovnik and another one in Osijek. The stations became the part of large global network International GPS Service for Geodynamics (IGS), ie. the part of EUREF/Permanent project. This paper describes the background for the choice of locations, stabilization and precise measurements of local GPS-networks that connected the stations with EUREF/CROREF points nearby. The problems in the maintenance of the stations have been described as welI. A view on the perspective of permanent GPS-services in Croatia is given, too.

Spatial Information System
Opis:
'Land' plays multidimensional role in maintaining many global processes, therefore sustainable planning and management of land resources is an important issue at the global forum. The process of land resource planning and associated decision-making invariably involves multiple objectives, multiple criteria and multiple social interests and preferences. Such complexity necessitates a systematic approach to the decision-making process to accommodate the multiplicity and multi dimensionalities of the problem to improve the reasonability of decisions and to justify the actions to be taken. The objective of this study is to perform a preliminary assessment of the landslide susceptibility for enviroment protection in the City of Zagreb. A geographic information system (GIS) database was compiled based on data from topographical and geological maps. Weight of evidence, analytic hierarchy process (AHP), and fuzzy logic methods, as well as hybrid methods, were used to establish the rating of classed for each factor, weigting for the factors, and to combine multiple factor layers into landslide-susceptibility maps. The results recognize relative weights between the influential factors and promote the real efficiency on City of Zagreb hillsides disaster can be important references for establishing the evaluation model.

Opis:
Faculty of Geodesy, University of Zagreb, recently acquired the latest technology for performing the precise hydrographic surveying. The equipment consists of ATLAS DESO 14 surveying echosounder with two transducers: one with high frequency (210 kHz) and second with low frequency (33 kHz). The position of the transducer is determined with Real Time Kinematics GPS pair of Trimble R8 receivers. 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. The results of the application of this method in measuring two lakes in the National Park Plitvice Lakes are shown in this paper.

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.
