ANALYSIS OF LANDSLIDES THROUGH GEODETIC-TOPOGRAPHICAL METHODS AND 3D MODELING
The aim of the landslides study, located on the southern slope of the Cetățuie Hill (urban zone, Gruia neighbourhood, Cluj-Napoca City) is to create a geodetic-topographic plan and documentation that can be used specifically in planning and predicting erosion of slopes. In this study case was used the topographic documentation for hazard assessment of landslides. For the plan metrical and nivelitic surveying were used national geodetic network points of support supplemented with thickening points (due to work), in order to use them as starting and closing elements for determining the survey control In order to determine the points of land used for the survey network, a Pentax R – 322NX Total Station was used. Creating a 3D model from the data collected in the field was done using TopoLT and Surfer.
