This paper aims at presenting geodetic studies that are in close connection with landslide modelling and must be used for continuously monitoring the areas affected by geomorphological hazards. Although sometimes the geodesist's contribution to certain projects for landslide monitoring meant to develop early-warning-systems or risk maps is not adequately appreciated as stated in FIG Working Group (2006) 20 and he is only seen as supplier of measured geometric data, the geodesist has a significant contribution through his abilities regarding the modelling of dynamic systems, like strategic constructions (dams, tall buildings etc.) or landslides and data interpretation The study of how an objective affected by landslides behaves in time implies geodetic measurements performed at pre-set time intervals using state of the art technologies, which allow processing and review of data thus obtained in a three-dimensional system. Moreover, the goal is to set the stage for the shaping and optimization of monitoring networks by choosing the optimal research methods to be used.
