EVALUATION OF A REMOTE SENSING BASED REGIONAL FLOOD/WATERLOG AND DROUGHT MONITORING MODEL UTILISING MULTI-SOURCE SATELLITE DATA SET INCLUDING ENVISAT DATA

Natural disasters connected to climatic extremities (flood, waterlog and drought) occurred more frequently in Hungary in the recent years. The Remote Sensing Centre of FÖMI (Budapest, Hungary) has started to develop a cost-effective satellite based model to monitor these natural disasters at regional level. The ESA–FÖMI Prodex-ENVISAT R&D project “Application development for the utilisation of ENVISAT data in remote sensing based regional flood/waterlog and drought monitoring (2000-2004)” aimed at the rapid and large scale monitoring of these disasters utilising available lowand medium resolution operational satellite data involving the new ENVISAT (specially MERIS and ASAR) data. This paper describes the results and shows examples about the achievements.
