REMOTE-SENSING AND GEOGRAPHIC INFORMATION-SYSTEMS

Remote sensing and Geographic Information Systems (GIS) play a fundame ntal role in hydrological applications. In this paper the most commonl y used processing procedures for remotely sensed data in particular im age processing techniques - and the capabilities of GIS technologies a re presented. The aim of this paper is to show the merit of a combinat ion of these tools with hydrological models. An important aspect herei n is the use of image processing systems, GIS, database management sys tems (DBMS) and hydrological models in a integrated analysis system.
