Ten years of local water resource management : Integrating satellite remote sensing and geographical information systems

On 2002, a novel initiative was undertaken by the local water administration of Catalonia (the Agencia Catalana de l'Aigua) and the Universitat Autonoma de Barcelona, leading to a ten-year project where a high number of medium resolution satellite images (MODIS and Landsat) were integrated to the daily water management to improve decision making effectiveness. This paper describes the methodology followed in the successful application of remote sensing, as well as the main problems that had to be overcome during its execution. It also presents the products that have been calculated. These are integrated into the Agency's corporate GIS and immediately available via the intranet for the staff, and a selection is available on the Internet.
