Efficient flood monitoring based on RADARSAT-1 images data and information fusion with object-oriented technology

RADARSAT-1 delivers SAR imagery well suited fer monitoring and mapping of natural risks and hazards. Current methods are either based on human interpretation and are extremely time consuming, or they are automatic pixel based approaches, which have limitations for many applications. Here, we propose a new object-oriented strategy to monitor flooding using three RADARSAT-1 data sets with different acquisition times during a flood event shortly after the monsoon. A flexible strategy for the fusion of SAR and optical data is proposed. Using the synergy of data fusion enhances the usefulness of each individual sensor.
