摘要：
The coastal floods induced by hurricane storm surge are frequent, costly, and deadly hazards. Accurately and quickly estimating the spatial extent of floods is highly important for relief and rescue operations. In this study, we present an approach to estimate the extent of large-scale coastal floods using AMSR-E data through mixed-pixel linear decomposition. Furthermore, based on the water fraction, using the physical characteristics of water inundation that always proceed from the lowest to the highest elevation points in a basin, the flood map derived from the coarse-resolution AMSR-E measurements was extrapolated to a higher spatial resolution of 100 meters using DEM data. The comparison result with 250-m MODIS image showed the effectiveness of the super-resolution mapping method.
