摘要

Based on the images taken by Sentinel-1A before and after rainstorm in Poyang Lake in June 2017,the expansion range of water area in the lake area was extracted quickly and effectively using the threshold method and vector superposition method.It is proved that the method is simple and feasible,which can provide reference for the research and utilization of Sentinel-1 satellite data in the assessment of flood disaster.
