Abstract In this paper, remote sensing monitoring technique and its application for waterlogging disaster in Zhejiang Province is introduced. It indicated that, by means of computer processing and analysing the NOAA-AVHRR data,large spope waterlogging disaster can be monitored, and the scope level and area of waterlogging disaster can be precisely, quickly, objectively estimated. Then, the damage image, numerical chart and damage report are promptlyprovided to leadership or policymaker as scientific basis for fighting and rescuing the disaster.
