Abstract

Global land cover product and extraction technology with remote sensing images are the common methods to obtain the information of surface water. This paper selects the GLC_FCS30-2020 (GLC-2020) product and two results of water extraction by Sentinel-1A SAR images on different date and analyzes the consistence and accuracies of them. Verifying by the experiments, the consistence between the results of GLC-2020 and SAR method is higher than 80%, and the values of UA and PA of them are all more than 90% and 85%, respectively. The three results of surface water extraction all meet the needs of general applications. Considering the convenience and continuity, GLC-2020 is adopted in more applications and the SAR method is more suitable for time series observation.
