主　　题：Wuchang Lake Sentinel-2 Landsat 8 endangered bird species 

摘      要：As part of the Dragon 4 project,the water extents of Wuchang and Shengjin lakes have been extracted from Sentinel-2 time series,using all exploitable images since the beginning of the acquisitions in *** aim of the study is to assess the capability of the Sentinel-2 constellation and Landsat 8 over the Anhui region,especially the high temporal resolution.A total of 32 dates have been used and 10 Landsat 8 images(Libra)have been added to try to reduce the temporal gaps in the Sentinel-2 acquisitions caused by cloudy *** were done using a SERTIT-ICube automatized routine based on a supervised Maximum Likelihood *** extractions allow to recreate the dynamic of the two lakes and show the drought and wet *** the 3 years interval,the surface peaks in July 2016 for both *** lowest level appears at two different dates for each lake;in January 2018 for Wuchang,in February 2017 for *** Lake surface area appears to be more variable than Shengjin Lake,with many local maximum and minimum between the end of 2017 and April *** the case of Wuchang Lake,floating vegetation is a problem for automatic water surface area *** lake is covered by vegetation during long periods of time and the water below can’t be detected by automatic radiometric ***,Sentinel-2 stays a pertinent and powerful tool for hydrological monitoring of lakes confirming the expectation from the remote sensing wetland community before *** presence of NIR and SWIR bands induces a strong discrimination between water and other classes,and the systematic acquisitions create dense time series,making analysis more *** makes possible to sensor events occurring over short periods of *** to this a link can be done between endangered bird species,such as the Siberian Crane and the Lesser White-Fronted Goose and periodically flooded *** midterm results illustrated the pertinence and powerful of
