资源简介：
The accurate extraction of surface water is an important basis for studying the changes of quality and quantity for surface water, Hainan Island is generally rich in surface water resources, with a large number of small reservoirs and rivers. Therefore, this product takes lakes and reservoirs with an area of more than 1km2 and rivers with a width of more than 100m in Hainan Province as the research area, uses the surface reflectance data of sentinel 2, and uses an algorithm combining NDWI and OTUS automatic threshold segmentation to extract water bodies in Hainan Province. This data set can provide basic data support for the subsequent inversion of water quality parameters in Hainan Province.
