2017 water products based on sentinel-2 in Sanjiangyuan, Puhe and Yukon River Basins

The data of this study is mainly based on Google Earth Engine big data cloud processing platform. Sentinel-2 of The Three River Headwater region, Pul and Yukon River Basins in 2017 is selected as the basic data, STRM-DEM and Global Surface Water are used as auxiliary data. AWEIn,AWEIs,WI2015,MNDWI,NDWI and other index threshold extraction are selected to obtain seasonal water body and permanent water body according to annual water frequency(spatial resolution 10m). This water data product provides effective basic data for high spatial-temporal resolution water body change and permafrost hydrological analysis.

Data file naming and use method

This data product is a grid file (. TIF), which can be opened with ArcGIS version 10.0 or envi version 5.0 or above. Grid values of 0, 1, 2 and 3 represent empty data, non water body, seasonal water body and permanent water body in turn. The naming format is: drainage abbreviation_2017, The Three River Headwater region (SJY), Pul River Basins (SIB), Yukon River Basins (Yuk) drainage basin, using WGS84 projection.
