High resolution inland surface water dataset for the tundra and boreal in North America

High resolution inland surface water dataset for the tundra and boreal in North America

查看大图

The Water body dataset(WBD) data is important for hydrology research, matter and energy cycle research. The inland water inventory included water bodies of tundra and boreal forest in North America. The water extent was extracted from Sentinel-2 A/B multi-spectral with assistant of JRC yearly permanent water. Both water index and random forest methods were used to detect water. The water index extracted the loose water extent. Random forest extracted the more accurate water extent. And area, perimeter and shape index (SI) were provided in this dataset. The overall accuracy is 98%. It was established that about 6.7 million water bodies presented in tundra and boreal forest in North America, among witch 6 million small water bodies less than 0.1 km2 (90% of total water bodies) were included. And the inventory covered 0.12 km2 inland water, the average size, perimeter and SI of which were 0.12 km2, 1.01 km and 1.42.
数据使用方法

The water body dataset is stored in shapefile format. The file name is "WBI.shp".
