A dataset of annual surface water distribution in the Yellow River Basin from 1986 to 2023

The dataset of surface water distribution in the Yellow River Basin from 1986 to 2023 was produced, including surface water frequency data (WBF) and surface water category data (SWC). By evaluating the accuracy of the water extraction results, the overall accuracy OA reached 97.60%, with a Kappa coefficient of 0.95.

The two sets of data produced in this study are both raster data, using the WGS84 geographic coordinate system with a spatial resolution of 30 meters. The file types are both *. tif files and the file naming format is YYYY. tif (YYYY is the corresponding year). The frequency data of surface water has band values ranging from 0 to 1 (floating-point type), and the band values of surface water category data are 0 (non water body), 1 (seasonal water body), and 2 (permanent water body).
