2020和2022年青藏高原30 m分辨率不透水面覆盖数据集
30 m resolution impervious surface covering dataset for the Qinghai-Xizang Plateau in 2020 and 2022
摘要
Abstract
The Qinghai-Xizang Plateau 30 m resolution impervious surface covering dataset was derived from Landsat 8 annual median synthetic data,2 m high-resolution data,and topographic data using a multi-feature fusion model.Impervious surface samples were initially constructed using a stratified sampling method with geomatics knowledge constraints.A fuzzy category training strategy was employed in the model training process.The impervious surface covering datasets for 2020 and 2022 exhibited a precision of 99.69％and 98.84％,respectively,with a recall of 84.40％and 79.40％.Additionally,the F1-Score was 0.91408 and 0.88059,respectively.These results were saved in GeoTiff format,providing crucial data support for research on ecological environmental protection,urbanization monitoring,and human activities in the Qinghai-Xizang Plateau.关键词
