2019年外蒙西乌尔特示范区高光谱地表矿物信息分布产品数据集

该数据集为境外示范区外蒙西乌尔特地区地表矿物信息分布产品。利用高分五号高光谱数据在示范区共识别褐铁矿、方解石、高/中/低绢云母、绿泥/绿帘石、高岭石、叶腊石等矿物信息，并经影像光谱检查和野外实测光谱验证，境内示范区矿物信息提取精度为88.51%。

This dataset is a surface mineral information distribution product for the West Urt region in Outer Mongolia, an overseas demonstration zone. Hyperspectral data from the Gaofen-5 Satellite was utilized to identify mineral information including limonite, calcite, high-, medium-, and low-grade sericite, chlorite/epidote, kaolinite, pyrophyllite and other minerals within this demonstration zone. Following verification via image spectral inspection and field-measured spectral validation, the extraction accuracy of mineral information within this demonstration zone reached 88.51%.
