摘　　要：分别使用多光谱Aster数据和HyMap航空高光谱数据对新疆若羌的研究区进行矿物填图,并通过实地考察与样本光谱检测分析将验证结果与提取结果进行准确度评价。结果表明,两种遥感数据的提取结果吻合度较高,高光谱HyMap数据无论在填图精度还是在准确度方面都远远优于多光谱Aster数据,填图结果可以为新疆若羌的矿产勘探提供数据参考。This paper used Aster multi-spectral data and HyMap Airborne Hyperspectral Data to carry out mineral mapping in the study area of Ruoqiang,Xinjiang.The correctness of the verification results and the extraction results was evaluated through field investigation and sample spectral analysis.The results show that the two kinds of remote sensing data extraction results are generally coincident,hyperspectral HyMap data are far superior in terms of mapping precision or accuracy over multispectral Aster data,the mapping results can provide data reference for mineral exploration in Ruoqiang,Xinjiang.
