资源一号02D卫星高光谱数据地质调查应用评价

Application Evaluation of ZY-1-02D Satellite Hyperspectral Data in Geological Survey

资源一号02D卫星是我国首颗民用高光谱业务卫星,可有效获取400~2500nm范围166个谱段的高光谱数据。为了更好地了解其在地质调查工作中的应用效果,文章利用资源一号02D高光谱数据,在哈密遥感地质试验场地区主要对其在岩性-构造信息识别、矿物信息提取等方面开展了应用评价。应用结果表明:资源一号02D卫星高光谱数据,不仅能够准确识别研究区地表矿物信息,也可清晰地显示和区分区内不同地层、岩体、构造等地质体,其空间展布特征一目了然,资源一号02D高光谱数据可为今后高光谱遥感地质调查工作提供强有力的数据支撑。

ZY-1-02D satellite is the first commercial hyperspectral operational satellite in China.It can effectively obtain 166 spectral bands of hyperspectral data in the range of 400~2500nm.In order to better understand its application effect in geological survey,this paper uses the ZY-1-02D satellite hyperspectral data in Hami remote sensing geological test site area to evaluate its application in lithology structure information identification and mineral information extraction.Results show that:ZY-1-02D satellite hyperspectral data can not only accurately identify the surface mineral information of the study area,but also clearly display the geological bodies of different strata,rocks and structures in the area.The spatial distribution characteristics are clear at a glance.ZY-1-02D satellite hyperspectral data can provide strong data support for the future hyperspectral remote sensing geological survey.
