摘要
高分五号卫星是我国唯一一颗具备全球高光谱观测能力的卫星,可以获取从390nm到2 500nm 330个谱段的高光谱数据。为了更好了解卫星在地质矿产调查工作中的应用,利用高分五号卫星高光谱数据从数据处理、地质构造信息提取、岩性-构造信息的识别等方面对甘肃柳园地区进行了遥感地质调查应用评价。结果表明:高分五号卫星高光谱数据尤其是信息增强后的数据,能有效划分不同地质单元、识别地质构造空间展布特征,为地质矿产调查和评价工作提供强有力的数据支撑。
GF-5satellite is the only satellite with global hyperspectral observation capability in China.It can obtain 330spectral bands from 390to 2 500nm.In order to better understand the application of satellite in geological and mineral survey,this paper uses GF-5satellite hyperspectral data to carry out remote sensing geological survey application evaluation in Liuyuan area,Gansu province,and evaluates the outcome,such as data processing,geological structure information extraction,lithology-structure information recognition and other aspects.The results show that the GF-5satellite hyperspectral data,especially the enhanced data,can effectively divide different geological units,identify the spatial distribution characteristics of geological structures,and provide strong data support for geological and mineral investigation and evaluation.
