高光谱分辨率遥感在地质应用中的关键技术及前景

Key techniques and prospects of hyperspectral remote sensing in geological application

遥感技术应用于地质中的目的之一是分辨和识别出不同的岩石和矿物等地质体。宽波段遥感只能分辨不同岩石类型,而难以识别含不同成分的岩石和矿物。高光谱分辨率遥感则可通过诊断性光谱特征对岩石或矿物成分及结构进行识别。通过对高光谱分辨率遥感应用于地质中的关键技术进行分析,对未来高光谱分辨率遥感在地质中的应用进行了预测。

One of the aims of RS application in geology is to identify accurately various rocks and minerals. Conventional multispectral RS can only distinguish rocks. It is difficult to identify various rocks and minerals which contain different components. With hyperspectral RS, rocks and minerals can be identified from the corresponding diagnostic spectral features. This paper provides an analysis on key techniques of the hyperspectral RS application in geology.
