利用机载的可见光、近红外及短波红外成像光谱(HyMap)数据,对新疆哈密地区岩矿信息识别方法进行研究。基于方解石、绿泥石和绢云母3种常见蚀变矿物的光谱特征,在遥感数据定标和反射率图像转换的基础上,应用光谱角度模型(SAM)分类法进行自动匹配识别和信息提取。通过掩膜技术进行方解石、绿泥石和绢云母矿物填图,并结合实验室光谱数据库光谱进行了验证。 更多还原

【Abstract】 The study of mineral information reorganization method was carried out by means of the airborne visible light and near infrared and short-wave infrared imaging spectrometry (HyMap) data from Hami area of Xinjiang. By analyzing spectral features of three kinds of familiar altered minerals (calcite, chlorite and muscovite) and using the calibration of the remote sensing data and spectral reflectance retrieval, the authors employed spectral angle mapper (SAM) to extract mineral information from the... 更多还原
