| 摘 要： | ASTER数据在短波红外和热红外波段光谱信息明显优于ETM,使得在ASTER波段范围内能够更为详尽地刻画地物波谱,尤其是具有特征谱带的岩石和矿物.选择内蒙古东乌珠穆沁旗北部地区为工作区域,设计了用光谱角制图法提取矿化蚀变信息的技术方案.通过波段组合和增强处理,ASTER数据对含Fe-OH(如黄钾铁矾,含铁白云母)、Al-OH(如粘土类矿物、明矾石、绿泥石、绢云母)和Fe~(3+) (如褐铁矿,赤铁矿)3种类型蚀变信息的刻画能力明显比ETM更好.野外查证了提取结果的可靠性.

| Abstract: | The availability of spectral information in the shortwave infrared(SWIR) and thermal infrared(TIR) channels of the advanced spaceborne thermal emission and reflection radiometer(ASTER) is much better than that from Landsat ETM.It allows a detailed spectral characterization of land covers,particularly of those rocks and minerals with diagnostic spectra falling into the wavelength range of SWIR and TIR.The authors present a technical approach based on spectral angle mapper(SAM) for hydrothermal alternation in... |
