搭载于美国航空航天局(NASA)Tera卫星上的ASTER传感器具有从太空测量来自地球表面的多光谱热红外(TIR)辐射的能力.基于地球表面典型岩石类型的热红外光谱特征分析,我们建立了几种探测硅质岩、碳酸岩及硅酸盐岩中全岩SiO2含量的指数.我们将这些指数应用于帕米尔东北缘地区的 ASTER多光谱热红外图像数据,并将遥感解译分析结果与该区已发表的地质资料和野外调查结果进行比较结果表明,ASTER热红外遥感方法具有很大的应用潜力:它可以有效地提供整个帕米尔地区的主要地质信息.这是常规的地质调查方法无法完成的,因为该区的野外地质调查受到自然地理条件等因素的限制.
ASTER sensors mounted on NASA’s Tera satellite have the ability to measure multispectral infrared (TIR) radiation from the Earth’s surface from space, based on the thermal infrared spectroscopy characterization of typical rock types on the Earth’s surface Several indices for detecting SiO2 in whole rock in siliceous rocks, carbonate rocks and silicate rocks, we apply these indices to ASTER multi-spectral thermal infrared image data in the northeast Pamir region, and compare the remote sensing interpretation results with A comparison of published geological data and field findings in this area shows that the ASTER thermal infrared remote sensing method has great potential for application: it can effectively provide the main geological information throughout the Pamir region, which is why conventional geological survey methods can not Completed, because the area’s field geological survey by the physical and geographical conditions and other factors.
