摘要
高光谱遥感作为全新的遥感技术,在新疆目前处于探索研究阶段.本文阐述了新疆阿尔金地区Hyperion高光谱数据在矿物填图中的数据处理和应用研究.EO-1Hyperion高光谱遥感影像的波谱范围为400～2500nm,提供了大量的地表矿物信息,特别是为2000～2500nm波谱范围提供了羟基矿物、碳酸盐类矿物和热液改造矿物的波谱特征,采用MNF、PPI、N维散度分析、波谱分析和MTMF矿物填图的波谱分析方法,最终完成矿物填图,为高光谱遥感技术在新疆遥感地质矿物填图的应用提供技术支撑.
The Hypersperctral technique was placed in explore stage in Xinjiang.The Hyperion was researched in Xinjiang East KunLun mountain region.EO-1 Hyperion Hyperspectral data coverage from the 400 to 2 500 nm spectral range , provides abundant information about many important Earth-surface minerals.In particular, the 2 000 to 2 500 nm spectral range covers spectral features of hydroxyl-bearing minerals,sulfates, and carbonates common to many geologic units and hydrothermal alteration assemblages.A serious of spectral analysis methods of minerals and rocks, such as MNF, PPI, N-Dimensional Visualization, Spectral Analyst, and Spectral classification technique were used.Finally, the mineral mapping was finished.This Hypersperctral technique provide a good support for mineral mapping in Xinjiang.
