摘　　要：Hyperion高光谱数据在蚀变矿物填图方面已凸显其优越性,而在岩性识别方面大多仍在探讨中。通过应用Hyperion数据结合野外光谱采集,在研究区进行了岩性填图的试验研究。同时,叙述了野外采集光谱数据的过程,建立了野外实测光谱数据库,利用野外实测岩石光谱作为端元光谱进行SAM(Spectral Angle Match)光谱角岩性填图。这对于地质环境复杂地区的岩性填图工作具有一定的应用价值。Hyperion hyper-spectral data in altered mineral mapping has its advantage,but still is in discussing in lithology recognition.In this paper,lithology mapping used Hyperion data and field collected spectrum made as an experimental study in the research area.This paper described the process of spectral data collection in the field,established a field survey spectrum database,and used the rock spectrum of field survey as end-member spectra for SAM(Spectral Angle Match) spectral angle lithology mapping.For the lithology mapping works especially in complex geology environment like zhongyang mountains,it has certainly application value.
