成像光谱矿物填图精度兼与矿物丰度关系初探

Preliminary study on the relationship between mineral mapping precision and mineral abundance on imaging spectrometry

成像光谱遥感技术在岩石矿物识别和矿物填图方面发挥着越来越大作用,而成像光谱矿物填图的精度问题一直是研究的焦点。文章利用高光谱数据HyMap对新疆东天山地区的矿物填图结果,通过引入矿物填绘分布强度的概念,探索性的分析了成像光谱矿物填图与填绘矿物丰度的关系。

Imaging spectrometry remote sensing technology has played a more and more important role in identifying rocks with minerals and mineral mapping. Whereas, the mineral mapping precision of imaging spectrometry is a studying focus all the time. Using the mineral mapping result of East Tianshan area in Xinjiang based on HyMap data, it has tried to analyze the relation between imaging spectrometry mineral mapping and abundance of mapping minerals through introducing the concept of distributing intensity for mineral mapping.
