USGS Spectral Library Version 7 是美国地质调查局(USGS)利用实验室内、野外地面和机载光谱仪采集的一系列光谱的集合形成的光谱库。从名字也可以看出,目前最新的是v7版本。该光谱库覆盖的光谱范围十分宽,波长覆盖从紫外到远红外光谱,具体数字来说,从0.2 μm 到200 μm 。实验室内测量的样品包括特定的矿物、植物...
USGS Spectral Library是由美国地质调查局光谱分析实验室和地质、地球物理、地球化学科学中心联合编纂的综合性光谱数据库。该数据库通过实验室、野外和航空光谱仪测量多种物质的反射率波谱，并收集X射线衍射、电子探针等分析技术数据。库内光谱覆盖紫外到远红外波长范围，样品包括纯净矿物、岩石、土壤、植物、微...

Introduction We have assembled a digital reflectance spectral library that covers the wavelength range from the ultraviolet to far infrared along with sample documentation. The library includes samples of minerals, rocks, soils, physically constructed as well as mathematically computed mixtures, plants, ve...
是美国 USGS 研究人员在实验室对数以百计的地物及矿物进行光谱反射率测量而后并编制了光谱谱库。该库用来鉴 定遥感图像中的地物。下面是这些地物和矿物的光谱曲线图,具体数据在原网址里,下面有链接,可以自己下载。 (The UV to mid-infrared 0.2-150 micron library (splib06) contains over 1300 spectra ...

We also present the expert system rules that describe which diagnostic spectral features are used in the decision making process for a set of spectra of minerals and other common materials. We demonstrate the applications of Tetracorder to identify and map surface minerals, to detect sources of ...
Previous studies overestimated calcite abundance as a result of these spectral overlaps. The use of a reference library containing synthetic mixtures of the three minerals in varying proportions was found to simplify the task of identifying these minerals when used in conjunction with a rule-based ...
