Hyperspectral remote sensing application in geological mapping in northeast Qinghai-Tibet Plateau

In this paper, we introduce hyperspectral remote sensing with the focus on several key techniques including dimension reduction, image de-noise, classification, and so on. Then, we describe an application of hyperspectral remote sensing for geological mapping in the northeastern Qinghai-Tibet Plateau. Because of the complexity of geological environment, the application of hyperspectral remote sensing for geological mapping can't simply rely on field spectrum measuring. We recommend a combined use of the field-based spectrum measurements and manually select samples would be the most appropriate for accurate geological mapping. © 2009 SPIE.
