Accuracy in mineral identification: image spectral and spatial resolutions and mineral spectral properties
Main Article Content
Abstract
Problems related to airborne hyperspectral image data are reviewed and the requirements for data analysis applied
to mineralogical (rocks and soils) interpretation are discussed. The variability of mineral spectral features, including
absorption position, shape and depth is considered and interpreted as due to chemical composition, grain size
effects and mineral association. It is also shown how this variability can be related to well defined geologic processes.
The influence of sensor noise and diffuse atmospheric radiance in classification accuracy is also analyzed.
