Moisture content in soils, regolith, and rocks influences hyperspectral measurements and subsequent mineral classification. It is important to understand the systematic effects of changing moisture content on spectra and on the classification accurac

A continuously changing solar position affects outdoor hyperspectral measurements and classifications results. It is important to know how much spectra vary with a changing zenith angle and which classification technique is least affected. In this re

Capable of retaining rainwater, Organic Ground Cover (OGC) is an ecological material for urban greening. The water absorption features of various OGC materials should be identified before selecting the proper OGC for places under different climates.

The contamination of farmlands with hazardous metals from mining puts the safety of agricultural commodities at risk. For remediation, it is crucial to map the spatial distribution of contaminated soil. Typical sampling-based procedures are time-cons

In this paper, we propose to extract spectral absorptions as the discriminative features to classify hyperspectral imagery. Different from previous researches that mainly take hyperspectral curves as high-dimensional inputs, we analyze hyperspectral

Reflectance spectroscopy has been used to identify several deposit types. However, applications concerning lithium (Li)-pegmatites are still scarce. Reflectance spectroscopic studies complemented by microscopic and geochemical studies were employed i
