Seasonal trends in separability of leaf reflectance spectra for Ailanthus altissima and four other tree species
… regions of atmospheric absorption were removed. Continuum removal was performed on the reflectance data, resulting in a second dataset. For both the reflectance and continuum removed datasets, least angle regression (LARS) and random forest classification were used to identify a single set of …

Spectral Reflectance as an Indicator of Water Quality in Streams Impacted by Mine Drainage
… the sediments correlated with stream water pH. Continuum removal analysis of mineral VNIRreflectance spectra indicated that the presence of sulfate associated with the sediments shifted primary absorption bands to lower wavelengths. Spectral analysis results were used to classify Digital …

Hydrocarbon pollutant impact on spectral and biophysical properties of willow and grass species
… changes in spectral response were analysed using continuum removal analysis and vegetation indices. Absorption features were identified related to pigment concentration (chlorophyll, carotenoids and anthocyanin) and biomass (starch, cellulose, lignin and water). Variations in absorption feature …

Examining UAV-based LiDAR, Multispectral, Hyperspectral and Precision Photogrammetry Approaches for Tidal Salt Marsh Environments
Tidal salt marshes are one of the most productive and valuable ecosystems on Earth, providing multiple ecosystem services such as blue carbon trapping and coastal flood mitigation. However, this ecosystem is under serious threat due to human activities and rising sea levels. The purpose of this …
