This paper establishes the rigorous mathematical foundation for orbital continuum removal and non-negative least squares library unmixing against a public laboratory spectral library. Blind cross-validation against ground-truth field spectroscopy is reported in the paper, without reliance on black-box heuristics.
Applied orbital spectroscopy for geothermal alteration cap mapping, microseepage identification, and pipeline corridor terrain stability. We demonstrate how narrow SWIR ammonium illite signatures and thermal inertia anomalies pinpoint blind hydrothermal reservoirs without destructive surface disruption.
Quantitative bio-optical inversion for inland water monitoring, resolving phycocyanin absorption features (620 nm), chlorophyll-a absorption (665 nm), and total suspended matter scattering across complex Case-2 inland water bodies.
Sub-pixel spectral unmixing and radiative transfer modeling of forest canopy biophysical variables, quantifying Equivalent Water Thickness (EWT), chlorophyll red-edge inflection shifts, and selective timber harvesting disturbance.
Orbital shortwave infrared characterisation of agricultural soils, extracting the Cellulose Absorption Index (CAI) for crop residue cover, clay mineral composition, and soil organic carbon (SOC) baseline proxies across bare soil windows.
How plot level satellite evidence supports due diligence under the European Union Deforestation Regulation: what a plot was at the 31 December 2020 cut-off, what has changed inside it since, and what replaced the canopy where it did. Written for compliance platforms, traders and processors filing due diligence statements, the producers asked to prove their plantations, and the auditors who read the evidence.
