First spectral Reflectance Dataset of Equisetum hyemale (Snake grass) Invasive Alien Plant

This repository contains the first spectral reflectance dataset of snakegrass (Equisetum hyemale) invasive alien species recorded in South Africa. Spectral reflectance measurements were collected under lab conditions using the Spectral Evolution PSR-300 full-range spectrometer. Spectral pre-processing was performed in R statistical software to remove noisy spectra and regions and perform averaging per sample (code accessible: https://github.com/mkganyago/SpectralEvolutionFileReader).
