Towards a Standard Plant Species Spectral Library Protocol for Vegetation Mapping: A Case Study in the Shrubland of Doñana National Park

Researchers developed a standard protocol for creating spectral libraries of plant species to improve vegetation mapping accuracy using imaging spectroscopy. The study, conducted in Doñana National Park's shrubland, focused on five dominant shrub species: Erica scoparia, Halimium halimifolium, Ulex australis, Rosmarinus officinalis, and Stauracanthus genistoides. Findings indicated significant intra-species variability (p < 0.05) using the Student's t-test, while spectral similarity value (SSV) and spectral angle mapper (SAM) algorithms demonstrated notable separability among species, though Ulex australis and Stauracanthus genistoides could not be distinguished. This protocol aims to enhance the reliability of spectral libraries by standardizing data acquisition methods, accounting for spatiotemporal variations in plant reflectance.
