Hyperspectral Technology in Vegetation Analysis

Abstract: The objective of the work reported is the development of red-edge methodology in order to characterize agricultural vegetation types and the determination of relationships between different vegetation (high biomass, low biomass) and thermal images. Therefore, the aim was to calculate red-edge position (REP) values and compare them to traditional vegetation indices (NDVI) and thermal images. Images were taken by a DAIS 7915 airborne imaging spectrometer that was equipped with an additional thermal imaging syste… Show more

“…An advantage of Sentinel-2 is its inclusion of spectral bands in the red-edge region of the electromagnetic spectrum (Smith et al 2004). The red-edge describes the spike in vegetation reflectivity between visible red and near infrared wavelengths (approximately 700-790 nm), and indices calculated using the red-edge region have been found to be more sensitive to changes in chlorophyll content (Sims & Gamon 2002;Jung et al 2006;Peng & Gitelson 2011;Schuster et al 2012;Clevers & Gitelson 2013;Hawryło et al 2018;Morley et al 2020). Consequently, Sentinel-2 provides additional potential to resolve subtle changes in chlorophyll content which may lead to an improved early assessment of premature leaf discolouration and senescence in European beech forests.…”

“…For the problem of binary segmentation of soil and vegetation, two vegetation indices were considered: NDVI (normalized difference vegetation index) [13] and EVI (enhanced vegetation index) [14]. These indexes are used to find photosynthetically active biomass:…”
