Monitoring inland water is crucial for assessing different aspects of the hydrological cycle, as well as environmental and atmospheric processes within the Earth system. Understanding hydrological processes and managing water resources and ecosystem balance depend greatly on tracking changes in water levels. Traditionally, water levels have been observed using in-situ gauging stations; however, the global network of these stations is Continue Reading »

Chlorophyll is the most dominant plant pigment, essential for photosynthesis, and largely determines the spectral reflectance of healthy vegetation. Its higher concentration often overshadows the detection of other pigments like carotenoids. Carotenoids (C40H56O2), being an accessory light absorbing pigment, is the second most abundant plant pigment. They comprise several constituents, including β-carotene, xanthophylls, lutein, violaxanthin, and neoxanthin, which play a Continue Reading »

Remote sensing refers to the technique of capturing information at a distance (remotely) by specific instruments (sensors). Traditionally, remote sensing has been associated with satellites or manned aircraft with a set of airborne sensors. In the last decade, the increasing developments and improvements in unmanned platforms, together with the development of sensing technologies installed on drones, provide excellent opportunities for Continue Reading »
