Comparative Assessment of Broadband Vegetation Indices Over Aquatic Vegetation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
Remote sensing is one of the most useful tools for mapping and studying vegetation because of the advantages of synoptic view (in time and space) compared to traditional in situ survey. Remotely sensed vegetation indices (VIs) derived from airborne and satellite images represent a powerful and effective way to monitor vegetation status, growth, and bio-

Estimation of Crop Growth Parameters Using UAV-Based Hyperspectral Remote Sensing Data

open access: yesSensors, 2020
Above-ground biomass (AGB) and the leaf area index (LAI) are important indicators for the assessment of crop growth, and are therefore important for agricultural management. Although improvements have been made in the monitoring of crop growth parameters
