Hyperspectral remote sensing of the stages of beech bark disease infection on American Beech (Fagus grandifolia) in southern Québec
This study aims to find hyperspectral differences between the beech bark disease infection stages using remote sensing technology. The main goal is to identify the infection stage of American beech (Fagus grandifolia) individuals and of whole populations by looking at aerial images. Foliar spectroscopy will also be used to study the chemical changes happening in the beech leaves throughout the different phases of infection. This biodiversity survey is included in the CABO (Canadian Airborne Biodiversity Observatory) project.
