Detection of initial damage in Norway spruce canopies using hyperspectral airborne data

Abstract

Canopy hyperspectral data (673-724 nm region exhibited maximum sensitivity) were able to separate healthy from initially damaged canopies, and therefore provided an improved capability for assessment of forest physiology as compared to broadband systems.
