In the middle of May we meet in the Krkonoše Mts. with our colleagues from the national park administration to select forest area affected by bark beetle. We scan this area using Headwall NANO-hyperspec hyperspectral camera and also DJI Phantom 4 Multispectral drone almost every week from that time. The main goal is to detect early stages of bark beetle infestation in norway spruce using hyperpsectral data.
