The limited forest canopy penetration of ... -
Predicting living and dead wood volumes in a mature managed Swedish forest with airborne laser scanning
Swärd, Hans Yngve Ivar (Master thesis, 2022)Detecting dead wood with airborne laser scanning (ALS) would have many benefits. It would make it easier to find areas with high mortality rates, help make better decisions on which areas to preserve, and increase the ... -
Predicting the Extent of Root and Butt rot in Stems of Norway Spruce (Picea abies)
Tollefsen Moen, Ole Marius (Master thesis, 2020)Commercially, Norway spruce (Picea abies (L.) Karst) is the most important tree species in Norway, representing 72% of the industrial timber volume sold in 2019. However, Norway spruce is particularly prone to infection ... -
Predikering av råte i granskog med hyperspektrale flybilder og maskinlæring
Hagen, Kristoffer Hönl (Master thesis, 2020)Råte i granskog (picea abies) fører i Norge til store økonomiske tap for skogbruket. Årlig går verdier på rundt 100 millioner tapt. Det er tidligere gjort studier på bruk av maskinlæring for predikering av råte i granskog, ... -
