Coupling a differential global navigation satellite system to a cut-to-length harvester operating system enables precise positioning of harvested trees
Noordermeer, Lennart; Sørngård, Erik; Astrup, Rasmus; Næsset, Erik; Gobakken, Terje (Peer reviewed; Journal article, 2021-03-30)Cut-to-length harvesters collect detailed information on the dimensions and characteristics of individual harvested trees. When equipped with global navigation satellite system (GNSS) receivers and motion sensors, the ... -
Detection of Root, Butt, and Stem Rot presence in Norway spruce with hyperspectral imagery
Allen, Benjamin James; Dalponte, Michele; Hietala, Ari Mikko; Ørka, Hans Ole; Næsset, Erik; Gobakken, Terje (Peer reviewed; Journal article, 2022-02-16)Pathogenic wood decay fungi such as species of Heterobasidion are some of the most serious forest pathogens in Europe, causing rot of tree boles and loss of growth, with estimated economic losses of eight hundred million ... -
Estimating stand level stem diameter distribution utilizing harvester data and airborne laser scanning
Maltamo, Matti; Hauglin, Marius; Næsset, Erik; Gobakken, Terje (Journal article; Peer reviewed, 2019-08-07)Accurately positioned single-tree data obtained from a cut-to-length harvester were used as training harvester plot data for k-nearest neighbor (k-nn) stem diameter distribution modelling applying airborne laser scanning ... -
Fjernmåling av barmasse - en skoghelsevariabel
Solberg, Svein; Lange, Holger; Næsset, Erik; Aurdal, Lars; Solberg, Rune (Glimt fra skogforskningen;1-2005, Others, 2005)Barmasse er sterkt knyttet til kronetetthet og til bladarealindeks (LAI), og er viktig for fjernmåling av skogens helsetilstand. Vi kan nå presentere foreløpige, men lovende resultater for måling av barmasse ved hjelp av ... -
Harvested area did not increase abruptly—how advancements in satellite-based mapping led to erroneous conclusions
Breidenbach, Johannes; Ellison, David; Petersson, Hans; Korhonen, Kari T.; Henttonen, Helena M.; Wallerman, Jörgen; Fridman, Jonas; Gobakken, Terje; Astrup, Rasmus Andreas; Næsset, Erik (Peer reviewed; Journal article, 2022-02-22)Key message: Using satellite-based maps, Ceccherini et al. (Nature 583:72-77, 2020) report abruptly increasing harvested area estimates in several EU countries beginning in 2015. Using more than 120,000 National Forest ... -
