Bestemmelse av diameterfordeling i bestand : sammenligninger av ulike takstopplegg
Eid, Tron; Gobakken, Terje; Næsset, Erik (MINA fagrapport;6, Report, 2005)Verdiskapningen og konkurransekraften i skogbruk og skogindustri vil kunne øke dersom skogbruksplanene inneholder nyttig informasjon for videreforedling av tømmeret. Hensikten med dette arbeidet har vært å sammenligne ulike ... -
Biomass estimation models and methods for miombo woodlands of Malawi using field and remotely sensed data
Kachamba, Daud Jones (PhD Thesis;2016:92, Doctoral thesis, 2016)Dry tropical forests, such as the miombo woodlands, play an important role in the global carbon budget as well as in contributing towards the sustainable development of countries such as Malawi. To ensure sustainability ... -
Biomass Estimation Using 3D Data from Unmanned Aerial Vehicle Imagery in a Tropical Woodland

Bruk av flybåren hyperspektral sensor for påvisning av råte i stående granskog (Picea abies)
Sørhuus, Øyvind (Master thesis, 2019)Det økonomisk viktigste treslaget i Norge er gran (Picea abies (L.) Karst.). Kvaliteten på tømmeret er en avgjørende faktor for det økonomiske utbytte en skogeier vil få fra skogen. Råte er en skadegjører som påvirker den ... -
Bruk av hogstmaskindata som referansedata ved ressurskartlegging av salgbart volum og sagtømmervolum
Råheim, Mikal (Master thesis, 2021)Oversikt over skogens ressurser og tilstand er en viktig forutsetning for å drive rasjonelt skogbruk. En skogbruksplan er en viktig kilde til slik informasjon, og gir grunnlag for fremtidig skogbruksplanlegging. Siden ... -
