1. 1. Estimating above ground biomass in a Salix plantation using high resolution UAV images

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Sammanfattning : In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. LÄS MER

3. 2. Assessing avalanche risk by terrain analysis : an experimental GIS-approach to The Avalanche Terrain Exposure Scale (ATES)

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Simon Nåfält; [2016]
   Nyckelord :Altitude; ATES; avalanche; terrain analysis; GIS; Nuolja; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Sammanfattning : This study addresses the complex nature of snow avalanches and how their location can be predicted, and thus avoided, when navigating through mountainous terrain during winter recreations. The avalanche risk in the ski area of Nuolja, in northern Sweden, was evaluated by an experimental implementation of the Avalanche Terrain Exposure Scale (ATES) which is a model for pre-trip planning and assessment of exposure to avalanches.
