  1. 1. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shuo Yang; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Abstract : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. READ MORE

  2. 2. Conflict, narratives, and forest fires in eastern Turkey : a quantitative perspective with remote sensing and GIS

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aiman Shahpurwala; [2019]
    Keywords : geography; burned area; Turkey; warfare ecology; spatial analysis; GEM; Earth and Environmental Sciences;

    Abstract : Within Turkey, claims of an increasing number of forest fires ignited by the Turkish military to ‘strategically degrade the environment’ broke out after the Turkish-Kurdish peace process ended in 2015. These claims are built on little evidence, and fire occurrences are not well documented. READ MORE

  3. 3. Assessing edge pixel classification and growing stock volume estimation in forest stands using a machine learning algorithm and Sentinel-2 data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Enzo Zerega; [2018]
    Keywords : Physical Geography; Ecosystem Analysis; Random Forest; remote sensing; accuracy assessment; land cover classification; training stage; multi-temporal; edge areas; Earth and Environmental Sciences; Science General;

    Abstract : Sustainable forest management requires accurate and up-to-date baseline data regarding forest structural parameters and the definition of forest stand units. A crucial component in stand characterization is the identification of tree species and to correctly define the stand boundaries. READ MORE

  4. 4. Tree species classification using multi-temporal Sentinel-2 data

    University essay from SLU/Dept. of Forest Resource Management

    Author : Magnus Persson; [2018]
    Keywords : sentinel-2; tree species; random forest; recursive feature elimination;

    Abstract : The Sentinel-2 program provides the opportunity to monitor terrestrial ecosystems with a high temporal- and spectral resolution. In this study, the utilization of multi-temporal Sentinel-2 imagery and it’s spectral variation due to phenology for classification of common tree species is evaluated at the forest estate Remningstorp in central Sweden.

  5. 5. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Cecilia Borghero; [2018]
    Keywords : SAR interferometry; Sentinel-1A; dam deformation monitoring;

    Abstract : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. READ MORE
