  1. 1. Forest Reaction to the 2018 Drought : comparing the Hyltemossa and Rumperöd Forests

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

    Författare :Emily Delin; [2019]
    Nyckelord :forest; drought; forest management; ecosystem flux; physical geography and ecosystem science; Earth and Environmental Sciences;

    Sammanfattning : This paper analyzes the reactions of two forests, located in the same region, to drought conditions that occurred in 2018. Both locations experienced similar conditions including higher temperature and less precipitation than the previous four years. LÄS MER

  2. 2. Smarter geovisualization tools : a user approach

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

    Författare :Frida Ulfves; [2019]
    Nyckelord :physical geography and ecosystem analysis; geography; geovisualizations; sense of place; user approach; Earth and Environmental Sciences;

    Sammanfattning : Geovisualization tools are continuously becoming more complex. These tools can present vivid and highly accurate representations of the real world. Simultaneously, spatial data is becoming incredibly detailed and the possibilities of interacting with the geovisualization tools are plentiful. Geovisualization tools are indeed powerful. LÄS MER

  3. 3. Climatic effects of changes in radiative forcing due to clear-cutting in Sweden

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

    Författare :Iris Muzic; [2019]
    Nyckelord :Physical Geography and Ecosystem Science; land-cover change; ICOS; albedo; carbon dioxide; radiative forcing; clear-cutting; Earth and Environmental Sciences;

    Sammanfattning : Land cover conversion affects climate by imposing changes in the surface properties and carbon dioxide fluxes. Forest management programs often disregard that modification in surface albedo influences the exchange of energy and climate sensitivity. LÄS MER

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

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

    Författare :Enzo Zerega; [2018]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Developing Data Extraction and Dynamic Data Visualization (Styling) Modules for Web GIS Risk Assessment System (WGRAS)

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

    Författare :Daniel Assefa; [2018]
    Nyckelord :Geographical Information Systems; GIS; Disaster Risk Management; web GIS; Volunteered Geographic Information VGI ; Map Visualization and styling; Geo-spatial data extraction; OpenStreetMap OSM ; Earth and Environmental Sciences;

    Sammanfattning : Interactive web-GIS tools play an important role in determining disaster risk assessment which ultimately result in reduction of unexpected damages, cost and saves millions of lives. Disaster management practitioners largely benefited information at their disposal about location where possible incidents are eminent, anticipate the impact and project possible outcomes to help mitigate and organize proper response.
