  1. 1. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

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

    Författare :Jip Jan van Zoonen; [2020]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Sammanfattning : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. LÄS MER

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

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

    Författare :Shuo Yang; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Commuting to Skåne’s Regional Centers - A Quantitative Study of Opportunities and Possible Consequences for Students

    Kandidat-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Författare :Alva Rosager; [2019]
    Nyckelord :school commute; time geography; public transport; school choice; Skåne; Social Sciences;

    Sammanfattning : Region Skåne has designated seven regional centers in Skåne: Malmö, Lund, Helsingborg, Landskrona, Hässleholm, Kristianstad and Ystad. These centers are to be, among other things, providers of key services. LÄS MER

  4. 4. Multi-Criteria GIS modelling for optimal alignment of roadway by-passes in the Tlokweng Planning Area, Botswana

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

    Författare :Milan Sekulic; [2019]
    Nyckelord :GIS; Multi-criteria analysis; DEFINITE; Sensitivity Analysis; Python; AHP; Least-cost path; Dijkstra’s algorithm; ArcPy; Geography; model; road alignment; Earth and Environmental Sciences;

    Sammanfattning : To find the optimal by-pass road alignment in the Tlokweng Planning Area in Botswana, a multi-criteria spatial-based model is developed using the GIS-MCE approach. In respect to the environmental impact assessment (EIA) approach, in this research a set of criteria is classified under 3 themes – economic, environmental and social. LÄS MER

  5. 5. Land cover changes in Southern Sweden from the mid-Holocene to present day: insights for ecosystem service assessments

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

    Författare :Robert O'Dwyer; [2019]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Götaland; Landscape Reconstruction Algorithm; Fossil Pollen; Ecosystem Services; Earth and Environmental Sciences;

    Sammanfattning : Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from pollen information.
