  1. 1. Inventering av skred genom jämförelse av två generationer LiDAR-genererad höjddata

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Klara Alm; [2023]
    Nyckelord :Landslides; LiDAR; multi-temporal; DoD; visual observation;

    Sammanfattning : Landslides are a natural hazard that is expected to increase in the future, due to climate change. In order to keep risk management plans up to date, an efficient inventory method is needed. LÄS MER

  3. 2. Mapping Fire Salamander (Salamandra salamandra) Habitat Suitability in Baden-Württemberg with Multi-Temporal Sentinel-1 and Sentinel-2 Imagery

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

    Författare :Andreas Eriksson; [2022]
    Nyckelord :Geography; GIS; Habitat Suitability; Remote Sensing; Image Classification; Earth and Environmental Sciences;

    Sammanfattning : Remote sensing image classification is used in land cover, forest type and tree species classifications but rarely considered for habitat suitability modelling of animal and plant species. It is instead common that land cover products derived from remote sensing data are used in these modelling problems, even though satellite imagery can provide more detailed information. LÄS MER

  4. 3. Mapping wetlands in Sweden using multi-source satellite data and random forest algorithm

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

    Författare :Salvador Hernandez Malave; [2022]
    Nyckelord :physical geography and ecosystem analysis; multi-temporal; Google Earth Engine; machine learning; classification; country-wide; geomatics; Earth and Environmental Sciences;

    Sammanfattning : Wetlands are valuable ecosystems, and assets for human life, that must be regularly monitored, starting with accurately mapping their location and extent. However, an updated national inventory of wetlands is needed. LÄS MER

  5. 4. Cropland and tree cover mapping using Sentinel-2 data in an agroforestry landscape, Burkina Faso

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Ntandokazi Masimula; [2020-06-29]
    Nyckelord :Sentinel-2; Cropland mask; Tree cover estimation; Burkina Faso; Agroforestry; Random Forest;

    Sammanfattning : Sentinel-2, with high spatial resolution bands and increased number of spectral channels, has provided increased capabilities for vegetation mapping. Cropland masks within heterogeneous areas such as the Sudano-Sahel zone have become useful for monitoring landscapes. LÄS MER

  7. 5. Ashish Vivekar (2020) Evaluation of methodology for estimating crop yield from multispectral UAV images : a case study at Lönnstorp, Sweden

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

    Författare :Ashish Vivekar; [2020]
    Nyckelord :Physical Geography and Ecosystem analysis; Multispectral Sensor; Radiometric Correction; Reflection calibration; Phenology; GEM; Earth and Environmental Sciences;

    Sammanfattning : Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. LÄS MER
