  1. 1. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

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

    Författare :Alicja Miodonska; [2019]
    Nyckelord :remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Sammanfattning : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. LÄS MER

  2. 2. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

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

    Författare :Aleksandra Ivanova; [2019]
    Nyckelord :physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Sammanfattning : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. LÄS MER

  3. 3. Global satellite data as proxies for urbanization in flood prone areas

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Florian van Schaik; [2018]
    Nyckelord :flood exposure; global satellite data; urbanization; remote sensing; sustainable development;

    Sammanfattning : Delta regions are typically characterized by their high population density, low elevation, and risk of flooding. Long term planning and preparation is needed to mitigate the adverse effects of floods. LÄS MER

  4. 4. Deep Fusion of Imaging Modalities for Semantic Segmentation of Satellite Imagery

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Carl Sundelius; [2018]
    Nyckelord :Semantic segmentation; convolutional neural networks; remote sensing; satellite imagery; multimodal images;

    Sammanfattning : In this report I summarize my master’s thesis work, in which I have investigated different approaches for fusing imaging modalities for semantic segmentation with deep convolutional networks. State-of-the-art methods for semantic segmentation of RGB-images use pre-trained models, which are fine-tuned to learn task-specific deep features. LÄS MER

  5. 5. Delineation of Ditches in Wetlandsby Remote Sensing

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten och landskapslära; Uppsala universitet/Luft-, vatten och landskapslära

    Författare :Andreas Gustavsson; Selberg Martin; [2018]
    Nyckelord :GIS; drainage network; LiDAR; GIS; dräneringsnätverk; LiDAR;

    Sammanfattning : Wetlands have been heavily affected by human-alteration, this is done to drain thewetland so that the ground can be used for other purposes such as forestry oragriculture. With high accuracy data available now, it is possible to use differentmethods automatically to identify these ditches in wetlands or other areas. LÄS MER
