  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. Detaljmätning med terrester fotogrammetri : Med smartphone, bildrover och multistation

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS; Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Johannes Nyström; Hampus Tholander; [2018]
    Nyckelord :Terrester fotogrammetri; Detaljmätning; Trimble V10 Imaging Rover; Trimble SX10; iPhone 7;

    Sammanfattning : Detaljmätning genomförs främst genom traditionella metoder, d.v.s. mätning med Global Navigation Satellite System (GNSS) eller totalstationsmätning. LÄS MER

  5. 5. Use of Satellite Data for Prediction of Weather Impact on EO-Systems

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Cecilia Gullström; [2018]
    Nyckelord :EO-systems; Aerosols; Extinction coefficient; Satellite data; CALIPSO; EO-system; Aerosoler; Extinktionskoefficient; Satellitdata; CALIPSO;

    Sammanfattning : To predict the performance of an electro-optical sensor system (EO-system) requires taking the weather situation into consideration. The possibility to use weather data from satellites instead of ground – and flight stations has been investigated. LÄS MER
