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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  4. 4. Dehazing of Satellite Images

    University essay from Linköpings universitet/Datorseende

    Author : Johanna Hultberg; [2018]
    Keywords : Dehazing; Satellite Images; Dark Channel; Remote sensing;

    Abstract : The aim of this work is to find a method for removing haze from satellite imagery. This is done by taking two algorithms developed for images taken from the sur- face of the earth and adapting them for satellite images. The two algorithms are Single Image Haze Removal Using Dark Channel Prior by He et al. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Enzo Zerega; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE
