    Sammanfattning : Today, people are used to having technology as a constant aid. This also sets expectations that information should always be available. LÄS MER

  2. 2. Damage Assessment of the 2018 Swedish Forest Fires Using Sentinel-2 and Pleiades Data

    Kandidat-uppsats, KTH/Geoinformatik; KTH/Geoinformatik

    Författare :Patrik Grenert; Linus Bäckström; [2019]
    Nyckelord :Damage Assessment; Sentinel-2; Pleiades; Forest Fire dNBR classification; Supervised image classificaiton; Sweden; 2018; Trängslet; Lillhärdal 2018;

    Sammanfattning : When a devastating event such as a forest fire occurs, multiple actions have to be taken. The first priority is to ensure people's safety during the fire, then the fire has to be kept under control and finally extinguished. After all of this, what remains is a damaged area in the forest.

  3. 3. Feature Extraction and FeatureSelection for Object-based LandCover Classification : Optimisation of Support Vector Machines in aCloud Computing Environment

    Master-uppsats, KTH/Geoinformatik

    Författare :Oliver Stromann; [2018]
    Nyckelord :Feature Extraction; Feature Selection; Dimensionality Reduction; Supervised Object-Based Land Cover Classification; Google Earth Engine;

    Sammanfattning : Mapping the Earth’s surface and its rapid changes with remotely sensed data is a crucial tool to un-derstand the impact of an increasingly urban world population on the environment. However, the impressive amount of freely available Copernicus data is only marginally exploited in common clas-sifications. LÄS MER

  4. 4. Analysis of Arctic peak-season carbon flux estimations based on four MODIS vegetation products

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

    Författare :Antonin Kusbach; [2016]
    Nyckelord :satellite-derived data; vegetation indices; Arctic; net ecosystem exchange; big data analysis; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Sammanfattning : Increased temperatures in high latitudes may alter the carbon dynamics throughout the Arctic. Modelled CO2 simulations show that current climate conditions constitute the Arctic a net carbon sink, though the large extent and fine landscape heterogeneity raise an uncertainty about the carbon sink/source status of the region.
