  1. 1. Agriculture monitoring using satellite data

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Graff Erik; [2021]
    Keywords : Sentinel; satellite; agriculture; monitoring; dynamic time warping; remote sensing;

    Abstract : As technology advances, the possibility of using satellite data and observations to aid inagricultural activities comes closer to reality. Swedish farmers can apply for subsidies for their land in which crop management and animal grazing occurs, and every year thousands of manual follow-up checks are conducted by Svenska Jordbruksverket (Swedish Board of Agriculture) to validate the farmers’ claims to financial aid.

  2. 2. Using Sentinel-2 Satellite Images to Estimate Traits of Forage Grasslands

    University essay from SLU/Dept. of Agricultural Research for Northern Sweden

    Author : Niklas Zeiner; [2021]
    Keywords : Remote sensing; Forage grasslands; Sentinel-2; Dry matter yield; Canopy average height; Total leaf chlorophyll content; Partial least squares; Support vector machines;

    Abstract : In this project, regression models based on data from field measurements and spectral information extracted from satellite imagery were used to estimate traits of forage grasslands; dry matter yield, canopy average height and total leaf chlorophyll. Four fields at SLUs Röbäcksdalen field station were sampled on 22 occasions and a total of 198 samples, including measurement of the highest plant, canopy height, leaf chlorophyll content, canopy spectral reflectance and biomass were collected.

  3. 3. Combination analysis of multispectral and radar satellite data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Andreas Holmberg; [2021]
    Keywords : ;

    Abstract : Remote sensing technologies, such as satellite imagery, have proven to be a powerful tool for land cover classification when combined with machine learning algorithms. Depending on which type of sensor is used for the imagery, different properties of land cover classes may be distinguished. READ MORE

  4. 4. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ines Júlio Alfredo; [2021]
    Keywords : Sentinel 2; Vegetation Indices; Ground Sensors; Drought and Mire; Earth and Environmental Sciences;

    Abstract : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. READ MORE

  5. 5. Relating land-use and plant biodiversity in Scanian semi-natural grazing lands

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Timothy Micallef; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Land-use; Biodiversity; Grazing land; Remote sensing; Earth and Environmental Sciences;

    Abstract : Climate change and biodiversity loss are amongst the most pressing environmental issues internationally, with far-reaching impacts that place natural and semi-natural habitats at ever greater risk of degradation. My project explores the effects of land-use on plant biodiversity in semi-natural grazing lands using datasets covering Sweden’s southernmost region, Scania. READ MORE
