  1. 21. Assessing the suitability of using Sentinel-1A SAR multi-temporal imagery to detect fallow periods between rice crops

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lukasz Langowski; [2021]
    Keywords : Geography; Geographical Information System; GIS; Remote Sensing; Fallow; Detection; Sentinel-1A; Synthetic-aperture radar; SAR; Earth and Environmental Sciences;

    Abstract : Fallow, understood as a period where no crop is cultivated during a growing season, is an important crop management practice. Fallow plays an important role in pest and disease management, and monitoring the presence and duration of fallow can have implications for understanding the extent and effectiveness of this agricultural practice.

  3. 22. Change of heating fuel consumption patterns produced by the economic crisis in Greece

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Panagiotis Patrinos; [2021]
    Keywords : geography; GIS; atmospheric pollution; Greece; household heating systems; heating fuel; economic Crisis; air Quality; satellite data; virtual stations; regression analysis; air pollutants mapping; anthropogenic factors; Earth and Environmental Sciences;

    Abstract : The economic crisis in Greece resulted in a change in residential heating fuels utilized, which in turn resulted in a change of air quality over Greater Athens Area. The aim of this study was to investigate the effects of economic crisis in air quality over Attica by examining the change in air pollutants’ concentrations before, during, and after the onset of the economic crisis in Greece and to associate this change with the change in fuels used for residential heating.

  4. 23. Deep Learning for Earth Observation: improvement of classification methods for land cover mapping : Semantic segmentation of satellite image time series

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Benjamin Carpentier; [2021]
    Keywords : Satellite Image Time Series; Remote sensing; Land Cover Classification; Deep Learning; Convolutional Neural Network; Tidsserier av satellitbilder; Fjärranalys; Classificering; Djupinlärning; KonvolutionelltNeuralt Nätverk;

    Abstract : Satellite Image Time Series (SITS) are becoming available at high spatial, spectral and temporal resolutions across the globe by the latest remote sensing sensors. These series of images can be highly valuable when exploited by classification systems to produce frequently updated and accurate land cover maps. READ MORE

  5. 24. Mapping time-series evapotranspiration for agricultural applications

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Erik Jan Bootsma; [2021]
    Keywords : ;

    Abstract : Fresh water provides a range of essential services and is often used for irrigation purposes. Decreasing precipitation and increasing temperatures caused by climate change together with increased usage by humans has put these resources under stress, especially in relatively dry areas.

  6. 25. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lotte Wendt; [2021]
    Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

    Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.
