  1. 6. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : André Farjami; [2022-09-09]
    Keywords : ;

    Abstract : During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by the end of this century. Since subarctic peatlands account for 30% of the global soil organic carbon storage, small degradation changes in these areas globally, can potentially change the greenhouse gas emissions on a worldwide scale.

  2. 7. Damage Assessment of the 2022 Tongatapu Tsunami : With Remote Sensing

    University essay from KTH/Geoinformatik

    Author : Milton Larsson; [2022]
    Keywords : remote sensing; land cover classification; Sentinel-1; Sentinel-2; change detection; change vector analysis;

    Abstract : The Island of Tongatapu, Tonga, was struck by a tsunami on January 15, 2022. Internet was cut off from the island, which made remote sensing a valuable tool for the assessment of damages. Through land cover classification, change vector analysis and log-ratio image differencing, damages caused by the tsunami were assessed remotely in this thesis. READ MORE

  3. 8. Seasonal permafrost subsidence monitoring in Tavvavuoma (Sweden) and Chersky (Russia) using Sentinel-1 data and the SBAS stacking technique

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ida Rehn; [2022]
    Keywords : InSAR; Sentinel-1; SBAS; Permafrost; Subsidence; Permafrost thaw;

    Abstract : Permafrost deformation is expected to increase due to climatic perturbations such as amplified air and soil temperatures, resulting in permafrost thawing and subsequent subsidence. Palsas and peat plateaus are uplifted ice-rich peat mounds that experience permafrost subsidence. READ MORE

  4. 9. Evaluation of a change detection approach to map global flood extents using Sentinel-1

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Axel Risling; [2022]
    Keywords : Flood mapping; global flood models; synthetic aperture radar; cloud-computing; change detection; Översvämningskartering; globala översvämningsmodeller; syntetisk aperturradar; molntjänster; förändringsdetektering;

    Abstract : Floods are the most frequent disaster in the world and flood exposure is increasing globally. Flood mapping of past events can be a useful aid in not only disaster risk management, but also in evaluating and validating global flood models (GFMs) which are being used to assess and predict these floods.

  5. 10. A study on the urbanization of Bengaluru, India between 2015 and 2020 based on Sentinel-1/2 data

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

    Author : Shreyas Goswami; [2021]
    Keywords : ;

    Abstract : Availability of timely information about land-use and land-cover (LULC) changes is essential for understanding and modelling the urbanization pattern, and thereby in planning sustainable urban development of a region accordingly. Remote sensing technology, using Earth observation satellites, has emerged as a reliable tool for timely monitoring of changes anywhere on Earth. READ MORE
