  1. 11. Usability of Sentinel-1 C-band VV and VH SAR data for the detection of flooded oil palm

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

    Författare :Sarah Lee Sienaert; [2023]
    Nyckelord :Geography; GIS; Sentinel-1; SAR; C-band; VV; VH; Oil Palm; Flood; Earth and Environmental Sciences;

    Sammanfattning : Flooding in oil palm plantations in Southeast Asia is a common problem. The oil palm’s habitable range is restricted to lowland equatorial areas, and the high rainfall and degraded landscapes associated with oil palm cultivation leaves oil palm prone to flooding. LÄS MER

  3. 12. Deformationsmätning av kubhörnsreflektorer med fotobaserad skanning och terrester laserskanning

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Mathias Erkkilä; Torkel Pettersson; [2022]
    Nyckelord :close-range photogrammetry; terrestrial laser scanning; deformation measurement; corner reflectors; InSAR; fotobaserad skanning; Terrester laserskanning; deformationsmätning; kubhörnsreflektor; InSAR;

    Sammanfattning : Kubhörnsreflektorer används som måltavlor med kontinuerlig och identifierbar reflekterad signalstyrka vid fjärranalys, bland annat för tekniken ”interferometric synthetic aperture radar” [InSAR]. Kubhörnsreflektorer tillämpas exempelvis för bevakning av sättningar i jordytan och kalibrering av [SAR]-system (”synthetic aperture radar”). LÄS MER

  4. 13. Investigation of Registration Methods for High Resolution SAR-EO Imagery

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Niclas Hansson; [2022]
    Nyckelord :SAR; FFT; MI; Image Registration;

    Sammanfattning : With advancements in space technology, remote sensing applications, and computer vision, significant improvements in the data describing our planet are seen today. Researchers want to gather different kinds of data and perform data fusion techniques between them to increase our understanding of the world. LÄS MER

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

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ida Rehn; [2022]
    Nyckelord :InSAR; Sentinel-1; SBAS; Permafrost; Subsidence; Permafrost thaw;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Sammanfattning : 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.
