  1. 1. 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

  3. 2. Interferometric Synthetic Aperture Radar For Track Condition Monitoring. Case Study on Malmbanan

    University essay from Lunds universitet/Trafik och väg

    Author : Kara Åmerbilly; [2021]
    Keywords : InSAR; railway; maintenance; underhåll; järnväg; Technology and Engineering;

    Abstract : There is over 15,000 km of track in the Swedish railroad network. This network is vital for the transport of people and goods across the country. It is important that this network is monitored and maintained to ensure good function and safety. READ MORE

  4. 3. Above-ground biomass estimation in boreal productive forests using Sentinel-1 data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : David Roc Roc; [2019]
    Keywords : synthetic aperture radar SAR ; backscatter intensity; InSAR; interferometric coherence; LIDAR; above-ground biomass; forestry;

    Abstract : Estimation of biomass has high importance for economic, ecologic and climatic reasons due to the multiple ecosystem services offered by forested landscapes. Measurements that are taken in the field incur personal and economic costs. Nevertheless, biomass surveying based on remote sensing techniques offer efficiency thanks to covering large areas.

  5. 4. Modeling of Effective Leaf Area Index

    University essay from SLU/Dept. of Forest Resource Management

    Author : Lina Selin; [2018]
    Keywords : Sentinel-1; tree species; random forest; linear discriminant;

    Abstract : Mapping of e�ective leaf area index (LAIe) over the Swedish boreal forest test site Krycklan (64°N19°E) was performed using ground-based �eld estimates of LAIe and remote sensing data sources. The LAIe data were collected 2017 and 2018 using the LAI-2200 Plant Canopy Analyzer and its later version LAI-2200C Plant Canopy Analyzer. READ MORE

  6. 5. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Cecilia Borghero; [2018]
    Keywords : SAR interferometry; Sentinel-1A; dam deformation monitoring;

    Abstract : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. READ MORE
