  1. 11. Development of a deep learning method for soil moisture estimation at high spatial and temporal resolution using satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nicklas Simonsen; [2021]
    Keywords : Physical Geography and Ecosystem Analysis; Machine Learning; Deep Learning; Recurrent Neural Network; LSTM; Soil Moisture; Remote Sensing; SAR; Sentinel-1; Sentinel-2; ISMN; ICOS: Geomatics; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) is an essential climate variable that controls fundamental hydrological and climatic processes. Soil moisture products derived from microwave remote sensing often provide measurements at low spatial resolution and incomplete temporal records. READ MORE

  2. 12. Addressing the urban heat island effect in Stockholm : An analysis of its presence and relation to land cover and urban planning

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fanny Igergård; [2021]
    Keywords : urban heat islands; land surface temperature; land cover; urban planning; GIS; urbana värmeöar; yttemperatur; marktäcke; stadsplanering; GIS;

    Abstract : As urbanization and global warming increase, an increasing importance is set on that urban planning processes take the possible effects of urban heat islands into account. In order to provide local city planners with site specific knowledge of the current situation in Stockholm, this study has explored the intra-urban heat island effect in Stockholm municipality by identifying major problem areas as well as addressing the statistical relationship between temperature and factors relating to land cover and urban planning strategies.

  3. 13. Soil organic carbon prediction using Sentinel-2 data and the LUCAS topsoil database

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Philipp Hansen; [2020]
    Keywords : Sentinel-2 LUCAS topsoil database Soil organic carbon mapping Multispectral data; Earth and Environmental Sciences;

    Abstract : Its carbon sink potential as well as soil fertility benefits make organic carbon a soil variable for which reliable quantification methods are sought. This thesis work aims at investigating the possibility of adapting a large soil spectral library to build models for SOC predictions with remotely sensed, multispectral data. READ MORE

  4. 14. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jip Jan van Zoonen; [2020]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Abstract : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. READ MORE

  5. 15. Wildfire Hazard Mapping using GIS-MCDA and Frequency Ratio Models : A Case Study in Eight Counties of Norway

    University essay from Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnad

    Author : Walelegn Mengist Zeleke; [2019]
    Keywords : Wildfire; GIS; MCDA; Frequency Ratio; Hazard Map; Constraint Criteria; Factor Criteria; AUC;

    Abstract : Abstract A wildfire is an uncontrollable fire in an area of combustible fuel that occurs in the wild or countryside area. Wildfires are becoming a deadly and frequent event in Europe due to extreme weather conditions. In 2018, wildfires profoundly affected Sweden, Finland, and Norway, which were not big news before.
