  1. 1. Land cover classification using machine-learning techniques applied to fused multi-modal satellite imagery and time series data

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

    Författare :Anastasia Sarelli; [2024]
    Nyckelord :Geography; GIS; Land Cover Classification; Landsat; Machine Learning; Earth and Environmental Sciences;

    Sammanfattning : Land cover classification is one of the most studied topics in the field of remote sensing, involving the use of data from satellite sensors to analyze and categorize different land surface types. There are numerous satellite products available, each offering different spatial, spectral, and temporal resolutions. LÄS MER

  3. 2. GIS and remote sensing based mapping of microtopography and vegetation composition in a boreal mire complex

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Nils Helge Havertz; [2023]
    Nyckelord :Microtopography modelling; Remote sensing; Boreal mixed mires; Object Based Image Analysis OBIA ; random forest RF ;

    Sammanfattning : Small scale variations in mire surface elevation referred to as microtopography are fundamental characteristics of mire ecosystems especially in the boreal region. Microtopography commonly classified into hummocks and hollows play a major role in several ecological, hydrological and biogeochemical processes including vegetation composition and carbon and methane dynamics.

  4. 3. Vulnerable Populations and Urban Heat Islands: A Spatial Analysis of Socio-Demographic Factors and Heat Exposure in Stockholm

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :William Godée; Hugo Lemna; [2023]
    Nyckelord :UHI; Urban Heat Islands; Stockholm; Spatial Analysis; GIS; ArcGIS; Regression; Vulnerable Population; Urbana Värmeöar; Stockholm; Rumslig Analys; GIS; ArcGIS; Regression; Sårbar Population;

    Sammanfattning : The important urban issue of urban heat islands in Stockholm is examined in this thesis. These places influence urban sustainability, liveability, and public health because of the much higher temperatures they experience relative to their surroundings. LÄS MER

  5. 4. DEVELOPING METHODS FOR WATER QUALITY MEASUREMENT : Using machine learning and remote sensing to predict absorbance with multispectral imaging

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Ola Bratt; [2023]
    Nyckelord :Remote Sensing; Multivariate Analysis; Machine Learning; GIS; Spectroscopy; Spectral imaging; Multispectral imaging; Water Quality;

    Sammanfattning : Water resources play an important role in society and fulfill various functions such as providing drinking water, supporting industrial production and enhancing the overall landscape. Water bodies, such as rivers and lakes, are particularly important in this context. LÄS MER

  7. 5. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea

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

    Författare :Krystyna Muszel; [2023]
    Nyckelord :Geography; GIS; North Sea; phytoplankton; bloom; phenology; remote sensing; TIMESAT software; Earth and Environmental Sciences;

    Sammanfattning : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. LÄS MER
