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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Exploring Urban Land Cover Changes and the Effect on Nocturnal Air Temperature Dynamics in Helsingborg - A temperature modeling made with TAPM

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Amanda Bäck; [2023-10-09]
    Keywords : Nocturnal Air Temperature; Intra-Urban Heat Island; Land Cover Classification; Deep learning; The Air Pollution Model TAPM ; Land Cover Change;

    Abstract : In light of increasing global temperatures, urban areas face growing challenges related to heat stress. Alterations in land cover (LC) within cities contribute to changes in the intra-urban climate, predominantly driven by the replacement of vegetated surfaces with impermeable materials. READ MORE

  4. 3. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Ivan Ruzic; [2023-06-21]
    Keywords : heat wave; urban trees; NDVI; remote sensing;

    Abstract : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. READ MORE

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

    University essay from KTH/Geoinformatik

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

    Abstract : 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. READ MORE

  6. 5. Land Use/Land Cover Classification From Satellite Remote Sensing Images Over Urban Areas in Sweden : An Investigative Multiclass, Multimodal and Spectral Transformation, Deep Learning Semantic Image Segmentation Study

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Oskar Aidantausta; Patrick Asman; [2023]
    Keywords : data fusion; deep learning; land use land cover classification; multiclass; multimodal; remote sensing; semantic segmentation; Sentinel satellite; spectral index; U-Net; Urban Atlas;

    Abstract : Remote Sensing (RS) technology provides valuable information about Earth by enabling an overview of the planet from above, making it a much-needed resource for many applications. Given the abundance of RS data and continued urbanisation, there is a need for efficient approaches to leverage RS data and its unique characteristics for the assessment and management of urban areas.
