  1. 1. Deep Learning for Building Damage Assessment of the 2023 Turkey Earthquakes : A comparison of two remote sensing methods

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :Tobias Karlbrg; Jennifer Malmgren; [2023]
    Nyckelord :Deep learning; U-Net; Earthquake-induced building damage; VHR satellite imagery; Djup maskininlärning; U-Net; Byggnadsskador; Jordbävning; Satellitbilder;

    Sammanfattning : Current disaster response strategies are based on damage assessments carried out on the ground, which can be dangerous following a ä destructive event. Damage assessments can also be performed remotely using satellite imagery, but are usually carried out through visual interpretation, which can take a lot of time. LÄS MER

  3. 2. Using remote sensing and aerial archaeology to detect pit house features in Worldview-2 satellite imagery. : A case study for the Bridge River archaeological pit house village in south-central British Columbia, Canada.

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Sarah Cooke; [2017]
    Nyckelord :Remote Sensing; Aerial Archaeology; Pit House Archaeology; Geographic Information Systems GIS ; Satellite Imagery;

    Sammanfattning : It is well known that archaeological sites are important sources for understanding past human activity. However, those sites yet to be identified and further investigated are under a great risk of being lost or damaged before their archaeological significance is fully recognized. LÄS MER

  4. 3. Spatial assessment of NDVI as an indicator of desertification in Ethiopia using remote sensing and GIS

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

    Författare :Gezahagn Negash Seboka; [2016]
    Nyckelord :NDVI and Rainfall; land degradation; climate change; desertification; NOAA AVHRR; land cover; GIS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Sammanfattning : Desertification is a serious environmental and socio-economic problem occurring at global, regional and local scale. According to Article 1(a) of the United Nations Convention to Combat Desertification (UNCCD), define the term “desertification” means “land degradation in arid, semi-arid and dry sub-humid (dry lands) areas resulting from various factors, including climatic variations and human activities”.

  5. 4. Geometric quality assessment of multi-rotor unmanned aerial vehicle borne remote sensing products for precision agriculture

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

    Författare :Jayan Wijesingha; [2016]
    Nyckelord :OrthoMosaic; blurriness; geometric accuracy; UAV; precision agriculture PA ; Digital Surface Model DSM ; geomatics; Physical Geography and Ecosystems Analysis; Earth and Environmental Sciences;

    Sammanfattning : Sub-meter level spatial resolution remote sensing products are essential for Precision Agriculture (PA) applications. Recent development of Unmanned Aerial Vehicle (UAV) with imaging sensors provides opportunity to generate sub-meter level, timely, and cloud free remote sensing products. LÄS MER

  7. 5. Exploring the relationships between biodiversity and benthic habitat in the Primeiras and Segundas Protected Area, Mozambique

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

    Författare :Luisa Teixeira; [2015]
    Nyckelord :fish biodiversity; coral reef; benthic habitats; object-based image classification; very-high resolution remote sensing; geography; physical geography; Earth and Environmental Sciences;

    Sammanfattning : A Reserva dos Arquip�lagos Primeiras e Segundas, localizada no norte de Mo�ambique, � a maior zona mar�tima protegida de �frica, estendendo-se por mais de 200 km de costa. Apesar da sua import�ncia para a economia local, informa��es sobre os seus ecossistemas marinhos, e particularmente habitats b�nticos, s�o escassas. LÄS MER
