  1. 1. Flood Simulation in the Colombian Andean Region Using UAV-based LiDAR : Minor Field Study in Colombia

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Simon Höglund; Linus Rodin; [2023]
    Keywords : UAV; Unmanned aerial vehicle; LiDAR; Light detection and ranging; UAV-based LiDAR; UAV photogrammetry; Aerial photogrammetry; Flooding Colombia; UN Sustainability Development Goals; UAV; Obemannade flygfordon; LiDAR; Ljus- och avståndsdetektion; UAV-baserad LiDAR; UAV-fotogrammetri; Flygfotogrammetri; Översvämning Colombia; FN; hållbarhetsutvecklingsmål;

    Abstract : Flooding is a worldwide problem that every year causes substantial damage for the environment and stakeholders nearby, and this impact relates to several of the United Nations Sustainable Development Goals. Colombia is specially prone to flooding as 17% of its surface area is at risk of extreme flooding. READ MORE

  3. 2. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kyle William Coble; [2023]
    Keywords : Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Abstract : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. READ MORE

  4. 3. Geo-Enabling Piste Maps Using Anchor Points

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lou-Lou Pei; [2021]
    Keywords : Georeferencing; Positioning; Coordinate Transformations; Piste maps; Geografiska referenspunkter; Positionering; Koordinattransformationer; Pistkartor;

    Abstract : Piste maps have been used as navigational aids by winter sports enthusiasts for decades. These maps are often hand drawn and are designed to be visually pleasing while still providing an overview of the terrain of a ski resort. READ MORE

  5. 4. Urban Growth and Environmental Risks - A GIS-Based Analysis of Landslide Susceptibility in Bukavu (Democratic Republic of the Congo)

    University essay from Umeå universitet/Institutionen för geografi

    Author : Simon Paul; [2019]

    Abstract : The city of Bukavu, located at the eastern border of the Democratic Republic of Congo in the province of South Kivu, is a large and densely populated urban agglomeration that has experienced rapid growth during recent years. At the same time, Bukavu has been repeatedly struck by environmental hazards, especially by devastating landslides. READ MORE

  6. 5. 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.
