  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. Glacier front variatons in Sweden: 2015-2022

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Martin Houssais; [2023]
    Keywords : Swedish glaciers; Glacier front variation; Remote sensing; MaQiT; Sentinel-2; Handheld GNSS; UAV photogrammetry; Total station;

    Abstract : This study aims at increasing the amount of data available on recent past Swedish glacier front variations, at improving the knowledge on the present behavior of these glaciers, and at contributing to the defnition of the guideline for future of glacier front observations in Sweden. To do so, the study proposes Sentinel-2 based yearly front variation measurements for 22 Swedish glaciers between 2015 and 2022, calculated based on the multicentreline approach of the MaQiT tool.

  4. 3. Developing a Geographical Information System for a water and sewer network, for monitoring, identification and leak repair - Case study: Municipal Water Company of Naoussa, Greece

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Konstantinos Sourlamtas; [2023]
    Keywords : Water and sewer network; GIS; UAV; surveying; photogrammetry; orthophoto; geodatabase; Earth and Environmental Sciences;

    Abstract : This thesis presents the design and implementation of a Geographic Information System (GIS) for the Naoussa Municipality Water and Sewer Company for better water utility management. The methodology contained field data collection like the valves, sewer manholes, hydrometers, and hydrants in two ways, UAV photogrammetry, and traditional surveying, the georeferencing process, photogrammetric processing, the digitization of old paper maps and the geodatabase design.

  5. 4. Nya perspektiv: drönarteknologi för landskapsarkitekter : en undersökning av hur drönare fungerar och hur de kan användas för att studera landskap

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Philip Wingård; [2022]
    Keywords : drönare; UAV; UAS; landskapsarkitektur; fotogrammetri; ; SfM; punktmoln; ortomosaik; drönarfoto;

    Abstract : As consumer grade drones are becoming increasingly accessible and technically refined, a growing number of professionals are taking advantage of the capabilities offered by drone technology. The potential for landscape architecture may seem obvious and the possibilities of seeing the world from above, at the user's convenience, should make it a tool sought-after by landscape architects.

  6. 5. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maximilian Rafael Huber; [2021]
    Keywords : physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Abstract : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. READ MORE
