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. Correlation of Magma Intrusions in the Slaufrudalur Pluton With 3D Modeling and Photogrammetry

   University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

   Author : Maximilian Solberg; [2022]
   Keywords : photogrammetry; pluton; intrusion; subterranean cauldron subsidence; point cloud; mesh; geocellular volume; fotogrammetri; pluton; intrusion; subterranean cauldron subsidence; point cloud; mesh; geocellular volume;

   Abstract : Photogrammetry has become a great tool when analyzing geological outcrops. The Slaufrudalur plutonis located in southeast Iceland and is composed of multiple granitic intrusions. READ MORE

5. 4. 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

6. 5. Multi-method based characterization of calving events at Sálajiegna Glacier - Lake Sulitelma, Northern Sweden

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Martin Schulthess; [2021]
   Keywords : Glaciology; Glacier; Glaciers; Calving; calving front; detection algorithm; Acoustic; Acoustics; Photogrammetry; ice-ocean interactions; UAV; drone; time-lapse; Salajiegna;

   Abstract : Sea level rise concerns millions of people in coastal areas across the globe. One of the largest uncertainties to project future sea level rise is the frontal ablation (accounting for calving and submarine melt) at marine ice margins, around the Greenland and Antarctic Ice Sheet.
