  1. 1. 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.

  3. 2. Looking for shrubs in an alvar: Investigating classification of orthophotos as a way of mapping shrub species Juniperus communis and Dasiphora fruticose on Stora Alvaret, Öland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Lantmäteri (CI)

    Author : Jorun Westman; [2022]
    Keywords : Physical Geography; Orthophoto; Stora Alvaret; Shrub; Monitoring; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : Loss of biodiversity is an immediate threat to the planet and if no actions are taken it is expected to accelerate. The highest species richness on smaller scale is found in semi-natural temperate grasslands, with one of the documented records from Stora Alvaret on Öland, Sweden. READ MORE

  4. 3. Glacial history of the upper Drac Blanc catchment (French Alps)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Keywords : Physical Geography; 10Be exposure dating; structure-from motion; geomorphological mapping; moraine; equilibrium line altitude; Alps; Earth and Environmental Sciences;

    Abstract : Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. READ MORE

  5. 4. Real-time image processing on handheld devices and UAV

    University essay from Linköpings universitet/Institutionen för datavetenskap
