  1. 1. Wildfire growth modelling in Sweden - a suitability assessment of available data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Henrik Hagelin; [2023]
    Keywords : Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

    Abstract : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. READ MORE

  2. 2. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Colin Potter; [2023]
    Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  3. 3. 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. 4. ALS (Airborne Lidar) accuracy: Can potential low data quality of Lidar ground points be modelled/detected based on recorded point cloud characteristics? Case study of 2016 Lidar capture over Auckland, New Zealand

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Gabriela Olekszyk; [2022]
    Keywords : Geography; GIS; Lidar; ALS; Point cloud; Accuracy; Quality; Technology and Engineering;

    Abstract : Gabriela Olekszyk ALS (Airborne Lidar) accuracy: Can potential low data quality of Lidar ground points be modelled/detected based on recorded point cloud characteristics? Case study of 2016 Lidar capture over Auckland, New Zealand. Lidar (Light Detection and Ranging) data is becoming more widely available and accessible. READ MORE

  5. 5. Geometric comparison of 3D city models for daylight simulations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johannes Lande Nyborg; [2022]
    Keywords : Geography; Physical Geography; Ecosystem Analysis; 3D city model; 3D building models; daylight access; daylight simulations; obstruction angle; free and open-source software; sustainable urban development; Geomatics; Earth and Environmental Sciences;

    Abstract : As cities keep densifying, essential resources such as daylight access become increasingly restricted. Therefore, prioritizing energy efficiency and enhancing the energy performance of our buildings is required for obtaining a sustainable urban environment. READ MORE
