  1. 1. Urban tree canopy mapping -an open source deep learning approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Rydlinge; [2023]
    Keywords : Geography; GIS; AI; deep learning; urban trees; remote sensing; Earth and Environmental Sciences;

    Abstract : Urban trees have an important role to provide ecosystem services and to make our cities greener and more sustainable. The changing climate and densification of cities make it even more valuable to preserve and investigate in urban trees. READ MORE

  3. 2. Compression of Large-Scale Aerial Imagery : Exploring Set Redundancy Methods

    University essay from Högskolan i Gävle/Datavetenskap

    Author : Solvej Lüdeking; [2023]
    Keywords : Set redundancy; image compression; aerial imagery;

    Abstract : Compression of data has been historically always important; more data is gettingproduced and therefore has to be stored. While hardware technology advances,compression should be a must to reduce storage occupied and to keep the data intransmission as small as possible. READ MORE

  4. 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

  5. 4. All scales matter : effects on the landscape-, stand-, substrate- and temporal scale on occurrence of two deadwood living microlichens

    University essay from SLU/Dept. of Ecology

    Author : Edith Bremer; [2021]
    Keywords : extinction debt; deadwood; microlichens; continuity forest; landscape structure;

    Abstract : Understanding extinction debt and how species are affected by landscape structure is important knowledge in order to form strategies for species protection in forestry and conservation. In this study, I investigate whether an extinction debt can be detected in two deadwood living lichen species by modelling their occurrence against past and present habitat amount in the landscape as well as amount of continuity forest (i.

  6. 5. Studie av glaciärer i Sarek nationalpark under 60 år med flygbilder som underlag

    University essay from SLU/Dept. of Forest Resource Management

    Author : Albin Bjärhall; [2020]
    Keywords : glaciärer; avsmältning; klimatförändring; flygbilder; ortofoton; 3D-modellering;

    Abstract : De senaste årens ökade debatt kring pågående klimatförändringar har lett till att allt mer uppmärksamhet har riktats mot världens glaciärer och hur de påverkas av vår övergång mot ett varmare klimat. I denna studie används ortofoton samt en höjdmodell genererade av Lantmäteriets flygbilder från 1960-talet och framåt som grund för att undersöka hur ett urval av glaciärer i Sarek nationalpark har förändrats med hänsyn till area och volym under de senaste 60 åren.
