  1. 1. FROM SPACE TO THE SUBSURFACE. Examining Relations Between Vegetation Indices and Local Groundwater Storage.

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Gustav Antonsson; [2023-11-06]
    Nyckelord :;

    Sammanfattning : This study aimed to examine the relationship between vegetation indices, NDVI and NDWI, and groundwater levels in the county of Kalmar, utilizing correlation and regression analysis. Further, by examining related geospatial features the study aimed to interpret the statistical outcomes to identify significant temporal and spatial patterns. LÄS MER

  3. 2. Deep Neural Networks for Object Detection in Satellite Imagery

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Frederik Fritsch; [2023]
    Nyckelord :Object Detection; Satellite Imagery; Deep Neural Networks; YOLOv8; xView;

    Sammanfattning : With the development of small satellites it has become easier and cheaper to deploy satellites for earth observation from space. While optical sensors capture high-resolution data, this data is traditionally sent to earth for analysis which puts a high constraint on the data link and increases the time for making data based decisions.

  4. 3. Procedural Natural Texture Generation on a Global Scale

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Anna Pohl Lundgren; [2023]
    Nyckelord :computer graphics; procedural generation; procedural textures; gpu; image processing; satellite imagery; real time; real-time; shadow detection;

    Sammanfattning : This Master’s thesis investigates the application of dynamically generated procedural terrain textures for texturing 3D representations of the Earth’s surface. The study explores techniques to overcome limitations of the currently most common method – projecting satellite imagery onto the mesh – such as insufficient resolution for close-up views and challenges in accommodating external lighting models.

  5. 4. From space to place

    Master-uppsats, Göteborgs universitet/HDK-Valand - Högskolan för konst och design

    Författare :Charlotta Gavelin; [2022-06-02]
    Nyckelord :;

    Sammanfattning : In this essay, I have discussed a number of choices made through a photographic field work about a chosen place. By considering the archive as a space with a possible built in creative intensity, archive material intertwined with contemporary findings become an active part in understanding the present in an ongoing narrative.

  7. 5. Mapping Fire Salamander (Salamandra salamandra) Habitat Suitability in Baden-Württemberg with Multi-Temporal Sentinel-1 and Sentinel-2 Imagery

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Andreas Eriksson; [2022]
    Nyckelord :Geography; GIS; Habitat Suitability; Remote Sensing; Image Classification; Earth and Environmental Sciences;

    Sammanfattning : Remote sensing image classification is used in land cover, forest type and tree species classifications but rarely considered for habitat suitability modelling of animal and plant species. It is instead common that land cover products derived from remote sensing data are used in these modelling problems, even though satellite imagery can provide more detailed information. LÄS MER
