  1. 1. Smarter geovisualization tools : a user approach

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

    Författare :Frida Ulfves; [2019]
    Nyckelord :physical geography and ecosystem analysis; geography; geovisualizations; sense of place; user approach; Earth and Environmental Sciences;

    Sammanfattning : Geovisualization tools are continuously becoming more complex. These tools can present vivid and highly accurate representations of the real world. Simultaneously, spatial data is becoming incredibly detailed and the possibilities of interacting with the geovisualization tools are plentiful. Geovisualization tools are indeed powerful. LÄS MER

  2. 2. RGB and Multispectral UAV image classification of agricultural fields using a machine learning algorithm

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

    Författare :Sigurbjörn Jónsson; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; UAV; classification; Random Forest; Geomatics; segmentation; Earth and Environmental Sciences;

    Sammanfattning : A common technique within image analysis is image classification which describes the process of reducing the information content of an image into few user-defined classes. With the emergence of unmanned aerial vehicles (UAVs), high spatial resolution (cm-level) images can be collected. LÄS MER

  3. 3. UAV based hyperspectral grassland monitoring in an alpine shallow erosion area : lessons learnt from classifying vegetation indicating shallow erosion risk

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

    Författare :John Peitz; [2019]
    Nyckelord :Physical Geography; Ecosystem Analysis; Shallow Erosion; Blaiken; UAV; Hyperspectral Imaging; Alps; Grassland; Spectral Signatures; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : UAV based hyperspectral grassland monitoring in an alpine shallow erosion area Recent research in the Alps found that a reduction in grassland management is correlated to an increase in a certain type of shallow erosion areas called blaiken. This change also entails changes to the dominant grassland vegetation. LÄS MER

  4. 4. Constructing and developing an integrated smart spatial database for Malmö Municipality : case study : Västra innerstaden in Malmö

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

    Författare :Sayed Hassan Alavi; [2018]
    Nyckelord :Physical Geography and Ecosystem analysis; GIS section of street and park department of Malmö Municipality; consistency; integration; iTRIMAN; traffic database; smart database; geomatics; Earth and Environmental Sciences;

    Sammanfattning : GIS Section of Street and Park department of Malmö Municipality continuously receives new spatial data from different contractors that need to be saved to the GIS section traffic database. Due to spatial relationships and daily updates of traffic database, it is evident that the traffic database requires more consistency and integration in an automatic way. LÄS MER

  5. 5. Mapping tree canopy cover in the semi-arid Sahel using satellite remote sensing and Google Earth imagery

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

    Författare :Abdalla Eltayeb Abdalla Mohamed; [2017]
    Nyckelord :Sahel; physical geography and ecosystem analysis; tree cover; NDVI; Google Earth; Landsat 8; geomatics; Earth and Environmental Sciences;

    Sammanfattning : Tree vegetation is an essential element in the daily life of the people in the Sahel region of Africa. It is also considered as a robust indicator of the Sahel ecosystem status and health. In this thesis, a method to estimate tree vegetation was developed and used in mapping the tree canopy cover in semi-arid Sahel. LÄS MER
