  1. 1. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

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

    Författare :Maximilian Rafael Huber; [2021]
    Nyckelord :physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. LÄS MER

  3. 2. Analysis of coastal erosion between different flights of UAV

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

    Författare :Zhengran Yin; [2021]
    Nyckelord :Coastal erosion; UAV; Digital Surface Model; Slope; Elevation differences; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : More than 600 million people are living in coastal areas in the world. According to the trend of population migration, the global coastal area population may increase to more than 1 billion by 2050. LÄS MER

  4. 3. A Case Study to develop and test GIS/SDSS methods to assess the production capacity of a Cocoa Site in Trinidad and Tobago

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

    Författare :Pritam Kumarsingh; [2021]
    Nyckelord :geography; GIS; MCA; Fuzzy; AHP; cocoa; SDSS; crop; management; climate; soil; agriculture; production; LGP; Trinidad; Tobago; Earth and Environmental Sciences;

    Sammanfattning : Pritam Kumarsingh A Case Study to develop and test GIS/SDSS methods to assess the production capacity of a Cocoa Site in Trinidad and Tobago Trinidad and Tobago has achieved world-wide affirmation for its unique fine and flavour cocoa (Theobroma cacao). This classification of cocoa commands price premiums on the global market. LÄS MER

  5. 4. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

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

    Författare :Oskar Evert Johansson; [2021]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Sammanfattning : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. LÄS MER

  7. 5. Soil erosion by water : Estimating soil loss and sediment yield in the southern half of Sweden by using the Revised Universal Soil Loss (RUSLE) model

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ella Myr; [2021]
    Nyckelord :Soil erosion; water erosion; soil loss; RUSLE; rainfall erosivity; soil erodibility;

    Sammanfattning : Soil erosion has been recognized as an increasing threat to the environment and humans worldwide as anthropogenic activities have accelerated the soil degradation rate. In Sweden, it is estimated that 15% of the arable land is affected by soil erosion, and studies have shown that fields in the south of Sweden lose a substantial amount of soil under certain weather conditions.
