  1. 16. An open source web GIS tool for analysis and visualization of elephant GPS telemetry data, alongside environmental and anthropogenic variables

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Patrick Kabatha; [2018]
    Keywords : geography; GIS; web GIS; web mapping; open source; wildlife; elephant; ecology; time series; GPS telemetry; Biology and Life Sciences; Earth and Environmental Sciences;

    Abstract : The movement and distribution of ecologically important herbivores such as elephants are of great significance to conservation biologist seeking to understand the fundamental triggers that influence their mobility and the extent to which these parameters affect how they utilize their immediate and surrounding resources. The recent advancement in animal tracking technology coupled with the availability of moderate to high-resolution satellite data, permits scientists to develop elephant cognitive maps of their adjacent environment, thus offering novel opportunities for research in the fields of wildlife movement ecology and the wider conservation biology.

  2. 17. Developing Data Extraction and Dynamic Data Visualization (Styling) Modules for Web GIS Risk Assessment System (WGRAS)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Daniel Assefa; [2018]
    Keywords : Geographical Information Systems; GIS; Disaster Risk Management; web GIS; Volunteered Geographic Information VGI ; Map Visualization and styling; Geo-spatial data extraction; OpenStreetMap OSM ; Earth and Environmental Sciences;

    Abstract : Interactive web-GIS tools play an important role in determining disaster risk assessment which ultimately result in reduction of unexpected damages, cost and saves millions of lives. Disaster management practitioners largely benefited information at their disposal about location where possible incidents are eminent, anticipate the impact and project possible outcomes to help mitigate and organize proper response.

  4. 19. An evaluation of using GPM satellite products to forecast flash floods in mountainous catchments

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Yihan Chen; [2017]
    Keywords : GPM; Han River; Flood; IMERG; Mountain; Technology and Engineering;

    Abstract : NASA's GPM satellite rainfall products IMERG early run and IMERG late run were evaluated for their applicability in flash flood forecasting. The selected catchment was the upper Han River basin, a mountainous catchment with low precipitation in winter and heavy precipitation during summers located in central China. READ MORE

  5. 20. Identifying potential critical transitions in a forest ecosystem using satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Krishna Lamsal; [2017]
    Keywords : early warning; critical transition; tipping point; EVI; time series; GEM; Earth and Environmental Sciences;

    Abstract : Ecosystems can undergo changes that are slow and gradual, or an abrupt change - a sudden nonlinear dynamics that can bring catastrophic changes and ultimately leads to the change in the structure and functioning. Non-linear and discontinuous changes sometimes may cause the system to shift into another undesirable state, called ‘regime shifts’ or ‘critical transition’. READ MORE
