  1. 1. 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. 2. Identification and Masking Method of Clouds in Satellite Images

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Harsha Yashaskar Emani; [2018]
    Keywords : ;

    Abstract : Identification of the cloud in an image is essential in order to remove the noise in the image and improve the quality of the image. Further the masking of cloud in a satellite image is important in order to obtain a clear image taken from a remote sensing satellite. READ MORE

  3. 3. Study of spatial and temporal variation of atmospheric optical parameters and their relation with PM 2.5 concentration over Europe using GIS technologies

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Panagiotis Symeonidis; [2017]
    Keywords : aerosols; air quality; satellite remote sensing; GIS; geography; Geographical Information Systems; particulate matter; Aerosol Optical Depth; MODIS; Earth and Environmental Sciences;

    Abstract : The purpose of this study was to examine the use of remote sensing aerosol data as an estimator of ground level fine particulate matter concentration (PM 2.5). In order to examine this possible relation, daily MODIS Aerosol Optical Depth (AOD) data were used, collected for an entire year. READ MORE

  4. 4. Monitoring trends of greenness and LULC (land use/land cover) change in Addis Ababa and its surrounding using MODIS time-series and LANDSAT Data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tesfaye Gebeyehu Admasu; [2017]
    Keywords : Time-series; MODIS; Addis Ababa; Physical Geography and Ecosystem Science; NDVI; Greenness; LULC; GEM; Earth and Environmental Sciences;

    Abstract : NDVI(Normalized Difference Vegetation Index) was introduced in 1974. Despite its limitations, it has been under use for monitoring bio-physical and cultural landscapes from satellite. READ MORE

  5. 5. 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
