  1. 1. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

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

    Författare :Aleksandra Ivanova; [2019]
    Nyckelord :physical geography; ecosystem analysis; phenology; vegetation; climate change; remote sensing; plant phenology index; PPI; timesat; Balkan peninsula; Earth and Environmental Sciences;

    Sammanfattning : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. LÄS MER

  2. 2. Linking conflict events and cropland development in Afghanistan, 2001 to 2011, using MODIS land cover data and Uppsala Conflict Data Programme

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

    Författare :Gunnar Hesch; [2019]
    Nyckelord :geography; GIS; MODIS; Afghanistan; UCDP GED; cropland; conflict; Earth and Environmental Sciences;

    Sammanfattning : Linking conflict events and cropland development in Afghanistan, 2001 to 2011, using MODIS land cover data and Uppsala Conflict Data Programme This thesis describes changes in land cover between 2001 and 2011 in Afghanistan, and analyzes the influence of conflict events on cropland development. How did fighting intensity affect cropland areas in Afghanistan, did cropland areas decrease or increase, and were there regional differences in cropland development? Yearly MODIS (Moderate Resolution Imaging Spectroradiometer) land cover data have been used in this thesis work to assess cropland changes. LÄS MER

  3. 3. Fjällbjörkmätarlarvers påverkan på fjällbjörkskog : en fjärranalysstudie om markvegetationsförhållanden i subalpin miljö

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

    Författare :Melvin Moon; [2018]
    Nyckelord :Fjärranalys; NDVI; fjällbjörkmätare; Abisko; fjällbjörkskog; Earth and Environmental Sciences;

    Sammanfattning : Since the mid-1950s, studies have frequently been conducted on couplings between geometrid moth outbreaks and mountain birch, though not nearly as much focus has been on connections between geometrid moth outbreaks and ground cover. Previous studies have shown that major outbreaks of Epirrita autumnata occur in 9 – 10-year cycles (Karlsson et al. LÄS MER

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

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

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

    Sammanfattning : 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.

  5. 5. Identification and Masking Method of Clouds in Satellite Images

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Harsha Yashaskar Emani; [2018]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
