  1. 11. Comparison of forest fire severity classification models based on aerial images and Landsat 8 OLI/TIRS images of a forest fire area in central Sweden

    Master-uppsats, SLU/Dept. of Forest Resource Management

    Författare :Adrian Straker; [2016]
    Nyckelord :forest fire; fire severity; stereo photogrammetry; digital surface model; aerial images; NDVI; NBR; Image Matching; Västmanland;

    Sammanfattning : Due to different level of fire severity a diverse mosaic of vegetation pattern establishes after the occurrence of a forest fire. In order to study the effects of forest fires and to plan future remediation of the burned area remote assessment of forest fire severity has shown to be a valuable tool. LÄS MER

  2. 12. Forest Change Mapping in Southwestern Madagascar using Landsat-5 TM Imagery, 1990 –2010

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Jeroen Grift; [2016]
    Nyckelord :Deforestation; pixel-based classification; object-based classification; landscape metrics; scaling structure;

    Sammanfattning : The main goal of this study was to map and measure forest change in the southwestern part of Madagascar near the city of Toliara in the period 1990-2010. Recent studies show that forest change in Madagascar on a regional scale does not only deal with forest loss, but also with forest growth However, it is unclear how the study area is dealing with these patterns.

  3. 13. Measuring urban growth, urban form and accessibility as indicators of urban sprawl in Hamilton, New Zealand

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

    Författare :Deborah Bowyer; [2015]
    Nyckelord :GIS; urban sprawl; urban growth; urban form; accessibility; New Zealand; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Sammanfattning : Hamilton City is currently the fourth most populous territorial authority in New Zealand. The city boundary was extended in 1989 in order to provide sufficient land for urban growth for at least 25 years. Despite being neither unplanned nor unchecked, urban growth within this boundary has been branded by the media as urban sprawl. LÄS MER

  4. 14. Forestry Carbon Sequestration and Trading: a Case study of Mau Forest Complex in Kenya

    Magister-uppsats, Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :Kevine Okoth Otieno; [2015]
    Nyckelord :carbon; indices; NDVI; change detection; biomass; remote sensing;

    Sammanfattning : The global temperature is at an all-time high, the polar ice is melting, the sea levels are rising and the associated disasters are a time bomb. These variations in temperature are thought to trace roots to anthropogenic sources. LÄS MER

  5. 15. Reaching the 2014 UN New York Declaration on Forests Goals, using satellites to monitor global value chains

    Master-uppsats, Stockholms universitet/Kulturgeografiska institutionen

    Författare :Rickard Näsström; [2015]
    Nyckelord :Remote Sensing; CSR; Value chains; Deforestation NDVI; WICS.;

    Sammanfattning : This master thesis in geography investigates how remote sens- ing can be used in Transnational Corporations (TNC) global Corporate Social Responsibility (CSR) initiatives. The study aims to delineate an accurate method in remote sensing to be used to monitor deforestation in global value chains. LÄS MER
