  1. 21. Mapping Lupinus nootkatensis in Iceland using SPOT 5 images

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Arna Björk Thorsteinsdottir; [2011]
    Keywords : alien invasive species; physical geography; remote sensing; unsupervised classification; maximum likelihood classification; geography; Earth and Environmental Sciences;

    Abstract : Frön och rötter från Lupinus nootkatensis infördes till Island år 1945 med syftet att undersöka artens potential att bidra till återställandet av eroderad mark. Arten, som ursprungligen kommer från Alaska, visade sig vara mycket effektiv i samband med detta och dessutom kostnadseffektiv. READ MORE

  3. 22. Comparison and Fusion of space borne L-, C- and X- Band SAR Images for Damage Identification in the 2008 Sichuan Earthquake

    University essay from KTH/Geodesi och geoinformatik

    Author : SIN WAI LAU; [2011]
    Keywords : Remote sensing; SAR; image fusion; Sichuan earthquake; PALSAR; RADARSAT-1; TerraSAR-X;

    Abstract : Remote sensing has been widely used in disaster management. However, application of optical imageries in damage detection is not always feasible for immediate damage assessment. In the case of the Sichuan earthquake in 2008, the damaged areas were covered by cloud and fog for most of the time. READ MORE

  4. 23. Mauritania and Senegal coastal area urbanization, ground water flood risk in Nouakchott and Land use/land cover change in Mbour area

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Adama Ouattara; [2011]
    Keywords : geography; physical geography; urban area expansion; coastal area; population; ground water flood; land cover land use; normalized difference vegetation index; geographical information system; remote sensing.; Earth and Environmental Sciences;

    Abstract : Urbanization has increased significantly in Mauritania and Senegal during the last decades since the countries gained independence. In both countries most of the important cities are located in their coastal area. Cities inherited from the colonial period expand both in size and inhabitants. READ MORE

  5. 24. The potential of support vector machine classification of land use and land cover using seasonality from MODIS satellite data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Florian Sallaba; [2011]
    Keywords : geography; geomatics; remote sensing; MODIS; support vector machine; phenology; TIMESAT; geografi; geomatik; fjärranalys; fenologi; Earth and Environmental Sciences;

    Abstract : With respect to climate change it is necessary to study land use and land cover (LULC) and their changes. LULC are related directly and indirectly to climatic changes such as rising temperatures that trigger earlier onset of vegetation growing seasons (IPCC 2007). READ MORE

  6. 25. Multitemporal Satellite Images for Urban Change Detection

    University essay from KTH/Geodesi och geoinformatik
