  1. 11. Satellite Monitoring of Urbanization and Indicator-based Assessment of Environmental Impact

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dorothy Furberg; Yifang Ban; Xiaojun Yang; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urbanization; remote sensing; land-cover classification; landscape metrics; environmental indicators; environmental impact; ecosystem services; green infrastructure; habitat network analysis; Greater Toronto Area; Stockholm; Shanghai; urbanisering; fjärranalys; marktäckeklassificering; landskapsnyckeltal; miljöindikatorer; miljöpåverkan; ekosystemtjänster; grön infrastruktur; habitat nätverksanalys; Greater Toronto Area; Stockholm; Shanghai; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geoinformatik; Geoinformatics;

    Abstract : As of 2018, 55% of the world population resides in urban areas. This proportion is projected to increase to 68% by 2050 (United Nations 2018). The Stockholm region is no exception to this urbanizing trend: the population of Stockholm City has risen by 28% since the year 2000. READ MORE

  2. 12. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data

    University dissertation from Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science

    Author : Abdulhakim Abdi; [2017-02]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Net Primary Production NPP ; Africa; Drylands; Coupled Human and Natural Systems; Human-Environment Relations; Food; Fuel; Feed; Earth Observation; Remote Sensing; Biomass; Carbon; Supply and Demand;

    Abstract : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. READ MORE

  3. 13. Temporal Characteristics of Boreal Forest Radar Measurements

    University dissertation from Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science

    Author : Albert Monteith; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; backscatter; tomography; Synthetic aperture radar; remote sensing; temporal coherence; antenna array;

    Abstract : Radar observations of forests are sensitive to seasonal changes, meteorological variables and variations in soil and tree water content. These phenomena cause temporal variations in radar measurements, limiting the accuracy of tree height and biomass estimates using radar data. READ MORE

  4. 14. Urban Change Detection Using Multitemporal SAR Images

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Osama Yousif; Yifang Ban; Lorenzo Bruzzone; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change detection; High resolution; Image denoising; Kittler-Illingworth; MAP-MRF; Multitemporal SAR images; Nonlocal means; Object-based; Otsu; Outlier detection; Remote sensing; SAR speckle; Urban; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.

  5. 15. Remote Sensing and GIS Applications for Groundwater Potential Assessment in Eritrea

    University dissertation from Stockholm : Byggvetenskap

    Author : Semere Solomon; [2003]
    Keywords : Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

    Abstract : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. READ MORE
