  1. 11. Inferring Land Use from Remote Sensing Imagery A context-based approach

    University dissertation from Stockholm : Department of Human Geography, Stockholm University

    Author : Michael Meinild Nielsen; Stockholms universitet.; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land use; remote sensing; urban remote sensing; image analysis; segmentation; spatial context; land cover; land cover configuration; farming types; bark beetle; dead trees; forest inventory; Human Geography; kulturgeografi;

    Abstract : This doctoral thesis investigates the potential of classification methods based on spatial context to infer specific forms of land use from remote sensing data. The problem is that some types of land use are characterized by a complex configuration of land covers that traditional per-pixel based methods have problems classifying due to spectral heterogeneity.

    Abstract : This PhD study focusses on the use of MEdium Resolution Imaging Spectrometer (MERIS) data for reliable and quantitative water-quality assessment of optically-complex waters (lake, brackish and coastal waters). The thesis is divided into two parts: A. READ MORE

  3. 13. GNSS Radio Occultation Inversion Methods and Reflection Observations in the Lower Troposphere

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Thomas Sievert; Blekinge Tekniska Högskola.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS Radio Occultation GNSS-RO ;

    Abstract : GNSS Radio Occultation (GNSS-RO) is an opportunistic Earth sensing technique where GNSS signals passing through the atmosphere are received in low Earth orbit and processed to extract meteorological parameters. As signals are received along an orbit, the measured Doppler shift is transformed to a bending angle profile (commonly referred to as bending angle retrieval), which, in turn, is inverted to a refractivity profile.

  4. 14. Urban Area Information Extraction From Polarimetric SAR Data

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Deliang Xiang; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polarimetric SAR; Scattering Decomposition; Man-Made Target Detection; Edge Detection; Superpixel; Urban Classification; Polarimetrisk SAR; Spridningsnedbrytning; Upptäckt av artificiella objekt; Kantupptäckt; Superpixel; Urban klassificering; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Polarimetric Synthetic Aperture Radar (PolSAR) has been used for various remote sensing applications since more information could be obtained in multiple polarizations. The overall objective of this thesis is to investigate urban area information extraction from PolSAR data with the following specific objectives: (1) to exploit polarimetric scattering model-based decomposition methods for urban areas, (2) to investigate effective methods for man-made target detection, (3) to develop edge detection and superpixel generation methods, and (4) to investigate urban area classification and segmentation.

  5. 15. Images from unmanned aircraft systems for surveying aquatic and riparian vegetation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Eva Husson; Sveriges lantbruksuniversitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Aquatic and riparian vegetation in lakes, streams, and wetlands has important ecological and regulatory functions and should be monitored to detect ecosystem changes. Field surveys are often tedious and in countries with numerous lakes and streams a nationwide assessment is difficult to achieve. READ MORE
