  3. 2. Inferring Land Use from Remote Sensing Imagery : A context-based approach

    Författare :Michael Meinild Nielsen; Bo Malmberg; Anders Wästfelt; Douglas A. Stow; Stockholms universitet; []
    Nyckelord :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; kulturgeografi; Human Geography;

    Sammanfattning : 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.
