  5. 19. Urban classification by pixel and object-based approaches for very high resolution imagery

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Fadi Ali; [2015]
    Nyckelord :Ancillary data; land use land cover classification; supervised algorithms; GIS; Remote sensing; OBIA;

    Sammanfattning : Recently, there is a tremendous amount of high resolution imagery that wasn’t available years ago, mainly because of the advancement of the technology in capturing such images. Most of the very high resolution (VHR) imagery comes in three bands only the red, green and blue (RGB), whereas, the importance of using such imagery in remote sensing studies has been only considered lately, despite that, there are no enough studies examining the usefulness of these imagery in urban applications.

  7. 20. Object-based Land Cover Classification with Orthophoto and LIDAR Data

    Master-uppsats, KTH/Geodesi och geoinformatik

    Författare :Yanjing Jia; [2015]
    Nyckelord :Object-based; Land cover classification; Orthophoto; LIDAR;

    Sammanfattning : Image classification based on remotely sensed data is the primary domain of automatic mapping research. With the increasing of urban development, keeping geographic database updating is imminently needed. Automatic mapping of land cover types in urban area is one of the most challenging problems in remote sensing. LÄS MER
