  2. 1. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

    Author : Xin Niu; Yifang Ban; Paolo Gamba; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RADARSAT-2; spaceborne; polarimetric SAR; urban land cover; classification; Information technology; Informationsteknik;

    Abstract : Urban represents one of the most dynamic areas in the global change context. To support rational policies for sustainable urban development, remote sensing technologies such as Synthetic Aperture Radar (SAR) enjoy increasing popularity for collecting up-to-date and reliable information such as urban land cover/land-use.

  4. 2. Multitemporal Spaceborne Polarimetric SAR Data for Urban Land Cover Mapping

    Author : Xin Niu; Yifang Ban; Laurent Ferro-Famil; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RADARSAT-2; Spaceborne; Polarimetric SAR; Urban Land cover; Object-based Rule-based Classification; Support Vector Machines; Contextual; Stochastic Expectation-Maximization; Markov Random Field.;

    Abstract : Urban land cover mapping represents one of the most important remote sensing applications in the context of rapid global urbanization. In recent years, high resolution spaceborne Polarimetric Synthetic Aperture Radar (PolSAR) has been increasingly used for urban land cover/land-use mapping, since more information could be obtained in multiple polarizations and the collection of such data is less influenced by solar illumination and weather conditions.

  6. 4. Spaceborne SAR Interferometry: Theory and Applications

    Author : Patrik Dammert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents the theoretical basis and system model for interferometric synthetic aperture radar, INSAR, from spaceborne platforms. The model describes how the images are formed and what relevant ground parameters affect the signal. There are several useful ground parameters in spaceborne INSAR data. READ MORE

  7. 5. Urban Land-cover Mapping with High-resolution Spaceborne SAR Data

    Author : Hongtao Hu; Yifang Ban; Johan Fransson; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; High-resolution; RADARSAT-1 SAR; RADARSAT-2 SAR; Urban Land Cover; Object-based Classification; Neural Network; Support Vector Machines.; Remote sensing; Fjärranalys;

    Abstract : Urban areas around the world are changing constantly and therefore it is necessary to update urban land cover maps regularly. Remote sensing techniques have been used to monitor changes and update land-use/land-cover information in urban areas for decades. Optical imaging systems have received most of the attention in urban studies. READ MORE
