  • Alrajhi, M.N.; Jacobsen, Karsten; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    The General Directorate of Surveying and Mapping (GDSM), under the Ministry of Municipal and Rural Affairs (MOMRA) is responsible for the production and dissemination of accurate geospatial data for all the metropolitan ...
  • Maas, Alina; Alrajhi, M.; Alobeid, A.; Heipke, Christian (London : International Society for Photogrammetry and Remote Sensing, 2017)
    Updating topographic geospatial databases is often performed based on current remotely sensed images. To automatically extract the object information (labels) from the images, supervised classifiers are being employed. ...
  • Büschenfeld, Torsten; Ostermann, Jörn (Göttingen : Copernicus GmbH, 2012)
    In this paper, we present a method for automatic refinement of training data. Many classifiers from machine learning used in applications in the remote sensing domain, rely on previously labelled training data. This labelling ...
  • Jacobsen, Karsten (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    Large area covering height models are dominantly based on optical and synthetic aperture radar (SAR) space imagery. The vertical accuracy of individual object points determined by automatic matching of optical imagery is ...
  • Dini, Gholam Reza; Jacobsen, Karsten; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    In this paper, a workflow is proposed to delineate building footprints from high resolution satellite stereo images through integration of a Digital Surface Model (DSM), 3D edge matching technique and GIS building polygons. ...
  • Leichter, Artem; Wittich, Dennis; Rottensteiner, Franz; Werner, Martin; Sester, Monika (London : International Society for Photogrammetry and Remote Sensing, 2018)
    In this work, we consider the exploitation of social media data in the context of Remote Sensing and Spatial Information Sciences. To this end, we explore a way of augmenting and integrating information represented by ...
  • Steensen, Torge; Müller, S.; Jandewerth, M.; Büscher, O. (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    To decrease the dependency on fossil fuels, more renewable energy sources need to be explored. Over the last years, the consumption of biomass has risen steadily and it has become a major source for re-growing energy. ...
  • Sefercik, Umut G.; Jacobsen, Karsten (Hannover : International Society for Photogrammetry and Remote Sensing, 2010)
    Radar remote sensing has a significant role in remote sensing technologies and develops rapidly. A series of new synthetic aperture radar (SAR) satellites has been launched to space having various operation modes which ...
  • Becker, Christian; Breitkopf, Uwe; Büschenfeld, Torsten; Busch, A.; Grünreich, D.; Heipke, Christian; Helmholz, Petra; Müller, S.; Ostermann, Jörn; Pahl, M.; Vogt, Karsten; Ziems, M. (London : International Society for Photogrammetry and Remote Sensing, 2010)
    The usefulness and acceptance of spatial information systems are mainly dependent on the quality of the underlying geodata. This paper describes a system for semiautomatic quality control of existing geospatial data via ...
