  • Analysis and correction of systematic height model errors 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2016)
    The geometry of digital height models (DHM) determined with optical satellite stereo combinations depends upon the image orientation, influenced by the satellite camera, the system calibration and attitude registration. ...
  • Characteristics and accuracy of large area covering height models 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 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 ...
  • Development of large area covering height model 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2014)
    Height information is a basic part of topographic mapping. Only in special areas frequent update of height models is required, usually the update cycle is quite lower as for horizontal map information. Some height models ...
  • Geometric accuracy analysis of worlddem in relation to AW3D30, srtm and aster GDEM2 
    Bayburt, S.; Kurtak, A.B.; Büyüksalih, G.; Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2017)
    In a project area close to Istanbul the quality of WorldDEM, AW3D30, SRTM DSM and ASTER GDEM2 have been analyzed in relation to a reference aerial LiDAR DEM and to each other. The random and the systematic height errors ...
  • Mapping biomass availability to decrease the dependency on fossil fuels 
    Steensen, Torge; Müller, S.; Jandewerth, M.; Büscher, O. (Göttingen : Copernicus GmbH, 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. ...
  • Pléiades project: Assessment of georeferencing accuracy, image quality, pansharpening performence and DSM/DTM quality 
    Topan, H.; Cam, A.; Özendi, M.; Oruç, M.; Jacobsen, Karsten; Taşkanat, T. (Göttingen : Copernicus GmbH, 2016)
    Pléiades 1A and 1B are twin optical satellites of Optical and Radar Federated Earth Observation (ORFEO) program jointly running by France and Italy. They are the first satellites of Europe with sub-meter resolution. Airbus ...
  • Point-based and model-based geolocation analysis of airborne laser scanning data 
    Sefercik, Umut Gunes; Buyuksalih, Gurcan; Jacobsen, Karsten; Alkan, Mehmet (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Airborne laser scanning (ALS) is one of the most effective remote sensing technologies providing precise three-dimensional (3-D) dense point clouds. A large-size ALS digital surface model (DSM) covering the whole Istanbul ...
  • Problems and limitations of satellite image orientation for determination of height models 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2017)
    The usual satellite image orientation is based on bias corrected rational polynomial coefficients (RPC). The RPC are describing the direct sensor orientation of the satellite images. The locations of the projection centres ...
