  • Accuracy analysis of digital orthophotos from very high resolution imagery 
    Passini, Ricardo; Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2004)
    The generation of digital Orthophotos now days can be done with aerial, but also very high resolution space imagery. For a real competition the geometric and radiometric quality has to be on the same level. Different ...
  • DEM generation with short base length pleiades triplet 
    Jacobsen, Karsten; Topan, H. (Göttingen : Copernicus GmbH, 2015)
    An image triplet of Pleiades images covering the area of Zonguldak, Turkey has been investigated. The height to base relation of the first to the last image is just 1:4.5 and for the first and the second image 1:9. This ...
  • DEM generation with worldview-2 images 
    Buyuksalih, Gurcan; Baz, I.; Alkan, Mehmet; Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2012)
    For planning purposes 42km coast line of the Black Sea, starting at the Bosporus going in West direction, with a width of approximately 5km, was imaged by WorldView-2. Three stereo scenes have been oriented at first by ...
  • 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 ...
  • Landsafe: landing site risk analysis software framework 
    Schmidt, R.; Bostelmann, Jonas; Cornet, Y.; Heipke, Christian; Philippe, C.; Poncelet, N.; De Rosa, D.; Vandeloise, Y. (Göttingen : Copernicus GmbH, 2012)
    The European Space Agency (ESA) is planning a Lunar Lander mission in the 2018 timeframe that will demonstrate precise soft landing at the polar regions of the Moon. To ensure a safe and successful landing a careful risk ...
  • Multi-temporal time-dependent terrain visualization through localized spatial correspondence parameterization 
    Dalyot, Sagi; Doytsher, Y. (Basel : MDPI AG, 2013)
    Visualizing quantitative time-dependent changes in the topography requires relying on a series of discrete given multi-temporal topographic datasets that were acquired on a given time-line. The reality of physical phenomenon ...
  • Multiple-model based update of belgian reference road data 
    Ziems, Marcel; Beyen, J.; Müller, Sönke; Roovers, S.; Heipke, Christian (Göttingen : Copernicus GmbH, 2011)
    This paper describes a semi-automatic system for road update based on high resolution orthophotos and 3D surface models. Potential update regions are identified by an object-wise verification of all existing database ...
  • TanDEM-X mission: Overview and evaluation of intermediate results 
    Sörgel, Uwe; Jacobsen, Karsten; Schack, Lukas (Göttingen : Copernicus GmbH, 2013)
    The German Aerospace Center (DLR, Deutsches Zentrum für Luft- und Raumfahrt) currently conducts the bistatic interferometric synthetic aperture radar (SAR) Mission TanDEM-X, which shall result in a DEM of global coverage ...
