  • Dini, G.R.; Jacobsen, Karsten; Rottensteiner, Franz; Al Rajhi, M.; Heipke, Christian (Göttingen : Copernicus GmbH, 2012)
    In this paper, a workflow is proposed to detect 3D building changes in urban and sub-urban areas using high-resolution stereoscopic satellite images of different epochs and a GIS database. Semi-global matching (SGM) is ...
  • Wübbold, Frauke; Hentschel, Matthias; Vousdoukas, Michalis I.; Wagner, Bernardo (Reston : American Society of Civil Engineers, 2012)
    Beach topographic and hydrodynamic measurements are essential for coastal geology and engineering studies as well as sustainable coastal management. Standard approaches involve either time-consuming manual data acquisition ...
  • Song, Yujin; Niemeyer, Joachim; Ellmer, Wilfried; Sörgel, Uwe; Heipke, Christian (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Airborne laser bathymetry (ALB) can be used for hydrographic surveying with relative high resolution in shallow water. In this paper, we examine the applicability of this technique based on three flight campaigns. These ...
  • Matesanz, Philip; Graen, Timo; Fiege, Andrea; Nolting, Michael; Nejdl, Wolfgang (Basel : MDPI, 2021)
    Automakers manage vast fleets of connected vehicles and face an ever-increasing demand for their sensor readings. This demand originates from many stakeholders, each potentially requiring different sensors from different ...
  • Zhang, L.; Sester, Monika (Göttingen : Copernicus Publications, 2011)
    GPS traces can track actual time and coordinates of regular vehicles going their own business, and it is easy to scale to the entire area with an accuracy of 6 to 10 meters in normal condition. As a result, extracting road ...
  • Cefalu, A.; Haala, N.; Schmohl, S.; Neumann, I.; Genz, T. (London : International Society for Photogrammetry and Remote Sensing, 2017)
    Photogrammetric data capture of complex 3D objects using UAV imagery has become commonplace. Software tools based on algorithms like Structure-from-Motion and multi-view stereo image matching enable the fully automatic ...
  • Schmidt, Alena; Sörgel, Uwe (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    In coastal areas morphological changes of various kinds are caused by tidal flows, storms, climate change, and human activities. For these reasons a recurrent monitoring becomes necessary in order to detect undesired changes ...
  • Sörgel, Uwe; Jacobsen, Karsten; Schack, Lukas (Hannover : International Society for Photogrammetry and Remote Sensing, 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 ...
  • Altmann, Bettina; Pape, Christian; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Increasing requirements concerning the quality and lifetime of machine components in industrial and automotive applications require comprehensive investigations of the components in conditions close to the application. ...
