  • Global bundle adjustment with variable orientation point distance for precise mars express orbit reconstruction 
    Bostelmann, Jonas; Heipke, Christian (Katlenburg-Lindau : Copernicus Publications, 2016)
    The photogrammetric bundle adjustment of line scanner image data requires a precise description of the time-dependent image orientation. For this task exterior orientation parameters of discrete points are used to model ...
  • GPS-aided video tracking 
    Feuerhake, Udo; Brenner, Claus; Sester, Monika (Basel : MDPI AG, 2015)
    Tracking moving objects is both challenging and important for a large variety of applications. Different technologies based on the global positioning system (GPS) and video or radio data are used to obtain the trajectories ...
  • A graph based model for the detection of tidal channels using marked point processes 
    Schmidt, Alena; Rottensteiner, Franz; Sörgel, Uwe; Heipke, Christian (Göttingen : Copernicus GmbH, 2015)
    In this paper we propose a new method for the automatic extraction of tidal channels in digital terrain models (DTM) using a sampling approach based on marked point processes. In our model, the tidal channel system is ...
  • Gravity field modelling for optical clock comparisons 
    Denker, Heiner; Timmen, Ludger; Voigt, Christian (Prague : International Union of Geodesy and Geophysics (IUGG), 2015)
    A coordinated programme of clock comparisons is carried out within the EMRP-funded project “International Timescales with Optical Clocks” (ITOC), aiming at a validation of the uncertainty budgets of the new optical clocks ...
  • Hierarchical higher order crf for the classification of airborne lidar point clouds in urban areas 
    Niemeyer, Joachim; Rottensteiner, Franz; Sörgel, Uwe; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    We propose a novel hierarchical approach for the classification of airborne 3D lidar points. Spatial and semantic context is incorporated via a two-layer Conditional Random Field (CRF). The first layer operates on a point ...
  • Impact of Different Phase Center Correction Values on Geodetic Parameters: A Standardized Simulation Approach 
    Kröger, Johannes; Kersten, Tobias; Breva, Yannick; Brekenkamp, Mareike; Schön, Steffen (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022-05-24)
    For highly precise and accurate positioning and navigation solutions with GNSS, it is mandatory to take all error sources – including phase center corrections (PCC) – adequately into account. These corrections are provided ...
  • Improvements on near real time detection of volcanic ash emissions for emergency monitoring with limited satellite bands 
    Steensen, Torge; Webley, Peter; Dehn, Jon (Bologna : Editrice Compositori s.r.l., 2014)
    Quantifying volcanic ash emissions syneruptively is an important task for the global aviation community. However, due to the near real time nature of volcano monitoring, many parameters important for accurate ash mass ...
  • Influence of retention areas on the propagation of storm surges in the Weser estuary 
    Zorndt, Anna C.; Goseberg, Nils; Schlurmann, Torsten (Reston : American Society of Civil Engineers (ASCE), 2014)
    The hydrodynamics of estuaries are forced by the tides from the open sea and the river runoff from the catchment area. The hinterland is often low-lying and densely populated and must therefore be protected by dikes. ...
  • Integration of a generalised building model into the pose estimation of UAS images 
    Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    A hybrid bundle adjustment is presented that allows for the integration of a generalised building model into the pose estimation of image sequences. These images are captured by an Unmanned Aerial System (UAS) equipped ...

    Mouris, Kilian; Schwindt, Sebastian; Pesci, María Herminia; Wieprecht, Silke; Haun, Stefan ([London] : Macmillan Publishers Limited, part of Springer Nature, 2023)
    Global change alters hydro-climatic conditions, affects land use, and contributes to more frequent droughts and floods. Large artificial reservoirs may effectively alleviate hydro-climatic extremes, but their storage ...
  • Intersection detection based on qualitative spatial reasoning on stopping point clusters 
    Zourlidou, S.; Sester, Monika (Göttingen : Copernicus GmbH, 2016)
