  • 3D building change detection using high resolution stereo images and a GIS database 
    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 ...
  • Application of an autonomous robot for the collection of nearshore topographic and hydrodynamic measurements 
    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 ...
  • Comparison of three airborne laser bathymetry data sets for monitoring the German Baltic Sea Coast 
    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 ...
  • Demand-driven data acquisition for large scale fleets 
    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 ...
  • Incremental data acquisition from gps-traces 
    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 ...
  • A mobile multi-sensor platform for building reconstruction integrating terrestrial and autonomous UAV-based close range data acquisition 
    Cefalu, A.; Haala, N.; Schmohl, S.; Neumann, I.; Genz, T. (Göttingen : Copernicus GmbH, 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 ...
  • Monitoring and change detection of wadden sea areas using lidar data 
    Schmidt, Alena; Sörgel, Uwe (Göttingen : Copernicus GmbH, 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 ...
  • 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 ...
  • Temperature measurements on fast-rotating objects using a thermographic camera with an optomechanical image derotator 
    Altmann, Bettina; Pape, Christian; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 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. ...
  • A Versatile IoT-Approach to Process Data Acquisition 
    Behrens, Bernd-Arno; Krimm, Richard; Koß, Jonas; Höber, André (Liège : ULiège Library, 2021)
    The acquisition and evaluation of process data in production engineering holds great potential. This allows detecting faulty processes at an early stage and processes to be optimized even more efficiently. However, the use ...
  • Vulnerability of Smart Grid-enabled Protection Relays to IEMI 
    Arduini, Fernando; Lanzrath, Marian; Ghosalkar, Samikshya; Nateghi, Arash; Fisahn, Sven; Schaarschmidt, Martin (Göttingen : Copernicus Publications, 2023)
    The electricity sector has been undergoing transformations towards the smart grid concept, which aims to improve the robustness, efficiency, and flexibility of the power system. This transition has been achieved by the ...
