  • 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 ...
  • Alrajhi, M.N.; Jacobsen, Karsten; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    The General Directorate of Surveying and Mapping (GDSM), under the Ministry of Municipal and Rural Affairs (MOMRA) is responsible for the production and dissemination of accurate geospatial data for all the metropolitan ...
  • Passini, Ricardo; Jacobsen, Karsten (London : International Society for Photogrammetry and Remote Sensing, 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 ...
  • 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 ...
  • Dennig, Dirk; Bureick, Johannes; Link, Johannes; Diener, Dmitri; Hesse, Christian; Neumann, Ingo (Basel : MDPI AG, 2017)
    The process of surveying crane runways has been continually refined due to the competitive situation, modern surveying instruments, additional sensors, accessories and evaluation procedures. Guidelines, such as the ...
  • Li, Yinan; Bossmeyer, Hagen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Common 2D laser line triangulation sensors allow a 2D profile measurement in a single line. To scan samples with great curved surfaces like edges, a single laser line triangulation sensor is insufficient. To measure the ...

    Restoration efforts in the Mediterranean Basin have been changing from a silvicultural to an ecological restoration approach. Yet, to what extent the projects are guided by ecological restoration principles remains largely ...
  • Sefercik, Umut Gunes; Sörgel, Uwe (London : International Society for Photogrammetry and Remote Sensing, 2010)
    SAR Interferometry (InSAR) is a technique to derive Digital Elevation Model (DEM) from at least two complex SAR images. The data are either taken simultaneously (single-pass mode) or sequentially (repeat-pass mode) by ...
