  • 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 ...
  • 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 ...
  • 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 ...
  • Comprehensive and highly accurate measurements of crane runways, profiles and fastenings 
    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 ...
  • Development of an edge sensor based on polyview optics and laser triangulation principle 
    Li, Yinan; Bossmeyer, Hagen; Kästner, Markus; Reithmeier, Eduard (Bellingham, Wash. : SPIE, 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 ...
  • Ecological restoration across the Mediterranean Basin as viewed by practitioners 
    Nunes, Alice; Oliveira, Graca; Mexia, Teresa; Valdecantos, Alejandro; Zucca, Claudio; Costantini, Edoardo A.C.; Abraham, Eleni M.; Kyriazopoulos, Apostolos P.; Salah, Ayman; Prasse, Rüdiger; Correia, Otilia; Milliken, Sarah; Kotzen, Benz; Branquinho, Cristina (Amsterdam : Elsevier, 2016)
    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 ...
  • A procedure for semi-automatic orthophoto generation from high resolution satellite imagery 
    Alrajhi, M.N.; Jacobsen, Karsten; Heipke, Christian (Göttingen : Copernicus GmbH, 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 ...
  • Topographic estimation by TERRASAR-X 
    Sefercik, Umut Gunes; Sörgel, Uwe (Göttingen : Copernicus GmbH, 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 ...
