    Height models are basic information required for disaster Management. Not in any case satisfying and actual height models are available, but they can be generated by satellite stereo pairs being more precise as InSAR. The ...
  • Wang, Jin (Basel : MDPI AG, 2013)
    Fine registration of point clouds plays an important role in data analysis in Terrestrial Laser Scanning (TLS). This work proposes a block-to-point fine registration approach to correct the errors of point clouds from TLS ...
  • Jacobsen, Karsten; Topan, H. (Hannover : International Society for Photogrammetry and Remote Sensing, 2015)
    An image triplet of Pleiades images covering the area of Zonguldak, Turkey has been investigated. The height to base relation of the first to the last image is just 1:4.5 and for the first and the second image 1:9. This ...
  • Jacobsen, Karsten (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Height information is a basic part of topographic mapping. Only in special areas frequent update of height models is required, usually the update cycle is quite lower as for horizontal map information. Some height models ...
  • Bayburt, S.; Kurtak, A.B.; Büyüksalih, G.; Jacobsen, Karsten (London : International Society for Photogrammetry and Remote Sensing, 2017)
    In a project area close to Istanbul the quality of WorldDEM, AW3D30, SRTM DSM and ASTER GDEM2 have been analyzed in relation to a reference aerial LiDAR DEM and to each other. The random and the systematic height errors ...
  • Jacobsen, Karsten (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Based on test blocks and standard production blocks Z/I Imaging DMCII-140, 230 and 250 as well as UltraCam Eagle images have been analyzed by bundle block adjustment with self calibration. By analysis of image coordinate ...
  • Jacobsen, Karsten (London : International Society for Photogrammetry and Remote Sensing, 2017)
    The usual satellite image orientation is based on bias corrected rational polynomial coefficients (RPC). The RPC are describing the direct sensor orientation of the satellite images. The locations of the projection centres ...
  • Jacobsen, Karsten; Gerke, M. (Göttingen : Copernicus GmbH, 2016)
    Penta cameras consisting of a nadir and four inclined cameras are becoming more and more popular, having the advantage of imaging also facades in built up areas from four directions. Such system cameras require a boresight ...
  • Jacobsen, K. (London : International Society for Photogrammetry and Remote Sensing, 2018)
    Very high resolution optical satellites are imaging the object space by a combination of CCD-lines in one direction and by time, speed and satellite rotation in the other direction. The combination of the CCD-lines usually ...
  • Unger, Jakob; Reich, Martin; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    The use of small-size unmanned aerial vehicles (UAV) for civil applications in many different fields such as archaeology, disaster monitoring, aerial surveying or mapping has significantly increased in recent years. The ...
