  • 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 ...
  • Stefanidis, Kostas; Ntoutsi, Eirini (Konstanz : OpenProceedings.org, 2016)
    In this work, we address the problem of contextual recommendations by exploiting the concept of subspace clustering. Specifically, we pre-partition users that have rated subsets of data items similarly into clusters and ...
  • Albert, Lena; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    The goal of this paper is to investigate the maximum level of semantic resolution that can be achieved in an automated land use change detection process based on mono-temporal, multi-spectral, high-resolution aerial image ...
  • Dini, Gholam Reza; Jacobsen, Karsten; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    In this paper, a workflow is proposed to delineate building footprints from high resolution satellite stereo images through integration of a Digital Surface Model (DSM), 3D edge matching technique and GIS building polygons. ...
  • Mantel, Daniela; Lipeck, Udo (London : International Society for Photogrammetry and Remote Sensing, 2004)
    Nowadays cartographic objects of different resolutions are hold in different coexisting databases. This implies an extensive amount of work for updating an object in all resolutions. One way to reduce this is to build a ...
  • Ziems, M.; Fujimura, H.; Heipke, Christian; Rottensteiner, Franz (London : International Society for Photogrammetry and Remote Sensing, 2010)
    This paper describes a semi-automatic system for road verification from high resolution orthophotos in an urban context. The system combines several road detection and road verification approaches from current literature ...
  • Mühr-Ebert, Elena L.; Wagner, Frank; Walther, Clemens (London : Elsevier Ltd., 2019)
    Environmental hazards are caused by uranium mining legacies and enhanced radioactivity in utilized groundwater and surface water resources. Knowledge of uranium speciation in these waters is essential for predicting ...
  • Yang, C.; Rottensteiner, F.; Heipke, C. (London : International Society for Photogrammetry and Remote Sensing, 2019)
    Land use and land cover are two important variables in remote sensing. Commonly, the information of land use is stored in geospatial databases. In order to update such databases, we present a new approach to determine the ...
