  • Analysis of UAV-acquired wetland orthomosaics using GIS, computer vision, computational topology and deep learning 
    Kentsch, Sarah; Cabezas, Mariano; Tomhave, Luca; Groß, Jens; Burkhard, Benjamin; Caceres, Maximo Larry Lopez; Waki, Katsushi; Diez, Yago (Basel : MDPI AG, 2021)
    Invasive blueberry species endanger the sensitive environment of wetlands and protection laws call for management measures. Therefore, methods are needed to identify blueberry bushes, locate them, and characterise their ...
  • Assigning tie points to a generalised building model for UAS image orientation 
    Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2017)
    This paper addresses the integration of a building model into the pose estimation of image sequences. Images are captured by an Unmanned Aerial System (UAS) equipped with a camera flying in between buildings. Two approaches ...
  • High-resolution signal-in-space measurements of VHF omnidirectional ranges using UAS 
    Schrader, Thorsten; Bredemeyer, Jochen; Mihalachi, Marius; Ulm, David; Kleine-Ostmann, Thomas; Stupperich, Christoph; Sandmann, Sergei; Garbe, Heyno (Göttingen : Copernicus GmbH, 2019)
    In this paper, we describe measurement results of the signal-in-space of very high frequency (VHF) omnidirectional range (VOR) facilities. In aviation VOR are used to display the current course of the aircraft in the ...
  • Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)-the Hailuoto 2017 campaign 
    Kral, Stephan T.; Reuder, Joachim; Vihma, Timo; Suomi, Irene; O'Connor, Ewan; Kouznetsov, Rostislav; Wrenger, Burkhard; Rautenberg, Alexander; Urbancic, Gabin; Jonassen, Marius O.; Båserud, Line; Maronga, Björn; Mayer, Stephanie; Lorenz, Torge; Holtslag, Albert A.M.; Steeneveld, Gert-Jan; Seidl, Andrew; Müller, Martin; Lindenberg, Christian; Langohr, Carsten; Voss, Hendrik; Bange, Jens; Hundhausen, Marie; Hilsheimer, Philipp; Schygulla, Markus (Basel : MDPI AG, 2018)
    The aim of the research project "Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)" is to substantially increase the understanding of the stable atmospheric boundary layer (SBL) through ...
  • Integration of a generalised building model into the pose estimation of UAS images 
    Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    A hybrid bundle adjustment is presented that allows for the integration of a generalised building model into the pose estimation of image sequences. These images are captured by an Unmanned Aerial System (UAS) equipped ...
  • 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 ...
  • A new approach for an incremental orientation of micro-UAV image sequences 
    Reich, Martin; Unger, Jakob; Rottensteiner, Franz; Heipke, Christian (Göttingen : Copernicus GmbH, 2014)
    Civil applications for small size unmanned aerial vehicles (UAV) have become quite important in recent years and so have accurate orientation and navigation of these devices in unknown terrain. In this work we focus on ...
  • On the Discrepancy in Simultaneous Observations of the Structure Parameter of Temperature Using Scintillometers and Unmanned Aircraft 
    Braam, Miranda; Beyrich, Frank; Bange, Jens; Platis, Andreas; Martin, Sabrina; Maronga, Björn; Moene, Arnold F. (Dordrecht : Springer Netherlands, 2016)
    We elaborate on the preliminary results presented in Beyrich et al. (in Boundary-Layer Meteorol 144:83–112, 2012), who compared the structure parameter of temperature (C2T) obtained with the unmanned meteorological mini ...
  • Review of remote sensing for land administration: Origins, debates, and selected cases 
    Bennett, Rohan Marc; Koeva, Mila; Asiama, Kwebana (Basel : MDPI AG, 2021)
    Conventionally, land administration—incorporating cadastres and land registration—uses ground-based survey methods. This approach can be traced over millennia. The application of photogrammetry and remote sensing is ...
  • Thermal IR imaging: Image quality and orthophoto generation 
    Sledz, A.; Unger, J.; Heipke, C. (Göttingen : Copernicus GmbH, 2018)
    This paper deals with two aspects of photogrammetric processing of thermal images: image quality and 3D reconstruction quality. The first aspect of the paper relates to the influence of day light on Thermal InfraRed (TIR) ...
  • UAV-based photogrammetry: Monitoring of a building zone 
    Unger, Jakob; Reich, Martin; Heipke, Christian (Göttingen : Copernicus GmbH, 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 ...
