The three-dimensional shape of the earth is of mayor importance for several remote sensing applications. It includes topics like digital elevation models as base of orthoimages or for the correct georeferencing, correct georeference independent upon the view direction and height, radiometric correction of images depending upon aspects, terrain analysis, flood prediction, coastal mapping, erosion control, determination of subsidence, noise and gas propagation, telecommunications planning and several other aspects. The digital elevation model can be generated based on existing topomaps or remote sensing data and can serve for the optimal use of other data.

TOPICS of Special Interest Group 3D Remote Sensing

  • determination of digital elevation models (DEM’s) based on space and aerial images, Interferometric Synthetik Aperture Radar (InSAR) and Laser scanning
  • comparison of DEM’s derived from existing topomaps and RS data
  • automatic generation of DEM’s from digital surface models (DSM’s) (the visible surface) by filtering
  • applications of DEM’s or other height information for remote sensing purposes
  • determination of changes of the earth surface
  • 3D spatial databases
