Topics

Overall, general topics of the SIG 3D Remote Sensing are as following:

• models for orientation/geo-referencing of single and multiple optical and radar images
• matching strategies for stereo and multiple imagery
• generation of Digital Surface Models (DSM’s) (the visible surface) based on space and aerial images, laser scanning, interferometric and radargrammetric Synthetic Aperture Radar (cooperation with the EARSeL SIG Radar Remote Sensing), with particular care to complex morphology areas (urban, mountain)
• generation of 3D-city models (cooperation with the EARSeL SIG Urban Remote Sensing)
• DSM and DEM comparison, cross-validation and quality assessment, with special attention for global DEM’s (as the new ASTER DEM)
• applications of DSM’s, DEM’s or other height information in engineering, land and environmental planning, management and protection
• determination of changes of the Earth surface
• 3D spatial databases
