Background
• Increasing need for realistic 3D terrain
and city models : planning, simulation,
maintenance , security, games,
navigation
• Also as user interface to spatial data
and activities (front page in Search
engines ?)
• Methods exist for the creation of 3D
models: laser scanning,
photogrammetry, image analysis

Development needs
• More automatic mapping of buildings and trees
• Up to date information on land cover and
vegetation
• Genuine 3D modelling of geospatial objects and
massive 3D data
• Consistent 3D geospatial referencing of the objects
• Real time navigation technology in large area
detailed models
