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

Virtual Globe explorers

• Google Earth, Sintef Virtual Globe, World Wind

5
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
