  1. 3D Terrain and city models Eija Parmes VTT Eija.Parmes@vtt.fi

  2. 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

  3. State of art Terrasolid,FMKartta,HUT,FGI, Novosat Otaniemi model with aerial image giving texture.

  4. VirtualGlobeexplorers • 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

  6. 3D TerrainTEKES MASI Technology programe
