Why 3D Navigation?

  • The terrain shape is a source of information in itself!
  • Habitat and landscape boundaries have simpler connotations
  • Interactive exploration of a 3D model allows users to discover features not easily detectable using traditional 2D cartographic representations
  • 2D operation (pan/zoom) can be obtained naturally in 3D by constraining the camera motion

    • 3D terrain
