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
