Hierarchies of visualization needs in earth science with particular
applications to surface process and active tectonics investigations

Hierarchies
• 2D, 2.5D, 3D, 4D– Cartesian or not
Visualization Software• 2D: ArcMap, ArcIMS, GRASS,
GMT
• 2.5D: ArcScene, ArcGlobe, VRML
• 3D: VRML, OpenSceneGraph
• 4D: ArcScene fly (really 3.5D)?

Data requirements
• Digital Topography (including LiDAR)
• Remotely sensed imagery or shapefile texture map
• Seismicity, 3D structures, volume data
• Model inputs (geometry), outputs (calculated deformation fields) (e. g., Poly3D)

Integration requirements
• Democratization/portability
• Ease of adding content
• 3d interactivity: rapid zoom over large spatial scales of high res data (need LOD), as well as 3D digitizing and added surface fitting and other interpretive capability, including model steering.
