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)?



Hierarchies

(Thin) client, Desktop, Geowall, BigWall, Cave

for/within/enabling an Earth Science Interpretive Environment

Bernadin, et al., Real-time Terrain Mapping, IEEE Transactions on Visualization and Computer Graphics, 2005


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)


Visualizing model mechanical models

Faults in N. Sea oil reservoirPoly3D: http://pangea.stanford.edu/research/geomech/


Stresses in N. Sea oil reservoirPoly3D: http://pangea.stanford.edu/research/geomech/


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.
