Visual Geophysical Exploration Environment
VGEE
Simpler Visualization Environment
Guidance for Key Concepts
Isolate Processes Within Complex Systems
Java / GDV / VisAD
Java 1.3 (application)
Easy exchange between VGEE components
Underlying 3D Viz. Environment
Leveraged from GDV and VisAD
GDV – 3D Gridded Data Viewer (UNIDATA)
VisAD – Java Visualization Component Library (SSEC
/ UNIDATA / NCSA / Aus. Bureau of Meteorology
Graphical User Interface (GUI)
Visualization
State
Main Display
Track/update/change
parameters
Displays
visualization
information
Launch new viz tools
Interactive
Versatile
Uses canned and
user supplied
datasets
Probe Window
Displays specific isolated information from the
overall visualization
VGEE GUI
Learner Friendly
Explore and Interact
in 3-D
Same tools as
researchers, but set
for survey level
Viz: El Nino avg. DJF vertical wind speed cross-section and isosurface
Concept Models / Probes
Concept Models
Stand-Alone
Teach basic principles in a user controlled
environment
Probes
Isolate processes form the overall system
Relate learned concepts to the “real” world
Concept Models
Temperature
Condensation
Ocean Evaporation
Dry Adiabatic
Moist Adiabatic
Custom Moist Adiabatic
Ekman Wind Balance
Coriolis Force
Probes
Same as
Concept Models
Integrate with
Dataset(s)
Viz: Height (plan) Temperature (cross-section) with jet (isosurface)
