Visual Geophysical Exploration Environment VGEE ÜSimpler Visualization Environment ÜGuidance for Key Concepts ÜIsolate Processes Within Complex Systems
Java / GDV / Vis. AD ÜJava 1. 3 (application) ÄEasy exchange between VGEE components ÜUnderlying 3 D Viz. Environment ÄLeveraged from GDV and Vis. AD ÄGDV – 3 D Gridded Data Viewer (UNIDATA) ÄVis. AD – Java Visualization Component Library (SSEC / UNIDATA / NCSA / Aus. Bureau of Meteorology
Graphical User Interface (GUI) Main Display Visualization State 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 Ü Learner Friendly Ü Explore and Interact in 3 -D Ü Same tools as researchers, but set for survey level Viz: El Nino avg. DJF vertical wind speed cross-section and isosurface
Concept Models / Probes ÜConcept Models ÄStand-Alone ÄTeach basic principles in a user controlled environment ÜProbes ÄIsolate processes form the overall system ÄRelate learned concepts to the “real” world
Concept Models Ü Temperature Ü Condensation Ü Ocean Evaporation Ü Dry Adiabatic Ü Moist Adiabatic Ü Custom Moist Adiabatic Ü Ekman Wind Balance Ü Coriolis Force
Probes ÜSame as Concept Models ÜIntegrate with Dataset(s) Viz: Height (plan) Temperature (cross-section) with jet (isosurface)
