Visualization and workflows
Gregory Leptoukh & Christopher LynnesNASA GSFC
Topics• Package vs. API • Using just a visualization part• The more powerful, the less control - need to find
middle ground• Adjusting look publication quality?• Google API not suitable for science?• Use inside workflow• Visualization vs. WMS (+provenance)• REST protocol for visualization• 3D interactive vs. performance

Giovanni Allows Scientists to Concentrate on the Science
GES DISC tools allow scientists to compress the
time needed for pre-science preliminary tasks:
data discovery, access, manipulation, visualization,
and basic statistical analysis.
