  2. New technologies can promote public visualization of NOAA’s data assets • 1) Virtual globe software (and Google Earth in particular) is steadily capturing the imagination of the public, as a natural interface for geospatial data. • 2) A steadily increasing catalogue of NOAA’s oceanographic and atmospheric data is available through OPeNDAP technology. • 3) Low-cost immersive technology (e.g. the GeoWall) has proven its value in public education and scientific analysis, for the display of geospatial data.

  3. Google Earth • GE is a free geospatial viewer with the popular appeal of a videogame experience • GE has a simple scripting language: KML (keyhole markup language)http://www.keyhole.com/kml/kml_tut.html • A free stereo viewer for GE is now available: http://www.tridef.com/promotions/google-earth.html

  4. Google Earth topography in stereo

  5. We use model output to demonstrate oceanic capabilities

  6. Accomplishments thus far • Rendered simple objects in GE: • 2D plots • Animated translucent 3D “fog” • Animated 3D float tracks with bathymetry • Utilized an openDAP server (DAPPER) to render isosurfaces in GE • Assembled a portable geowall for immersive stereo rendering • Demonstrated the system to a large audience

  7. Simple 2-D plot in GE using gif transparency

  8. Stacked translucent gifs create 3D“fog” • GE presently has no ocean depth so must build 3D worlds in to the sky….

  9. 3D fog: results from CGOA modeling • Temperature of the top 100m of the ocean • Jun 03- Jun 08 of 2001 • Red is hotter, Blue is colder • Here, look directly down from above, through the fog

  16. Sample 3D float track with crude bathymetry surface

  17. DAPPER server for display of surfaces in GE • Interactive selection of region, time, isosurface • Demo version hosts Eco-FOCI model output • Generates kml file which is displayed by GE • Uses COLLADA language for compact representation of surfaces

  18. Salinity isosurface (red) with bathymetry (blue)

  19. Visualize in stereo!

  20. Same surfaces from a different angle

  21. Equipment for portable stereo system • Laptop with dual video output • Small projectors (each ~size of a submarine sandwich) • Medium-sized screen, easy to carry • Polarized glasses

  22. A portable geowall in use… • Projectors are small!

  23. Issues for future work • We anticipate GE will add ocean bathymetry • This would allow a true 3D ocean in the ocean • GE has high potential for interactive display from many sources • Live Access Server has interactive refresh during navigation in GE • Simultaneously compare model output with data from multiple servers
