Ocean Surface Current Visualization-worldwide

Click For Summary
SUMMARY

The forum discussion focuses on a visualization of ocean surface currents worldwide, covering the period from June 2005 to December 2007. The visualization, available at NASA's SVS website, aims to provide a visceral experience without narration or annotations. Users express a desire for an interactive version similar to Google Earth, suggesting that the data could be stored efficiently using vectors for coordinates, potentially reducing file sizes significantly compared to the current downloadable versions.

PREREQUISITES
  • Understanding of oceanographic data visualization techniques
  • Familiarity with vector data storage methods
  • Knowledge of geographic coordinate systems (latitude and longitude)
  • Experience with large data file management and optimization
NEXT STEPS
  • Explore the capabilities of Google Earth for interactive data visualization
  • Research efficient data compression techniques for large datasets
  • Learn about oceanographic data collection methods and their implications
  • Investigate tools for creating interactive visualizations from raw data
USEFUL FOR

Oceanographers, data visualization specialists, software developers interested in geographic information systems, and anyone involved in environmental data analysis.

This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.

(beware, the downloadable visualization files are HUGE)

Nice thing.

I would love to be able to watch it as in Google Earth, selecting places I am interested in.

Actually I wonder if such a program would be not even smaller than the movie I just downloaded. Most of the displayed information is an extrapolation, so perhaps it is enough to remember a vector for just every whole coordinate (degs, latt & long) - and that can be stored with a reasonable accuracy in just two bytes, so 128 kB per whole map (land included), and I doubt they have data better than one measurement per day. That gives around 47 MB per year - minus 25% for lands, but perhaps more dense grid from better known areas. Still, even at 100 MB per year that's far from several GB.
