  1. Center of Higher Learning High Performance Visualization Center Buoy Data Visualization Denise Runnels Supreeya Miller Sharif Khalid

  2. Goals • Visual Representation of Buoy Data • Prototype for NDBC

  3. Topics of Discussion • NDBC portrayal of data • Hardware and software tools used • Our portrayal of data

  4. National Data Buoy Center • NDBC is part of the National Weather Service (NWS) • “Develops, operates and maintains a network of buoy and coastal-marine automated network (C-MAN) stations” that NWS uses in preparing forecasts

  5. NDBC Data Collected: • Air temperature • Sea surface temperature • Wave direction, heights and periods • Wind speed, direction, and gust • Barometric pressure • Station visibility • Date and time

  6. Raw Buoy Data • So far this data is represented as a collection of numbers and static strip charts.

  7. Visualize Buoy Data • We can combine computer graphical tools with the buoy data to make a real time moving image that has more innate meaning than the raw data alone.

  8. Hardware Tools • SGI Onyx2 • Linux workstations

  9. Software Tools • C and C++ • OpenGL • OpenGL is an open visualization software package • Compatible with several different machine platforms and is therefore relatively portable • Text Font library

  10. Raw Buoy Data These tools combined with this data becomes …

  11. Air and Sea Surface Temperature

  12. Wave Data Representation

  13. Wave Height

  14. Wind Speed & Direction

  15. Gust Speed & Direction

  16. Mouse Clicks

  17. Future Plans • We are working on several interactive options for the user such as: • Varying the speed (Human factor engineering) • Different day and night effects • Choice of which buoy station the data comes from by clicking on a map
