Two Degrees To SensoWeb

  1. 1. Two-Degrees To SensorWeb Pat Cappelaere, Vightel Corporation Stu Frye, SGT Dan Mandl, NASA GSFC CTS 2009, Baltimore -- May 18-22,2009
  2. 2. Title Clue The trivia game Six Degrees of Kevin Bacon is based on the concept of the small world phenomenon and rests on the assumption that any actor can be linked through his or her film roles to actor Kevin Bacon Every Actor has a Bacon Number!
  3. 3. Every Scientist has an Erdös Number Scientists and mathematicians have been calculating their Erdös number for years. Paul Erdös was the Kevin Bacon of mathematicians, having published more than 1400 papers with numerous collaborators. Anyone who was a co- author with Erdös has an Erdös number of one. Their collaborators, in turn, have an Erdös number of two, and so on. The network of mathematicians is a small-world network.
  4. 4. 6.6 quot;Worldwide Buzz: Planetary-Scale Views on an Instant- Messaging Network,quot; Eric Horvitz of Microsoft Research and Jure Leskovec of Carnegie Mellon University analyzed 30 billion conversations among 240 million people using Microsoft Instant Messenger in June 2006
  5. 5. ✓ California Fires ✓ Myanmar Cyclone ✓ Zambezi Flood... SensorWeb Support Humanitarian Assistance and Disaster Relief Efforts Provide End-Users Customized Data They Can Use To Make Decisions In the Field A NASA ESTO Technology Project With OGC Standards 5
  6. 6. Droughts Hurricanes Fires Floods
  7. 7. Technology OGC Standards - SPS, SOS, WPS, WFS, WMS, WCS... Automated Workflows - WfCS, Wf-XML... Data Dissemination - GeoRSS Product Feeds, GeoTorrents Data Visualization - Google Earth, WorldWind... Notifications - Twitter, SMS, GeoActivity Streams... Scalable Architecture - Resource Oriented Architecture (Not SOAP/WSDL)
  8. 8. Collaboration Who Are Your Users? Which Are The Legitimate Application Consumers and Service Providers? Are We or Can We Be Sharing The Data With You? Can We Do Secure Transactions?
