2007-12-15 AGU Presentation Web 2.0 2007-12-15 AGU Presentation Web 2.0 Presentation Transcript

  • Mashup of Tools through Interoperability Standards RSS, RDF, KML and XSL
    • E M Robinson , M Kieffer , S Kovacs , S R Falke , R B Husar
    • Washington University, St. Louis
    Fall AGU, Dec 13, 2007, San Fancisco
  • Emerging Air Quality Data Flow Network OGC WCS Data Access Protocol GEOSS Provides SOA for Coupling for Autonomous Nodes Facilitates Publishing, Finding and Accessing Data
  • Application of OGC WCS Data Access Protocol
    • Regardless of the data location, data type and format,
    • the parameter-space-time query is the same
    • the return is in user selectable format from the offerings
    Coverage=THEEDDS.T& BBOX=-126,24,-65,52,0,0 &TIME=2002-07-07/2002-07-07&FORMAT=NetCDF Coverage=SEAW.Refl& BBOX=-126,24,-65,52,0,0 &TIME=2002-07-07/2002-07-07&FORMAT=GeoTIFF Coverage=SURF.Bext& BBOX=-126,24,-65,52,0,0 &TIME=2002-07-07/2002-07-07&FORMAT=NetCDF-table Grid Image Station Data Parameter Bounding Box Time Range Out Format
  • Current SOA Air Quality Applications: Analysis Consoles
  • Web 1.0 -> Web 2.0 Transformation
    • The Web is being transformed: It is becoming more participatory
    • Its content is increasingly generated and distributed by individuals
    • See the explosive growth of wikies, picture-sharing, blogs, Facebook
    • This architectural, technological and cultural change is Web 2.0
    • Web 2.O is good for Earth Science community since it allows
      • Better harvesting of current knowledge
      • Collaborative creation new knowledge.
  • The Information Interoperability Stack
  • Community Data Sharing - ‘DataSpaces’ Catalog - Find Dataset Describe Dataset Discuss Dataset Earth Science Information Partners (ESIP)
    • Semantic Wiki: Structured (RDF and Unstructured Content
    • Open, Standard Matadata - RDF
    • Ready for Export/Harvesting by Registries, Catalogs
  • Communal Event Analysis Southern California Fire Smoke Approach (Blogs, Flickr, YOuTube): Use app to perform coarse filtering Controlled tagging in del.icio.us RSS feed from del.icio.us
  • May 07 Georgia/Florida Fires: Community-Supplied Observations Google and Technorati blog seaches yielded entries on GA Smoke. . Smoke images, were also found searching Flickr and Google Searching and pruning user-contributed Internet content yielded rich, but qualitative description of the May 07 Georgia Smoke Event. Videos of smoke were found on YouTube Visually pruned blogs, videos and images were bookmarked and tagged fore later analysis
  • Summary
    • The participatory web architecture and technologies are here
    • Standards are emerging for sharing previously unstructured data
    • The entry resistance to any particular Web 2.0 tool is rather low
    • However, many cultural, legal and other berries remain
    • The challenge is to learn how to apply these tools for Earth Science
