Presentation Transcript

  1. The JGOFS/GLOBEC Data Management System for Serving Physical and Biological Oceanographic Data and Plans to Enhance It • Presented at the Open Geospatial Consortium Technical Committee Meeting – Natural Resources and Environment Working Group • R.C. Groman, P.H. Wiebe, N.H. Vine • and M.D. Allison • 18 January 2005

  2. Initial Goals • To understand the population dynamics of key species in terms of their coupling to the physical environment and in terms of their predators and prey.

  3. Ultimate Goal • To be able to predict changes in the distribution and abundance of target species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.

  4. US GLOBEC • Georges Bank • Southern Ocean • Gulf of Alaska • Northeast Pacific Program • Multi-national participation

  5. Key Data Policy Characteristics • Dissemination to scientific investigators on a timely basis • Available when "useful" • Available to others outside the Program

  6. Data and Information • Field data • Retrospective studies • Laboratory experimental results • Modeling data • Information

  7. Distributed

  8. JGOFS/GLOBEC Data Management System • Distributed data servers • Web accessible • Supports plotting and downloading

  9. Developed by Flierl, et al. for US JGOFS Program • Distributed data - client/server system • Open access - read only • Quality control on-going • Emphasis on access to data and information as quickly as possible

  10. Data Acknowledgement Policy • Data sets being collected are most worthwhile in the context of all the other data sets being collected • Investigators must respect the ownership of the data and should request permission to use data. Collaboration encouraged.

  11. Object/Server Model • The data object receives requests and responds with data; and a server connects applications to objects.

  12. Clients and Servers • Browser application (Netscape, Internet Explorer, etc.) • Platform independent • More than just data served, information too • Based on "http" protocol

  13. Centralized Starting Point • GLOBEC machine at WHOI • Directory shows data categories or hierarchy • Encourages use of common field names (thesaurus)

  14. Example • Start at home page • Go to data directory • Select data object • Data selection and projection options • Simple plots • Download options

  15. Enhancements • Improve the visual interface to the data (map versus tabular) • Retain “data driven” attribute of system

  16. Map Tools • Live Access Server (LAS) – used by US JGOFS Program • MapServer • Generic Mapping Tools (GMT) • Digital Earth

  17. Web Based Data Access Tools • WEBCOAST • GoMOOS • Joint Global Ocean Flux Study (JGOFS) • National Coastal Data Development Center (NCDDC) • The Federation GIS Services Cluster • Distributed Oceanographic Data System (DODS) • PO.DAAC Ocean ESIP Tool (POET) • Comprehensive Large Array-data Stewardship System (CLASS) • EarthRef.org • SIOExplorer • Federal Geographic Data Committee (FGDC) • Australian Spatial Data Directory (ASDD) • United Nations Environment Programme (UNEP) • Animated Earth (NASA)

  18. Metadata and Data Access • Metadata currently presented as text via the web. Current plan is to convert to XML • Data access is via wget application or JGOFS/GLOBEC list application

  19. Learning About Existing Standards • ECS, FGDC, GCMD common metadata • Mapping DIF to FGDC • Mapping DIF to Dublin Core • Guide to WMS

  20. What’s Next • Implement metadata access via XML • Create WMS-based application to display data

  21. Questions, Comments and Suggestions
