Presentation Transcript
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


Initial goals
Initial Goals and Biological Oceanographic Data and Plans to Enhance It

  • 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.


Ultimate goal
Ultimate Goal and Biological Oceanographic Data and Plans to Enhance It

  • 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.


Us globec
US GLOBEC and Biological Oceanographic Data and Plans to Enhance It

  • Georges Bank

  • Southern Ocean

  • Gulf of Alaska

  • Northeast Pacific Program

  • Multi-national participation


Key data policy characteristics
Key Data Policy Characteristics and Biological Oceanographic Data and Plans to Enhance It

  • Dissemination to scientific investigators on a timely basis

  • Available when "useful"

  • Available to others outside the Program


Data and information
Data and Information and Biological Oceanographic Data and Plans to Enhance It

  • Field data

  • Retrospective studies

  • Laboratory experimental results

  • Modeling data

  • Information


Distributed
Distributed and Biological Oceanographic Data and Plans to Enhance It


Jgofs globec data management system
JGOFS/GLOBEC Data Management System and Biological Oceanographic Data and Plans to Enhance It

  • Distributed data servers

  • Web accessible

  • Supports plotting and downloading


Developed by flierl et al for us jgofs program
Developed by Flierl, et al. for US JGOFS Program and Biological Oceanographic Data and Plans to Enhance It

  • Distributed data - client/server system

  • Open access - read only

  • Quality control on-going

  • Emphasis on access to data and information as quickly as possible


Data acknowledgement policy
Data Acknowledgement Policy and Biological Oceanographic Data and Plans to Enhance It

  • 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.


Object server model
Object/Server Model and Biological Oceanographic Data and Plans to Enhance It

  • The data object receives requests and responds with data; and a server connects applications to objects.


Clients and servers
Clients and Servers and Biological Oceanographic Data and Plans to Enhance It

  • Browser application (Netscape, Internet Explorer, etc.)

  • Platform independent

  • More than just data served, information too

  • Based on "http" protocol


Centralized starting point
Centralized Starting Point and Biological Oceanographic Data and Plans to Enhance It

  • GLOBEC machine at WHOI

  • Directory shows data categories or hierarchy

  • Encourages use of common field names (thesaurus)


Example
Example and Biological Oceanographic Data and Plans to Enhance It

  • Start at home page

  • Go to data directory

  • Select data object

  • Data selection and projection options

  • Simple plots

  • Download options


Enhancements
Enhancements and Biological Oceanographic Data and Plans to Enhance It

  • Improve the visual interface to the data (map versus tabular)

  • Retain “data driven” attribute of system


Map tools
Map Tools and Biological Oceanographic Data and Plans to Enhance It

  • Live Access Server (LAS) – used by US JGOFS Program

  • MapServer

  • Generic Mapping Tools (GMT)

  • Digital Earth


Web based data access tools
Web Based Data Access Tools and Biological Oceanographic Data and Plans to Enhance It

  • WEBCOAST

  • GoMOOS

  • Joint Global Ocean Flux Study (JGOFS)

  • National Coastal Data Development Center (NCDDC)

  • The Federation GIS Services Cluster

  • Distributed Oceanographic Data System (DODS)

  • United Nations Environment Programme (UNEP)

  • Animated Earth (NASA)


Metadata and data access
Metadata and Data Access and Biological Oceanographic Data and Plans to Enhance It

  • 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


Learning about existing standards
Learning About Existing Standards and Biological Oceanographic Data and Plans to Enhance It

  • ECS, FGDC, GCMD common metadata

  • Mapping DIF to FGDC

  • Mapping DIF to Dublin Core

  • Guide to WMS


What s next
What’s Next and Biological Oceanographic Data and Plans to Enhance It

  • Implement metadata access via XML

  • Create WMS-based application to display data
