Presentation Transcript


Initial goals

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

  • 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

  • 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

  • Georges Bank

  • Southern Ocean

  • Gulf of Alaska

  • Northeast Pacific Program

  • Multi-national participation


Key data policy characteristics

Key Data Policy Characteristics

  • Dissemination to scientific investigators on a timely basis

  • Available when "useful"

  • Available to others outside the Program


Data and information

Data and Information

  • Field data

  • Retrospective studies

  • Laboratory experimental results

  • Modeling data

  • Information


Distributed

Distributed


Jgofs globec data management system

JGOFS/GLOBEC Data Management System

  • 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

  • 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

  • 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

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


Clients and servers

Clients and Servers

  • 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

  • GLOBEC machine at WHOI

  • Directory shows data categories or hierarchy

  • Encourages use of common field names (thesaurus)


Example

Example

  • Start at home page

  • Go to data directory

  • Select data object

  • Data selection and projection options

  • Simple plots

  • Download options


Enhancements

Enhancements

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

  • Retain “data driven” attribute of system


Map tools

Map Tools

  • 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

  • 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)


Metadata and data access

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


Learning about existing standards

Learning About Existing Standards

  • ECS, FGDC, GCMD common metadata

  • Mapping DIF to FGDC

  • Mapping DIF to Dublin Core

  • Guide to WMS


What s next

What’s Next

  • Implement metadata access via XML

  • Create WMS-based application to display data
