Geoportal Server: Open Source Software for Data Discovery and More

Time: 4:00-5:30

Location: Dupont Room

Convener: White, Casey, Relph, Neufeld, Parrish via the Web, Li

Key Topics

• ESRI GIS portal toolkit -> Geoportal Server ( Christine White (ESRI))
  • Highly configurable
  • Built on existing OSS platforms
  • Active development

• NODC use of Geoportal for Integration/Interoperation, John Relph, NODC, Ken Casey, NODC, Li, Jeff (NODC)
  • Archival work - human and machine interfaces
    • Target access to archives through various software services
    • Need for service integration and organization
  • Geoportal fills this need
  • Machine-to-machine communication via REST URL
    • Applications can construct individual URLs to pull targeted data
      • Metadata selections, but custom coding often needed for unique datasets
    • This lends itself to an agile archive which can conform to many different data/metadata requests
    • Dynamic, metadata created Web Accessible Folders (WAFs)
      • Brief Access Records merged with FGDC XML generates live archive WAF
• NODC Collections WAF
  • Collection level records, with HTML for Google harvesting
• Data.gov/Geospatial One-Stop WAFs
  • Immediately downloadable WAF only
• NODC Geoportal Server Usability Test for first-time users
  • Most use was scientific research
  • Many different countries
  • Spatial search had highest difficulty, free text and web interface tasks were also problematic
  • Indicated that the map locator needs work, as well as text search, default syntax, and ontology services were needed
  • Additional data visualization needed
  • Move for Geoportal to use ISO19115-2 metadata

• NGDC use of Geoportal David Neufeld (NGDC)
  • Mixed content, WAF centric
    • Common Property Meanings to create shared concepts
      • Simplifies search modifications, custom links to data
  • Improving metadata content
    • Must work with data providers
    • Metadata report card, based on metadata conventions
  • Federated searches
• Collaborations
  • Information sharing
  • GEO-IDE Wiki
  • Locator services
  • Google code shared repository possible

• EPA use of Geoportal David Parrish (EPA)
  • Environmental Dataset Gatewaty (EDG)
  • v 1.0 of Geoportal customized for EPA needs
  • Public demand drives division of Air, Water, Waste categories
  • Selection of data by region, type, owner
  • Code for searches available to be imbedded in third party webpages
  • Separation between public and private datasets
  • Automation of data.gov records/inventory/formatting
  • Metrics for data requests, world map of requests by country, metadata
  • Clip N Ship
  • Enhanced metrics, web services, web services and metadata
  • Outreach and sharing of tech
