NOAAs Ocean Service Data Distribution

• Variety of coastal and ocean data created by
  Ocean Service
• Many web sites and a variety of data delivery
  approaches

3
Problem

• Users must navigate multiple sites to find data
• 13 different sites for the primary NOS datasets
• Variety of mechanisms for just getting the data
• FTP/HTTP, various IMS, off-the-shelf custom
  tools, etc
• Multiple data viewer types and styles
• ArcIMS, MapObjects, Minn. MapServer and others
• No interface for previewing data coverage of NOS
  data holdings from all Program Offices at once
• Complexity of discovery and delivery mechanisms
  makes data accessibility difficult and time
  consuming
• limiting overall user base and satisfaction

4
The idea

• Goal
• Develop a single point of entry for GIS data
  discovery and delivery
• Objective
• Increase the diversity and number of uses and
  users of our spatial data holdings
• Requirements
• Data remains distributed with originator
• Standards-based approach FGDC Metadata and open
  standards and protocols (OGC, W3C)

Enterprise GIS Framework Tools

• Commercial Off-the-Shelf Software
• ESRI ArcIMS 4.0.1 - Map image and data stream
  construction
• Out-of-the-box ArcIMS template, customized for
  look-n-feel
• Out-of-the-box ArcIMS Metadata Explorer
• ESRI ArcSDE Spatial reference inventory
• Local footprint outlines of the remote data
• Always searchable, even when remote servers down
• Microsoft SQL Server
• Request registry and remote data source
  connectivity knowledge
• Microsoft IIS
• ServletExec JavaVM ISAPI container
• Java 2 (Enterprise Edition)
• JSP/JSTL/JDBC Web-UI construction, system flow
  control, error handling and data source
  connectivity

Networking considerations

• NOS CIOs office aided in the development of a
  multi-tier architecture to support the NOS
  DataExplorer
• Leveraged existing resources provided by the NOS
  CIOs office
• Secure Public Information Network (SPIN)
• Provides a single tier of security between the
  system and the public as well as between the
  system and internal resources.
• 24x7 managed server-tier for DataExplorer
• Server load balancing and cluster management
  support
• Database Administration support
• System-level utility development
• On-demand server-side troubleshooting/support

Download Process

• Request processing job fires every few hours
• Iteration through pending requests
• Individual layers in the request bundle extracted
  by extent and/or feature-by-feature
• Downloads inventory/footprint and all remote data
  for each feature in the user defined extent
• Downloads the FGDC Metadata for
  inventory/footprint as well as for each feature
  (if supported by data provider)
• Packages (zips) up the files moves to the FTP
  site
• Notifies the user to come collect their package

10
NOS DataExplorer

• Single point of data discovery and delivery while
  maintaining distributed data
• Utilizing open standards OGC WMS, ESRI ArcXML,
  W3C XML HTTP, ISO TCP/IP
• Integrated NOS data coverage visualization
  on-the-fly over the web
• Compatible with both ESRI as well as
  OGC-compliant products client tools
• 24x7 availability
• Support provided by the NOS CIO

Whats next for NOS DataExplorer?

• Moving on Version 2 Enhancements
• - Interface and Search functionality
• - Adding additional datasets
• Operational Product (Rick Spinrad)
• - Requirements
• Integration with Larger Efforts
• - Geospatial One Stop (GOS)
• - International Ocean Observing System (IOOS)
• - Gulf of Maine, Ocean Observing System
  (GoMOOS)
