NOAA Ocean Service Enterprise GIS for NOAA’s Ocean Service NOAA’s Ocean Service Data Distribution Variety of coastal and ocean data created by Ocean Service Many web sites and a variety of data delivery approaches

NOAA Ocean Service Enterprise GIS for NOAA’s Ocean Service Observations of NOS Sites… 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 Sheer number of discovery and delivery mechanisms makes data accessibility difficult and time consuming – limiting overall user base and satisfaction

NOAA Ocean Service Enterprise GIS for NOAA’s Ocean Service 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)

NOAA Ocean Service Enterprise GIS for NOAA’s Ocean Service 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

NOAA Ocean Service Enterprise GIS for NOAA’s Ocean Service 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

NOAA Ocean Service Enterprise GIS for NOAA’s Ocean Service What’s next for NOS DataExplorer? Integrated with GeoSpatial One-Stop (GOS) – NOS Data holdings channel for GeoSpatial One-Stop International Ocean Observing System (IOOS) – Providing base-map layers for over-rendering of observational data – Integration of observations data sources as viewable/downloadable datasets for DataExplorer users Gulf of Maine, Ocean Observing System (GoMOOS) – NOS Data Explorer will participate as a data provider, using WMS map services, to provide a base data for the Gulf of Maine Framework Data Project.
