Integrating NOAA’s Unified Access Framework in GEOSS: Making Earth Observation data easier to access and use Matt Austin NOAA Technology Planning and Integration for Observations Office Erth

Aligning NOAA’s mission with GEOSS Promoting Global Environmental Stewardship – Describing assessing, monitoring and predicting the Earth’s environment – Weather, Climate, Ocean, Coasts, Satellites Management of data information services – Acquisition, archive, access, integration and dissemination of environmental data

What is the Unified Access Framework? NOAA-wide effort to make complex environmental datasets easier to find and use Many of NOAA datasets that have been derived from Ocean Models, Climate, Weather, Satellites, HF Radar have not been easily accessible to broader user communities in the past Provides data access using open standards

UAF interoperability domains and data management functions

NOAA’s Unified Access Framework Unique access point to federated data services for NOAA Priority Earth Observation Data A standards based architecture – Data Format and dataset vocabulary: NetCDF-CF – Catalog: THREDDS – Data Access Protocol :Opendap, WCS, WMS – Metadata: ISO User friendly tools to access data that are web and desktop based

NOAA UAF Project Integration Issues and Challenges: UAF is a volunteer effort which makes it hard to achieve goals on a set schedule UAF THREDDS catalog contains sparse inconsistent metadata ncISO generated metadata does not include links to access data….yet (coming soon) Defining granularity for data and metadata Many NOAA datasets need to be integrated

GEOSS Interoperability Challenges Registering data and services in the GCI is a manual data entry driven process GEOSS tasks that are interdependent such as Ontology, AIP and GCI development need to be better coordinated GEOSS Clearinghouse needs to be kept current – Old metadata – GEOSS standards not updated frequently

How better metadata can simplify integrating data into GEOSS The relationship between data, services, products and clients can be described using metadata Publishing this metadata in a Web Accessible Folder recognized by the GCI could automate the registration process for data and services resulting improved usability for GEOSS providers and users
