Merging Metadata Standards: FGDC CSDGM and ISO and Sharon Shin Federal Geographic Data Committee Metadata Coordinator

Why Create Metadata Allows agencies to: Organize and maintain the organization's data investment Share data set information through data catalogs and clearinghouses Provide access for download or display and analysis through web services

Metadata Allows users to: Discover, evaluate, and access geodata resources.

Consensus Standards Organizations ISO provides general purpose standards and specifications as guidance to implementation American National Standards Institute INCITS L-1: ANSI’s geospatial standards body FGDC- US Geospatial Metadata Standards body- Established standards with concensus from fed, Tribal, state, and local govts, academic

Why Standards? Interoperability- Allows communication between peers Minimizes data integration time … costs Permits data operations under known conditions

What’s Next: Crosswalk- Conversion Tool Content aligned with ISO Stand alone application Free, download from fgdc.gov

What’s Next: Metadata Profile Follow FGDC Standards Coordinator guidance for US National Profile review. Through collaboration with Canadian metadata develop content agreeable to both countries - arrive at North American Metadata Profile. Participation with Mexico’s metadata agencies under negotiation. If aggreement reached, US, Canada, Mexico North American Profile

What’s Next: FGDC Metadata Training Materials Develop FGDC CSDGM Version 3 workbook Develop base training materials and post to fgdc.gov Provide implementation assistance / training.
