NSDI Evolving
GOS Portal Enhancements
Example New ‘Service’ - Integration with GOS
How should we measure Agency Participation in GOS?

Some Lessons Learned
Metadata is difficult Difficult to publish Difficult to be consumed by end users
Not all data is available to users Not all data is registered Searching data is not easy Too many steps to contribute content
Result GIS Portals aren’t reaching their full potential

Measuring Agency Participation
How should we measure participation? Encourage progress? Proposed –
Q2 and Q4 OMB EGov Milestones Published our new metadata Published our new data plans Reviewed and updated our A-16 Data Communities
(Links Working) Registered Map Services and Applications?
Supporting data from the portal (standard form?) FGDC Annual report used to discuss other
participation – establishing web services etc…
