What I’m Going to Cover

NSDI Evolving

GOS Portal Enhancements

Example New ‘Service’ - Integration with GOS

How should we measure Agency Participation in GOS?

Evolving Spatial Data Infrastructures

Application focus IT standards Interoperable

GIS Portals

Clearinghouses

System-oriented Data focus Geo-standards Top down

File Transfer Ad hoc Data focus FTP transfer Bottom up
