The GOS-PI National Spatial Data Infrastructure OGC OMB geospatial information Geospatial One-Stop Portal Initiative () aims to build a standards-based portal for discovery, access, and mapping. OGC is partnering with the Geospatial One-Stop project on this work. Led by the Department of the Interior, GOS is one of 24 US E-Government initiatives to improve effectiveness, efficiency, and customer service throughout all layers of government. Geospatial One-Stop builds upon objectives to enhance interoperability among geographic components of government activities. More information about Geospatial One-Stop is available at http://www.geo-one-stop.gov/. GOS-PI is part of OGC's Interoperability Program, a global, collaborative, hands-on engineering and testing program that rapidly delivers proven candidate specifications into OGC's Specification Program, where they are formalized for public release. In OGC's Interoperability Initiatives, international teams of technology providers work together to solve specific geoprocessing interoperability problems posed by the Initiative's sponsoring organizations. Questions about the Interoperability Program and GOS-PI should be addressed to Mr. Jeff Harrison, Executive Director, email@example.com, (703) 491-9543.
