The Geospatial One-Stop (GOS) portal provides data that is shareable by anyone, anywhere. Overseen by the Office of Management and Budget (OMB), it is the result of an e-government initiative to make access to geospatial information from multiple sources faster and less expensive for all levels of government as well as the public. The site at www.geodata.gov was launched on June 30, 2003. The ESRI portal was chosen for the first-phase operational system based on usability and support factors. Experience ESRI garnered from developing similar international, federal, and state applications has gone into the design of GOS. Built with commercial off-the-shelf (COTS) software and based on open standards, the site is secure and supported 24/7 with fail-over capabilities. The portal was designed to be open and interoperable with virtually any GIS data set or service. In crafting GOS, ESRI paid attention to both Web services standards and emerging GIS standards from the Open GIS Consortium, Inc. (OGC), International Organization for Standardization (ISO), and the Federal Geographic Data Committee (FGDC). “This portal is a gateway to the National Spatial Data Infrastructure (NSDI) and the GIS superhighway,” said Jack Dangermond, ESRI president. “Not only does GOS simplify the search for data, it also centralizes access to services and lets users visualize map services across multiple servers, publish metadata and services, and learn about geospatial activities, standards, and other related information. This implementation was carefully designed to support publishing and access to geospatial knowledge of any type and from any vendor, regardless of format or standard.” “The portal’s aim is to make finding geospatial data easy and intuitive,” said Hank Garie, executive director for GOS at the United States Department of the Interior. Geodata.gov provides the tools necessary for greater intergovernmental collaboration and partnership on these key issues while reducing duplicative spending and wasted resources.
