Geographic Support System Initiative

Overview
The U.S. Census Bureau's Geographic Support System Initiative (GSS-I)

"allows government agencies at all levels to regularly share and continuously update their address lists and road data with the Bureau. According to Bureau documents, GSS-I is relying on partnering with federal, state, tribal, and local government entities &mdash; as well as the private sector &mdash; to meet two Census-related data needs:


 * obtaining accurate, complete, and timely information about where people live (such as address data), coordinates of residential structures, and other map features (such as street centerlines), and
 * detecting information changes, so that the Bureau can identify such things as new roads and structures and update the MAF/TIGER database in response."
