|| The DHS Spatial Data Infrastructure (SDI), a subset of the Enterprise Architecture, consists of geographic information systems software and hardware, geospatial applications, data, standards, policies, programs, and the human resources necessary to acquire, process, analyze, store, maintain, distribute, and otherwise use geospatial data as a strategic asset for the Department of Homeland Security . . . and the nation. The basis for an SDI is to identify and organize core capabilities that have common applications and to ensure the transport of data, via compatible formatting, across DHS. Completing and maintaining an SDI with integrated applications and systems will provide the level of geospatial preparedness required to protect the nation's critical infrastructure, strategic assets, the economic base, and America's citizens.
