The Department of Homeland Security (DHS) recently released a document meant to serve as an executive level briefing on the 16 sectors of infrastructure that have been designated as critical by the Department. The 52-page guide provides a brief overview of each sector, and then offers "Threats and Hazards of Concern" for that sector. Find it at the link below:

Comment: Kudos to DHS - this is a well done document with one exception. Missing from consideration is the infrastructure that brings meaning to ALL other infrastructure. That would be the nation's geospatial infrastructure. Please see the National Spatial Data Infrastructure and GITA's GECCo program to understand the point.
