Emergency Services Sector
Department of Homeland Security

The Emergency Services Sector (ESS) represents the nation’s first line of defense in the mitigation and prevention of risk from both intentional and unintentional manmade incidents, as well as from natural disasters. The Emergency Services Sector-Specific Plan details how the National Infrastructure Protection Plan risk management framework is implemented.

Mission Support

The Emergency Services Sector works in close collaboration with its stakeholders’ day-to-day operations, facilities and organizations. The SSA lead coordinates with each of the disciplines to ensure that any outstanding requirements are met. Much of the stakeholders’ geospatial needs are met with their internal and EOC resources, providing relevant information to and through the SSA lead. Additional requirements for geospatial products are coordinated through the NICC by the SSA.


The bulk of the geospatial products available within the Emergency Services Sector are developed at the local level with minimal products and data produced and/or available through the SSA. In most situations, the entities manage their efforts internally, providing internal reports and data to the SSA lead.
