GIS Maps for Disaster Management & Emergency Response
When an emergency or disaster hits, getting the right information of the situation is crucial to saving lives, accessing the damage to infastructure and finding the right resources to respond to the emergency or disaster. Geographic Information Systems (GIS) and satellite imaging technology has played a key role in retrieving data needed to assist emergency personnel to respond to various disasters and emergencies including, natural disasters and hazards, crime, defense and infastructure.

With larger scale emergencies and new threats to our country it is critical to prepare, prevent and recover from these casualties. Emergency personnel need to collaborate with many departments to plan effectively for responding to any emergency or disaster at hand. GIS maps integraded with satellite imagery provides information to access and analyze disasters of all types which assists emergency personnel to better prepare for potential threats and to allow responders to visualize the impact to communities and infastructure so recovery can begin.
