Knowledge of geography is critical to achieving comprehensive preparedness and response for homeland security. As GIS professionals, we must share with others how geography and GIS helps organizations with all aspects of protecting the homeland.

GIS analyzes the spatial relationships of assets, resources, and people, and is ideally suited to support many of the complex interrelationships of homeland security before, during, and after a crisis.

GIS helps detect and anticipate possible events, helps protect and defend people and assets, and assists in response and recovery efforts. GIS serves as a framework for data storage, data analysis, and visualization. This includes the locations of critical infrastructure, relationships with other important assets, and potential vulnerabilities. GIS can model potential incidents to help establish the most effective mitigation and protection strategies. GIS can also facilitate the exchange of spatial data across departmental sectors and various levels of government as part of the preparedness mission.

Emergencies, whether caused by nature or people, can strike without warning, and many emergencies affect multiple levels of government, multiple agencies, and private sector organizations. Therefore, homeland security, at every level, means having the people, procedures, and technology in place for secure data management with the flexibility to establish an effective, shared environment when needed. GIS provides homeland security personnel with the capabilities to meet these requirements.

Professionals in fire, law enforcement, emergency medical services, federal, state, and local government, and a myriad of other fields are working now to make a difference in defending our homeland. We’re thankful for all they’re doing. Feel free to share with us how you or someone you know is making a difference using GIS for homeland security. The more we can share, collaborate, and learn from one another, the more we can increase awareness about the power of GIS.
