Introduction
• In emergency situations, accurate, timely information is
critical
• Emergency responders need information delivered to
them on systems, and in formats that are easy to use,
understand, and interact with.
3
Key Concepts
• Design the end user application with mobility in mind
• Current online mapping applications (Google Maps, Bing
Maps, etc) are designed to dynamically adjust to the
viewing screen size
• Mobile GIS applications should leverage these services
and overlay situation specific information.
4
Possible data sources
• Commercial news sources
• Commercial imagery sources
• Social media outlets
• Local and National data sources
• Emergency responder on the scene
5
Data Processing/Management
• Computer Aided Dispatch
(CAD)
• Data gets routed
• Manage resources
• Relay communications
6
Unified Communications Center (UCC)
• Built in 2006, $116 million
• Brought together multiple
agencies
• Back-up facility
• 16 servers
• 150 workstations

Data analysis conceptual basis
• Automated data analysis
works for simple problems
• Manual data analysis
needed for complex
problems
• Specialty knowledge/
experience
• Mixed data format

Analysis framework and requirements
• Computer-assisted dispatch
• Analyze data and manage
response resources
• On-call subject matter
experts
• Expert teams model
• HHS Emergency
Command Center
• CAD-to-CAD exchange

Scenario 1—chemical spill
• A tanker truck crashes and
liquid chlorine spills…
• …outside the Capital
• …entering a tunnel
• …near a Metrorail
• Instead of chlorine, the
spilled liquid is…
• …hydrogen cyanide
• …nitrogen

Scenario 2—run on over-the-counter medicine
• OTC cough syrup sales
peak in December…
• …nationwide
• …at all DC pharmacies
• …at select pharmacies
• Instead of December, the
peak is in July
• Instead of cough syrup, the
medicine is an antifungal
