Academic Applications of GIS GIS in Emergency Management and Homeland Security
Applications of GIS in an academic environment Resources – curriculum, user groups and more Conclusions Goals
Contributes to each facet of faculty professional development Academic Applications of GIS
Teaching Course projects, labs, data Technology, Emergency Management, GIS, Economics, Engineering, Science, Geography, Remote Sensing Research Grants Multidisciplinary Mitigation and Preparedness Service Collaboration with public/private sectors Federal, State, Local, community projects Academic Applications of GIS
Graduate or Undergraduate level applications General Education courses Examples Emergency Management – risk assessment, hazard profile, social vulnerability, critical infrastructure, lifelines, emergency response Geography – mapping applications for emergency planning, demographics, physical geography Planning – zoning, building ordinances, land use Engineering – modeling, basic engineering applications Earth Sciences – geology, meteorology Can we think of others? Teaching
California University of Pennsylvania B.A. Geography concentration in GIS & Emergency Management Demographic Analysis Climatology Impacts and Sustainability of Tourism Developing the Master Plan Geographic Information Systems GIS 2 Crime Mapping & Spatial Analysis Natural Hazards Emergency Management Disaster Vulnerability Assessment Teaching
Multidisciplinary collaborations Private/Public sector and university collaborations Scenarios, Loss estimates, Models, Economics, Engineering Data Flood Model Hurricane/Wind Model Earthquake Model Internships – valuable experience for students Research
Facilitates a risk-based approach to mitigation Calculates scientifically-defensible damages, economic losses, and mitigation benefits Identifies and visually displays hazards and vulnerabilities Free ArcGIS 9 extension What is HAZUS?
HAZUS-MH allows user to IDENTIFY vulnerable areas ASSESS level of readiness and preparedness to deal with a disaster before disaster occurs ESTIMATE potential losses from specific hazard events DECIDE on how to allocate resources for most effective and efficient response and recovery PRIORITIZE mitigation measures that need to be implemented to reduce future losses (what if) What is HAZUS?
Inventory is divided into two categories Common to all hazards General building types and occupancies Lifelines Replacement costs Demographics Hazard-specific Specific building types Elevation Building configurations What is HAZUS?
User Levels Input hazard specific data Level 3 Required User Effort and Sophistication Combinations of local and default hazard, building, and damage data Level 2 Default hazard, inventory, and damage information Level 1
Supported Hazards Hurricanes Riverine and Coastal Floods Earthquakes
Over 4,200 users in 2004 – 19,600 users predicted by 2008 International users – Norway, Turkey, and Sweden pilot programs Who Uses HAZUS?
HAZUS Overview HAZUSLibrary Model Details User Group Information Training Other Resources www.fema.gov/plan/prevent/hazus/index.shtm
Assess damage and losses based on hazard conditions Example – Hurricane model has 1884 unique building categories 45 damage/loss functions for each building model ~85,000 unique damage/loss curves Damage/Loss Functions
Model includes 22 gulf and east coast states as well as Hawaii Supported States
