GIS in Emergency Management
Roxanne GrayBob Busch
Wisconsin Emergency Management
June 3, 2010
GIS Valuable Tool in EM
Identify risk
Identify vulnerability to that risk
Assess the extent of the risk
Communicate the risk
Better land use decisions
Prepare for
Respond to
Recovery from
Mitigate (before, during or after an event)
Response/Recovery -
Damage Assessment
HAZUS (HAZards US –
Multi-Hazard)
Federal Emergency Management Agency (FEMA) disaster loss estimation and mitigation planning tool
Geographic Information System (GIS) based
Spatial Analysis tool required
Expensive to purchase and to maintain the licenses
Census Data
Methodology for Floods, Hurricanes, and Earthquakes
Physical damage
Economic Loss
Social Impacts
HAZUS -
Flood
Studies of discharge frequencies, including analysis of discharges from specific streams and the exposure to buildings and population from the resultant flooding.
Allows users to evaluate the consequences of specific actions, such as the introduction of flow regulation devices, acquisition or elevation of flood-prone properties, and other mitigation measures.
Wisconsin HAZUS-MH Risk Assessment
FFY 07 Pre-Disaster Mitigation Grant
Coordination with Land Information and Computer Graphics Facility (LICGF) at UW – Madison and The Polis Center at Indiana University – Purdue University at Indianapolis (IUPUI)
State wide riverine runs for all 72 counties and coastal runs for counties along Lake Superior and Lake Michigan
Uses Digital Elevation Maps (DEM)
DFIRMs where available
Better the data, better the ending product

Results were a 100-year flood analysis for each county
Data estimates are derived from census data incorporated into HAZUS

Mitigation Planning
Statewide flood hazard risk assessment for State Hazard Mitigation Plan
Flood analysis for each county
Assist in the development of or updating the counties’ all hazard mitigation plans

GIS in Radiological Emergency
Planning
GIS in Radiological Emergency Preparedness
Currently, only FEMA Region 5 has a GIS person devoted to Radiological Emergency Preparedness.
GIS in Radiological Emergency Preparedness
Only in the last 3 years has Wisconsin Emergency Management considered GIS as part of the skill set for employees.
4 staff with GIS skills
Uses of GIS in Radiological Emergency Management
Communicate Risk
Develop Plans to mitigate risk
Recovery – Post Event
Communicating Risk
GIS can be a powerful tool in the process of conveying risk.
Community Outreach
Planning Zones
Calendar
GIS in Risk Assessment and Planning
Provide the public with maps that show:
Areas that may be affected around the nuclear plant.
Roads
Evacuation Routes
A calendar is sent to each resident within 10 miles of the nuclear power plant.
State and County Plans
Reception Centers
Siren Locations
Traffic Control Access Points
Use of GIS in Exercises
To provide a visual aid in conveying technical data about a release.
Exercise Use Only
Parcels
Ingestion workshop
Ingestion Planning Zone extends 50 miles from the nuclear plant.
Discussions included using land parcels as a means to track individuals who did not evaluate.

Recovery
Why… There has not been an accident since Three Mile Island that has caused an evacuation.
Lessons could be taken from other incidents that require recovery, such as flooding.
