What Role Does GIS Play During a Severe Weather
Event?

• All-Hazard Standardized Map
• Unified reporting tool used at the county level
• Created as a result of February 2007 flooding
• Can be accessed by the public from the IDHS
  homepage (www.in.gov/dhs)
• Updates to the map are done as needed depending
  the severity of the event and the status of each
  county

What Role Does GIS Play During a Severe Weather
Event?

• A FEMA program known as HAZUS MH can assist with
  model runs
• Specifically flooding for Indiana
• HAZUS is also used for earthquake scenarios
  (nationwide) and hurricanes along coastal areas
• The POLIS Center at IUPUI used NWS and USGS
  stream gauge data and flood reports to generate
  flood maps during January 2008 flooding

What Role Does GIS Play During a Severe Weather
Event?

• In January 2008 data was used to estimate the
  number of homes affected by flood waters as well
  as the extent to which the homes were flooded
• Models are still being refined, but the output
  gave a first guess as to the magnitude of the
  event
• Individual addresses with flood reports were
  generated by the model and placed in a GIS layer
• Flood depth reporting and river gauge data are
  critical for accurate model runs!

What Role Does GIS Play During a Severe Weather
Event?

• GIS also helps by allowing IDHS to map critical
  infrastructure in areas of concern to make our
  response more effective
• GIS allows us to see the big picture
• Physically seeing the data on a map can be very
  beneficial to the operational picture

What Does YOUR Help Do for IDHS?

• Eye-in-the-field reporting is critical for the
  most effective response from IDHS
• Information provided from the field helps drive
  the IDHS response and tells us where the most
  affected areas are
• Without important information from the field IDHS
  could not seek Federal disaster assistance
• It is VERY important to report what you see and
  know to your local authorities/EMA director
• The more info we have, the better the response we
  can provide!
