What is a DFIRM ?

• ? A Digital Flood Insurance Rate Map (DFIRM) is

  electronic format within GIS.

• (2) flood hazard information
• (3) a panel collar

How is a DFIRM Made?

• ? GIS base map data is obtained, usually from

  a countywide basis).

  digitized/converted into a GIS from original work
  maps or FIRM panels.
