We are remapping itbecause mapping science has created new information that was not previouslyavailable, which will allow us to be better prepared for fires, said JuneIljana, spokeswoman for the California Department of Forestry and FireProtection. The remapping effort incorporates improved wildland fire behaviorscience, data sets and understanding of structure ignition mechanisms duringwildfires.
