Research Objective

Produce maps of interface

areas across Canada.

?also…

Provide basic statistics on the interface and

perform analysis of spatial patterns.

Wildland Fires

17% of fire polygons from 1980-2014 are

“wildland-urban interface fires”

but 6% for lightning-caused fires

and 39% for human-caused fires

Applications of the Interface MapsThe three maps of interface areas (urban, industrial,

and/or infrastructure) will be freely available.

Can easily be combined with other spatial data.

Can be used in multiple applications:

• FireSmart• Fuel treatments• Building codes• Municipal bylaws• Industrial fire regulations• Infrastructure fire mitigation

• Resource prepositioning • Fire prioritization• Interface fire alerts• Values protection• Incorporate into risk models

• City planning• Evacuation planning• Insurance• Fire management budgeting, purchases• Railway policy/planning• Powerline safety
