VANCOUVER - An infrared scan has been completed of a large wildfire in northeastern B.C., in an effort to confirm the perimeter of the out-of-control blaze that's threatening a community and a key hydroelectric dam.
The B.C. Wildfire Service says the scan was done late Tuesday.
Helicopters will be supporting by providing water to cool the edges of the fire. Wildland firefighting takes a variety of tactics and techniques, including indirect attack using ignition operations to slow or steer the progress of a fire.

It will also be used to identify hot spots on the east flank of the 287-square kilometre wildfire, nearest to the W.A.C. Bennet Dam and the evacuated community of Hudson's Hope.
The wildfire is now the only one in B.C. where evacuation orders remain in effect after residents of about one dozen properties east of Vancouver were allowed to return to their homes on Tuesday.
The District of Hope and Fraser Valley Regional District lifted orders and alerts posted last weekend along the south side of the Fraser River west of Hope as lower temperatures and light showers calmed the fire, although it remains out of control.
It has generated significant amounts of smoke and, along with a large fire east of Hope, another in southeast B.C., and others in Washington state and Idaho, is blamed for affecting air quality across large parts of B.C. and Alberta, with conditions not expected to improve until Friday or later.
