Fire danger rating is the process of systematically evaluating and integrating the factors that determine the ease of a fire starting and spreading, the difficulty of control, and the resulting impacts based on an assessment of ignition risk, the fire environment (fuels, weather, and topography) and values at risk. The Atlas of Canada has mapped each year from 2001 to 2009 the daily forest fire danger ratings in partnership with the Canadian Forest Service, Natural Resources Canada. Only the forest fire danger rating for the last recorded day of fire danger rating for the year 2009 has been archived. The original data from 2001 to 2009 are available from the Canadian Forest Service, Natural Resources Canada.
