A spatial representation of the burn severity of historical wildfires starting in 2015. The previous year's wildfires are updated after a year delay in order for the proper imagery to be obtained. Burn severity is estimated from analysis of pre- and post-fire LANDSAT 8 satellite imagery of the fire perimeters area. A burn severity rating of High, Medium, Low, Unknown or Unburned is provided.
