This fire atlas includes all 1972-2012 wildland fires at least 20 hectares (ha) or 50 acres in size that occurred within or intersected the Crown of the Continent Ecosystem in Montana, which is comprised of Glacier National Park, Great Bear Wilderness, Bob Marshall Wilderness, and Scapegoat Wilderness. There are two main components of this fire atlas; the first being a fire history shapefile depicting fire perimeters, and the second being raster files representing satellite-inferred burn severity for these fires. For fires that occurred from 1972 to 1983, burn severity is measured as dNDVI (delta normalized difference vegetation index), which is calculated using Landsat multi-spectral scanner (MSS) data. For fires that occurred between 1984 and 2012, burn severity is measured as dNBR (delta normalized burn ratio), RBR (relatived burn ratio), and dNDVI (delta normalized difference vegetation index), which are calculated using Landsat TM (thematic mapper), ETM+ (enhanced thematic mapper plus), and OLI (operational land imager) data.
