The historical rate of spread scale is based upon previous large-scale brushfires, while the real time scale utilizes GPS technology. The historical rate of spread scale is designed to address two brush fire environments. These environments are a brush fire occurring under Red Flag conditions and a brush fire occurring under Non-Red Flag conditions, and references are placed on the tool at each 30-minute time zone.
