Remote Sensing
• Used for a wide array of projects– Satellites• Vegetation greeness used to calculate post fire severity• Looking for new fire starts
• At wildfire incidents– Airplane • Aerial photography -Help calculate perimeters and
acreage• Infrared pictures to look for the last hot spots
Incident Action Plan
• Prepared every day– Distributed at morning briefings– Contains assignments for the day
• Daily updates of maps, created by GIS specialist– Fire perimeter– Acreage– Division breaks– GPS units play an integral role in collecting data
Limitations
• All models that predict fire behavior are based off of the same equation.
• There are too many variables in the real world to accurately predict fire behavior and movement.
• Recreating past fires with a model is difficult even with all the available information. – It takes years of experience and manipulating data
to accurately depict a historic fire.
