AratosFire is a fire Simulation Tool. It uses spatial information on topography and fuels along with weather and wind files. It incorporates existing models for surface fire, crown fire, spotting, post-frontal combustion, and fire acceleration into a 2-dimensional fire growth model. AratosFire is a tool for predicting wildland fire behavior using widely recognized algorithms. AratosFire is for users who need a highly optimized application programming interface for predicting fire behavior growth simulators.AratosFire has been very helpful in many cases of fire incidents.
