Abstract
Although forest fires are commonly accepted as a natural part of the ecosystem, frequent forest fires present great challenges to fire managers. In this research, ‘Fire Area Simulator’ has been used to simulate and study forest fire behaviour. Once the predicted perimeters were generated and compared to those shown in postmortem aerial infrared images, partial agreement was observed for the direction and extent of the forest fire. Using spatial analysis functions, the characteristics of the damaged areas were also observed. It is shown that constructing fuel models and collecting weather data with regard to local and regional forest fires can improve the simulation of forest fires. The spatial modelling of landscapes in aerial infrared images can be used for the evaluation of the extent of damage due to forest fires.
