At present, there is no conventional scientific method to evaluate the area of the
burnt regions of forests and in this field, the related organizations use different
methods and variables. Also, the speed in performing the processes of area
computing and damage evaluation, especially in the extensive damaged forest
regions is very slow; consequently, the expression of results takes more time. Now,
one of the most important parameters to evaluate the forests fire damages is
computing the area of the burnt forest regions. In this research, an aerial digital
image from a forest region after fire occurrence is used and the primary area of the
burnt region is calculated in two methods of; integration and interconnected
components extraction, by using image processing techniques. Also, in order to
estimate the real area, a coefficient "m" is calculated to obtain real area based an
measuring the forest land surface by exerting the imaging scale on the primary area.
The methods which are introduced to calculate real area of the burnt regions, are
dependent on some secondary tools such as aerial camera and special plane, but in
the extensive forest regions damaged by fire, they cause to decrease in the
evaluation costs and faster notification of the results.
