5. Applying Of Imaging Scale
After computing of the primary area of the burnt region, a coefficient, such as "m",
should be calculated according to equations (1) and (2). By applying the imaging scale
on it, real area is obtained according to equation (3) based on the measurement of forest
land surface area [15];
Imaging Scale = Camera Focal (f) / Flight height (h) (1)
m = 1 / Imaging Scale (2)
Real Area = Primary area * m (3)
In the sample image, if we have the values of "f" in millimeter and "h" in meter;
therefore, real area obtained in hectare
