Figure 2 shows images of the CORINE polygons overlaid
on the burnt mask.
However, since the proposed methodology is intended for
mapping burnt scars in forested areas, we can conclude
that results of the methodology were satisfactory. A
detailed image of the CORINE overlay with the mask
area showing the different cover types affected by the fire
is presented in Figure 3.
In addition, the results of this project show how the
proposed BI transformation can be derived from satellite
imagery coming from different sources. The increasing
amount of high and medium spatial resolution imagery
will allow us acquiring imagery shortly before and after
the fire enabling a quick estimation of environmental
damages caused by forest fires.
