Fig. 8

Illustration of areas defined as partially burned. The top panel shows an area with mixed burned and unburned pixels (a). The middle panel shows burned patches at the beginning of the fire season (d) and the same area later (e) during the fire season. Burned areas (b) and (f), consist of contiguous groups of burned pixels with a definite fire scar. A mix of burned and unburned pixels and those with a diminishing fire scar were defined as partially burned, shown in (c) and (g) when combined with burned areas. Detection of burned areas with a diminishing fire scar is desirable when an image from an earlier date during the fire season is not available.
