The example in Fig. 4.4 presents the case of distance to urban centers criteria (S1,
for the first social criteria) in relation to forest fire ignition probability. Considering
the high impact of anthropogenic factors to wildfire ignition phase as reported by
the current literature, it is decided that the closer to urban centers (the smallest the
distance number), the higher the chances of a forest fire ignition event.
As a result, there are 13 new fields produced with relative values between 1 and
10. The spatial representation of these values is delivered in Fig. 4.5. It includes the
maps of all criteria reclassified into 10 classes and represented in red-yellow-blue
color gradient. According to the legend, the reddish zones indicate the highest values.
In other words, it indicates the areas within the forest surfaces that have the highest
chances of a wildfire ignition event caused by each criterion individually.
According to Fig. 4.5, the higher the distance of reference points to the elements
of social criteria the more bluish their color indicating the less likely areas of forest
surfaces which may face a wildfire ignition. For example, the color ramp distribution
in the cases of the distance to urban centers (S1) and settlements (S2) are different
even though both are targeting the human settling activity. While the former is referring to the core urban areas (major cities), the latter is targeting any settlement
including small villages as well.
