APPLICATION OF MULTICRITERIA GIS ANALYSIS IN DERIVATION OF THE WILDFIRE IGNITION INDEX AND OPTIMIZATION OF FIREFIGHTING INTERVENTIONS IN THE NP KRKA

Abstract

This paper demonstrates the possibilities of GIS implementation in the preventive phase of firefighting activities for the Šibenik-Knin County. Multicriteria GIS analysis (GISMCDA) was applied in derivation of the wildfire risk ignition index. Four groups of criteria were used: vegetation, geomorphometry, anthropogenic impact, and climate elements. Wildfire risk ignition models were derived based on the decision-maker method through (1) the experience of the local fire commander and (2) following the examples of good practice. Furthermore, the coverage and the passability of the National park (NP) Krka roads were analyzed in relation to the standard intervention time from the competent fire brigades. The nearest fire brigades and the fastest routes to the most endangered zones within the NP Krka have been derived. The results indicate that the area of Šibenik-Knin County belongs to the moderate/moderately high risk of fire ignition and that the coverage of the NP Krka roads within the standard intervention time is not satisfactory.
