Forest Fire Risk Index FHI (fire hazard index) a measure of that part of the fire danger contributed by the fuels available for burning and topological characteristics of the particular forest area FDI (fire danger index) the chance of fire commencement, as affected by the nature and incidence of meteorological causative parameters FFRI (Forest Fire Risk Index)
4
FHI (fire hazard index) FHI = 0.4 * n + 0.15 * s + 0.05 * a + 0.12 * r + 0.10 * h + 0.13 * v parameters nature: n : vegetation type (nature) s : terrain slope a : orientation of the terrain r : proximity of the terrain to roads or paths h: proximity of the terrain to power lines v : proximity of the terrain to settlements and uncontrolled waste disposal sites

Evaluation of FHI Classification on five (5) risk categories for FHI, FDI and the combined FFRI : – Category 1 : 0 – 1. (VERY LOW - GREEN COLOR) – Category 2 : 1.01 – 2. (LOW – LIGHT BLUE COLOR) – Category 3 : 2.01 – 3. (MEDIUM- YELLOW COLOR) – Category 4 : 3.01 – 4. (HIGH – ORANGE COLOR) – Category 5 : 4.01 – 5. (VERY HIGH - RED COLOR)

Send e-mail when predetermined areas fire risk exceeds a predetermined level of risk Modify shapefile protectionArea for the areas of interest of the responsible of Civil protection and designation of these areas. -Entries for the e-mail sending -When a new map is created all regions set by the operator are controlled and if the FFRI has surpassed even at in one pixel the risk limit set, an e-mail is sent. Determine the template of the e-mail that the operator will receive.
