The digitalization of contour lines of the study area (at
1:50,000) was used to establish the digital elevation
model (DEM). This was the basis on which we have:
Establish the elevation Map source of calculating the
index of continentality [Formula 3].
Establish maps of slopes and exposures, sources of
calculating the index topomorphologique
The field investigation, undertaken during the year
2010, allowed collecting data of dominant species, their
sizes and their recovery. These field data were used to
calculate the index of combustibility by Formula .
Climatic station data (temperature, rainfall, relative
humidity and wind, on the period 1990-2010) were used
to calculate the drought index and the wind. Spatialization
of the two indices was determined by interpolation.
The combination of the three layers, has
given the climate index map
The superposition of the digital map of the road network
with the map of forest areas (vector layers), have
been identified the index of the human effect
on the starting lights .
The combination of the four resulting layers (IC, IM,
and IH ICL) gives us the map of forest fire hazard
