During my postgraduate degree I had to design a risk map for the spread of forest fires throughout Greece. This was created using different topographical layers and various indices which affect the spread of forest fires, and providing a table of risk for each layer based on their values. These values were then summed to create an overall risk map. Each layer is presented below (CTI = Compound topographic index; HLI = Heat load index).
The overall risk map is presented below, with the 4 risk levels seperated by their total values from the topographical and index layers. Here we see that the burn scar (from a previous fire in 2006) falls mainly within high risk areas, and as such, any reforestation efforts should be concentrated on the border of the burnscar, as seen in the bottom image, to minimise the chance of forest fires spreading.
