Conclusions
The proposed methodology of ArcFuel is still being developed and modified. Tests in the Greek pilot area provided good results so far
It will be tested and validated in context of the ArcFuel project in pilot areas in Greece, Spain, Italy and Portugal.
Accuracy, efficiency and consistency of the methodology applied in large geographic areas will be tested
The proposed approach can provide a semi-automatic production chain of forest fuel maps in EU countries
The ArcFuel map production chain can provide accurate and reliable maps for all EU countries at spatial resolution of 50 m, based primarily on existing spatial datasets
The ArcFuel maps can be available for operational use with forest fire behavior applications and fire simulators in frame of modern forest fire management organization
