  20. 20. ConclusionsThe proposed methodology of ArcFuel is still being developed and modified. Tests in theGreek pilot area provided good results so farIt 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 areaswill be testedThe proposed approach can provide a semi-automatic production chain of forest fuel maps inEU countriesThe ArcFuel map production chain can provide accurate and reliable maps for all EU countriesat spatial resolution of 50 m, based primarily on existing spatial datasetsThe ArcFuel maps can be available for operational use with forest fire behavior applicationsand fire simulators in frame of modern forest fire management organization 20 3rd International Conference on Modelling, Monitoring and Management of Forest Fires 22 – 24 May, 2012, New Forest, UK
