What is Linear Source

Human activity causes forest fires near the municipalities and different transportation structures. It is suggested to define linear objects that caused human activity and the similarity of the human activity spread and heat conduction applicable for numerical simulation. The numerical parameter of the human activity is the virtual (possible) number of forest fires (VNF) near the linear object. One-dimensional and two-dimensional numerical models to evaluate the distribution of human activity from linear objects are presented. It is possible to mark out following linear objects: country roads, motorways, and railways. Dependence of the VNF for typical data from linear objects of human activity changed through the time and space are obtained. Conclusions are drawn about the patterns of human activity from linear objects. The prospects of further development are described for this direction to design software for forest fire danger prediction.
