The paper presents the assumptions for the computer simulation of a forest fire in according with digital topographic map of forest and short-term weather forecast. To conduct the simulation, a software has been created. The software includes deterministic mathematical model of a forest fire. Input data have been extracted from the short-term weather forecast and the digital forest maps. The application range covers both planning of a controlled fire, e.g. in cases when the fires are intentionally started by the forest services to get rid of accumulated forest material, as well as to plan extinguishing actions and to plan appropriate disposal of resources during the extinguishing of a forest fire. Creation of the described simulation environment arises from the need of optimum planning of the extinguishing actions in local fire service centers. The initial risk assessment in the stage of planning the extinguishing action, will allow efficient management of equipment by the local units. It also prevents from repeating wrong decisions made in the early stages. This need imposes limiting the use of equipment platforms to medium class PC.s. The outcomes of the paper provides accessibility of a tool supporting the decision making process and assessing the damages in the high risk conditions of a forest fire. Furthermore, conducting a simulation allows to estimate the need for fire fighting equipment in the case of total and border extinguishing of a fire, for different weather conditions, considering fire density.
