Using the a hand-hold GPS and wireless transmitting unit to rapidly locate the fire and determine the rate of fire spread, which also offered an indispensable way of verifying the speed of forest fire appealing. Discussing the representation and Computing Method of the simulate calculation error based on the thorough investigation of the sources of simulate calculation error. Pointing out that the speed and directional error are the root of forest fire appealing simulates error. Thus increasing the parameter of error correction is an effect way of reducing systematicsimulationerrors.
