The helicopter rescue is an important component in emergency rescue system.Helicopter rescue often happens un der complex terrain,in order to make the helicopter reach the rescue point in the least time,the best flight path must be ob tained.This paper first selects a typical complex terrain in the southwest.Then builds a helicopter rescue flight path network with Supermap software,and takes time as impedance factor to endow the weight of flight path network.Finally obtains the optimal flight path for helicopter rescue under complex terrain by using Dijkstra algorithm.
