In order to achieve the electronic map disaster recovery and automatic routing, a novel disaster-tolerant navigation algorithm（DTNA） is proposed based on electric power equipment coordinate vestiges. The algorithm core idea, unit structures, vestige data structures and processing flows are given. The information fusion methods and electric power equipment coordinate vestiges are used to generate feasible ways automatically. And the algorithm used bi-dimensional space to match way information and way-finding needs. The simulation results show that DTNA has better time consumption and less computing consumption than the GPS-discovery algorithm.
