The invention discloses a map navigation method and apparatus. The method comprises: displaying a two-dimensional navigation map based on two-dimensional data on a client terminal; if the location of the terminal holding the client terminal is determined, acquiring a three-dimensional navigation map of a preset geographic target determined based on altitude data of the geographic target when a navigation route enters the edge range of the preset geographic target; and displaying the three-dimensional navigation map through the client terminal. The invention can improve the map-reading efficiency of the user and reduce the probability of error driving.
