The invention discloses a map display method which is applicable to being implemented in a navigation server. The method comprises the following steps that an electronic map is divided into multiple partitions according to attribute characteristics of the electronic map; interest points of each partition are classified; according to preset standards, a first score of each of the interest points of each class is obtained; according to a place of departure and a destination set by a user, a navigation route is obtained through calculation; in each partition where the navigation route passes, a certain interest point in which the user may be interested is searched for; distance weighting is performed on the first score of the found interest point, and a second score is obtained; according to the second core, a first number of interest points are shown to the user in the partitions where the navigation route passes according to the second score. The invention further discloses the navigation server and a navigation system.
Description
technical field [0001] The invention relates to the technical field of map navigation, in particular to an electronic map information display method, a navigation server and a system. Background technique [0002] With the popularization of smart terminals and mobile Internet, online navigation has gradually replaced the traditional offline navigation system. The path calculation of online navigation is completed by the navigation server. Compared with offline navigation, it does not need to install huge map files in the navigation terminal in advance, and reduces the requirement for the computing power of the navigation terminal. In addition, the online navigation software can obtain a more detailed map containing various POI (Point of interest) information from the navigation server, and the information is updated and maintained by the server uniformly, which is more accurate. For example, the user can conveniently check the gas stations, restaurants or bank information a...
