Embodiment Construction

[0031] In view of the problems in the prior art that when the navigation topology data in the navigation electronic map is updated by using a complete update method, the update data volume is large, the time is long, and even the normal use of the terminal is affected, the two navigation electronic maps provided by the embodiment of the present invention A method for updating topological data, which can be executed by a device for updating navigation topological data in a navigation electronic map.

[0032] The process of the first method is as follows figure 1 As shown, the execution steps are as follows:

[0033] S10: communicate with the terminal.

[0034] It can communicate with the terminal through a wireless network or a fixed network.

[0035] S11: Detect whether the navigation electronic map stored in the terminal is the latest version, if it is the latest version, execute S12; if not, execute S13.

[0036] S12: There is no need to update the navigation electronic ...

Abstract

The invention discloses an updating method for navigation topological data in a navigation electronic map and a related apparatus. The method comprises: detecting whether a navigation electronic map stored at a terminal is a latest edition, if not, determining the grid information corresponding to the navigation topological data needing updating and sending to the terminal, wherein the grid information at least comprises boundary points of the grid and an adjacent grid, and road identification ID connected with the boundary points in the grid. The technical scheme helps to realize incremental updating of navigation topological data in the navigation electronic map at the mobile terminal.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for updating navigation topology data in a navigation electronic map and a related device. Background technique [0002] In recent years, with the explosive growth of mobile terminals, navigation electronic maps have also experienced rapid development. The navigation electronic map can provide guidance for the user to travel, and can still guide the user to reach the destination even if the user is not familiar with the road. The navigation electronic map has the characteristics of timeliness, accuracy and diversity, which contains increasingly rich, accurate and diverse geographic information and attribute information, and the data files containing these information are also becoming larger and larger. In order to maintain the navigation electronic map Accuracy and timeliness, data update of navigation electronic map has become one of the key issues affecting the dev...
