Problems solved by technology

[0003] At present, the method of map update is mostly to re-download the new map version, instead of only downloading the updated part of the map data, and also cannot update across map versions. In this way, due to the large amount of downloaded data and the large amount of traffic, it not only wastes users A large amount of network traffic, and waste the user's time to update the map, which brings inconvenience to the user's travel

Abstract

The invention provides a map data updating method, an apparatus thereof and a server. The map data updating method comprises the following steps: receiving an update request of a first map data sent by a terminal, wherein the update request contains the version information of the first map data; according to the version information, searching the first map data corresponding to the version information; performing differential calculation on the first map data and a second map data corresponding to a latest version, sending the differential data obtained through differential calculation to the terminal, and updating the first map data by the terminal. The method saves the network flow used for updating the map data and reduces the updating time for the map data.

Description

technical field [0001] The invention relates to a data updating technology of a navigation electronic map, in particular to a method, a device and a server for updating map data. Background technique [0002] At present, with the increase of people's travel, the application of navigation electronic map is gradually increasing. Navigation electronic maps are mostly used in various user terminals such as mobile phone terminals, navigation terminals, and personal computer terminals. These terminals are based on communication networks such as the Internet and mobile base stations. Users can plan routes according to the maps on these terminals. When the road is repaired, the map data map merchant will update the map data according to the new road planning. Therefore, in order to avoid using outdated data for route planning, positioning and retrieval, the user needs to update the existing map data on the terminal in time. [0003] At present, the method of map update is mostly ...
