Problems solved by technology

[0004] During the research and practice of the prior art, the inventors of the present invention found that, because the offline data packets are relatively large, it not only consumes more bandwidth flow for users, but also wastes the storage space of the server, and also greatly reduces the Improve the efficiency of offline data packet production, increase the cycle of map data update, and reduce the efficiency of the client when updating map data

[0055] see figure 1 , figure 1 It is a schematic flowchart of the map data processing method provided by the first embodiment of the present invention. Wherein, the method steps include:

[0056] In step S101, map data update information is acquired, and an area to be updated and an update range within the area are acquired according to the map data update information.

[0057] In step S102, a map incremental package is generated according to the area and the update range in the area.

[0058] It can be understood that the steps S101 and S102 may specifically include:

[0059] Wherein, the map data processing method provided in this embodiment is performed based on the server side; optionally, in this embodiment, a map basic data package (also referred to as a map baseline package) may be preset in the server, and the The map basic data package is generated based on the map basic data.

[0060] For example: taking a city as a unit, first of all, the national map offline p...

[0069] see figure 2 , figure 2 It is a schematic flowchart of the map data processing method provided in the second embodiment of the present invention. The method steps include:

[0070] In step S201, map data update information is acquired.

[0071] In step S202, it is judged whether the full amount of data needs to be updated.

[0072] It can be understood that the steps S201 and S202 may specifically include:

[0073] Wherein, the map data processing method provided in this embodiment is performed on the server side.

[0074] After the server obtains the map data update information, it can predict the capacity of the generated map incremental package according to the map data update information, so as to judge whether it is necessary to update the full amount of data; wherein, the full amount of data can refer to the whole country Updating the full amount of map data means that, in combination with map data update information, the original map basic data package nee...

Embodiment approach

[0080] In one embodiment, when it is determined that the full amount of data needs to be updated, basic map data is acquired and a basic map data package is generated according to the basic map data. For example, with the city as the unit, the offline package data of the national map is fully updated to generate a basic map data package; at the same time, a major version number is assigned to the basic map data package (that is, a version identifier is specified). For example, if the version data with the major version number of Beijing is generated as 29, the data will be named: beijingshi.dat before packing, and beijignshi29.zip after packing. It can be understood that, in some implementations, the basic map data package may be generated according to the obtained basic map data, and then it is determined whether the full amount of data needs to be updated, which is not specifically limited here.

[0081] Among them, the version number is the identification of map data repres...

Abstract

The invention discloses a map data processing method, device and system. The method includes the steps that map data update information is obtained, and an area needing to be updated and an update range in the area are obtained according to the map data update information; a map incremental packet is generated according to the area and the update range in the area; update prompt information is generated according to the map incremental packet, and the update prompt information is sent to a client; a first request update instruction sent by the client according to the update prompt information is received, and the first request update instruction indicates download of the map incremental packet; the map incremental packet is sent to the client according to indication of the first request update instruction. The map incremental packet is generated and sent to the client to be updated and downloaded so that the size of updated data packets can be greatly reduced, a user can download the updated data packets conveniently, the update period is shortened, waste of server resources is reduced, and user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a map data processing method, device and system. Background technique [0002] With the continuous popularization of mobile navigation technology, more and more people begin to rely more and more on navigation for route guidance on unfamiliar roads, which greatly improves the convenience and accuracy of people's wayfinding. [0003] At present, map products generally provide some basic data for map display to users as an offline data package. The user can download the offline data package to the local client to assist the use of the map. In order to ensure the timeliness of the map, users often need to update these offline data packets, and in the prior art, for the update of offline data packets, the method of full replacement is often adopted, that is, when there is data to be updated, the map data The provider will upload the full amount of data packets to ...
