Embodiment Construction

[0035] The inventor found that in the prior art, the usual method of compiling map data is to develop different compiling tools according to the specifications of map data provided by various suppliers. If a supplier is changed, a new compiling tool needs to be developed. For navigation system manufacturers, the cost of system development is high and the compilation cycle is long.

[0036] E.g, figure 1 What is shown is a schematic diagram of the working mode of the navigation system server processing original map data in the prior art. refer to figure 1 , first, the navigation system server obtains map data from different map databases (such as map database 101, map database 102 and map database 103), wherein the specifications of the map data are not the same, so the navigation system server needs to obtain map data according to different suppliers ( Assume that the map data provided by suppliers A, B, and C) are included and loaded separately, such as figure 1 The suppli...

Abstract

The invention provides a processing method based on map data, a navigation system server and a navigation system. The processing method based on the map data comprises the following steps of: when original map data is loaded from a map data providing system, carrying out corresponding configuration on a loading process based on specifications of the original map data; obtaining the original map data from the map data providing system based on the configuration; converting the original map data into target map data based on the configuration, wherein with regard to different specifications of the original map data, the specifications of the converted target map data are the same; and compiling the target map data to generate navigation map data. With the adoption of the technical scheme, the map data provided by different suppliers can be realized, so that the efficiency of processing the data is improved and the development complexity of the navigation system is reduced.

Description

technical field [0001] The invention relates to the field of navigation systems, in particular to a processing method based on map data, a navigation system server and a navigation system. Background technique [0002] With the development of the automobile industry, people pay more and more attention to the user experience when using a car while owning a car. Existing in-vehicle devices can already provide users with many services, including services for multimedia needs such as music, video, and pictures, as well as driving navigation services such as real-time traffic information and destination maps. In particular, the use of car navigation systems is becoming more and more popular. The voice prompts of the navigation system can guide the car owner to drive, especially when the car owner is driving in an unfamiliar city, the car owner can help the user reach the destination conveniently and quickly through the navigation system. [0003] For navigation system manufactur...
