Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] figure 1 It is a structural diagram of an electronic map system, see figure 1 , the system includes a terminal device 10 and a vehicle-mounted terminal 20, wherein the terminal device 10 includes but is not limited to a smart phone, a tablet computer, a smart wearable device, etc., and the vehicle-mounted terminal 20 may include the aforementioned instrument panel. The electronic map application is installed in the terminal device 10. The electronic map application can not only display the map on the navigation map of the terminal device, but also display the map on the desktop widget of the terminal device, and can also display the map on the dashboard of the car. The above display methods can be completed by three instances o...

The invention discloses a method, device, terminal device and storage medium for processing map data, and belongs to the technical field of maps. The method comprises the following steps of: acquiringa map block data request of any instance of an electronic map application, wherein the map block data request comprises at least one data index of the map block data, the electronic map application comprises at least two instances; acquiring the map block data corresponding to the data index in the map block data request; caching the map block data to a common data cache area, wherein the commondata cache area is a cache area commonly accessed by at least two instances in the electronic map application. According to the invention, when the electronic map application works, the map block datarequested by different instances is stored in the common data cache area, and because the common data cache area is accessed by the at least two instances in the electronic map application, the map block data cache is not needed to be provided for each instance, and the storage resource required by the map block data storage is saved.
Description
technical field [0001] The present invention relates to the field of map technology, in particular to a map data processing method, device, terminal equipment and storage medium. Background technique [0002] With the development of technologies such as the Internet and mobile terminals, electronic maps have become an indispensable part of people's daily life. [0003] In some electronic map applications, the electronic map application may provide multiple instances (Instance), and the multiple instances display maps in different forms. For example, the electronic map application provides three instances, the first instance is displayed through the navigation map on the main interface of the electronic map application, the second instance is displayed through the desktop widget (widget), and the third instance is displayed through the dashboard of the car. show. [0004] During the working process of these multiple instances, each instance is independent of each other, and...
