Problems solved by technology

[0004] However, in the existing scale switching, since all scales use the same data package, the system needs to extract the display data in the data package, and the extracted data can only be displayed on the display after thinning and merging. On the interface, the speed of zooming is slow, resulting in a sense of hysteresis

Abstract

The embodiment of the invention discloses a processing method and a processing device for realizing map display, which are used for displaying maps in a navigation system. The method disclosed by the embodiment of the invention comprises: receiving a map scale switching instruction, wherein the scale switching instruction comprises the grade of a measuring scale needed by a current display interface for displaying a map; acquiring a display layer data packet corresponding to the grade of the measuring scale, wherein the display layer data packet is obtained by tiered storage, data vacuation and data merging; and displaying the corresponding map on the current display interface according to the display layer data packet. The embodiment of the invention also provides a device corresponding to the method, which can reduce the time for switching the map frame on the display interface and eliminate delay feel.

Description

technical field [0001] The invention relates to the field of map display in navigation, in particular to a processing method and device for realizing map display. Background technique [0002] With the rapid development of science and technology, the navigation system has also made great progress. Among them, the vehicle navigation system is more and more used by the general public, effectively improving the quality of life of the people. [0003] In the navigation system, when the scale is switched, it is a common function of the navigation system. Users have different map browsing needs and use different scales at any time. When you need to see local details, you can use a large scale, that is, zoom in on the map and zoom in on the vision. [0004] However, in the existing scale switching, since all scales use the same data package, the system needs to extract the display data in the data package, and the extracted data can only be displayed on the display after thinning ...
