Embodiment 1

[0056] refer to figure 1 , which shows a flow chart of specific steps of a method for updating map information provided in Embodiment 1 of the present application.

[0057] Step 101, receiving a real-time update request, where the real-time update request includes a target area and a target scaling factor.

[0058] The embodiments of the present invention are suitable for updating electronic maps, for example, displaying and updating maps in real time on terminals with screens such as mobile phones and tablet computers.

[0059] Wherein, the target area is a map area displayed on the display screen, which is related to the display screen or the setting of the display area. Since the display screen or display area is generally rectangular, the target area is generally rectangular. Certainly, when the display screen or display area is circular or other shapes, the target area is also circular or other areas.

[0060] The target zoom factor is the zoom factor currently used by...

Embodiment 2

[0071] refer to figure 2 , which shows a flow chart of specific steps of a method for updating map information provided in Embodiment 2 of the present application.

[0072] Step 201, for each road information in the preset road information database, determine the level corresponding to the road information.

[0073] Wherein, the road information database may store corresponding road information in units of countries, provinces, and cities. For example, the road information database corresponding to a country can store road information in the entire national geographic area; the road information database corresponding to a province can store road information in the entire provincial geographic area.

[0074] Road information may include: road signs, road names, and road coverage areas.

[0075] The level of road information can be understood as the importance of the road, the higher the level, the higher the importance; the lower the level, the lower the importance.

Embodiment 3

[0120] refer to Figure 4 , which shows a structural diagram of an apparatus for updating map information provided in Embodiment 3 of the present application, and the details are as follows.

[0121] The real-time update request receiving module 301 is configured to receive a real-time update request, where the real-time update request includes a target area and a target scaling factor.

[0122] The target road information update module 302 is used to obtain target road information from the preset spatial data index library according to the target area and the target zoom factor, and update it to the display interface; wherein, the spatial data index library is based on the candidate zoom factor Default road class generation.

[0123] A target road condition information update module 303, configured to acquire target road condition information from the target cache according to the target road information, and update it to the display interface.

[0124] To sum up, the embod...

Abstract

The present application provides a map information update method, device, electronic device and storage medium, the method comprising: receiving a real-time update request, the real-time update request including a target area and a target zoom factor; zooming according to the target area and target The coefficient obtains the target road information from the preset spatial data index library, and updates it to the display interface; wherein, the spatial data index library is generated according to the preset road level of the candidate scaling factor; it is obtained from the target cache according to the target road information The target traffic information is updated to the display interface. Static road information can be preloaded and displayed, and then dynamic road condition information can be loaded in real time, which helps reduce the amount of data returned to the front end at one time and reduces the instantaneous occupation of resources.

Description

technical field [0001] The embodiments of the present application relate to the technical field of terminal equipment, and in particular, to a map information updating method, device, electronic equipment, and storage medium. Background technique [0002] With the intelligentization of terminal devices, navigation systems have shown great potential on terminal devices, and users can reach any target location through navigation systems on terminal devices such as mobile phones, tablet computers, and personal computers. While displaying road information, it can also display real-time traffic information of the road to further improve user experience. [0003] In the prior art, the main steps of displaying real-time road condition information include: first, classify the static road network information to obtain road grades, and establish a mapping relationship between road grades and zoom factors; then, zoom in and out through the requested target area and display The coeffic...
