Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0052] figure 1 It is an application environment diagram of a map data query method in an embodiment. refer to figure 1, the application environment diagram includes a server 110 . The server 110 obtains the geographic location to be queried, and determines the map grid code to be queried corresponding to the geographic location to be queried according to the first map grid where the geographic location to be queried is located. Then, the server 110 queries the target map grid file in at least two map grid files pre-divided from the map according to the map grid code to...

Abstract

The invention relates to a map data query method and device, a computer readable storage medium and computer equipment. The method comprises the steps of obtaining a to-be-queried geographic position;determining a to-be-queried map grid code corresponding to the to-be-queried geographic position according to the first map grid where the to-be-queried geographic position is located; querying a target map grid file in at least two map grid files pre-segmented from a map according to the to-be-queried map grid code, wherein map data in the target map grid file corresponds to the same second mapgrid, the second map grid is a map grid obtained by pre-segmenting in a map according to the target map grid file, the map grid code of the second map grid is matched with the to-be-queried map grid code; and loading the target map grid file to obtain target map data in the loaded target map grid file. By adopting the method, the map data query efficiency can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a map data query method, device, computer-readable storage medium and computer equipment. Background technique [0002] An electronic map is a map stored and consulted digitally using computer technology. High Definition Map (HD Map) is an electronic map that can provide lane-level navigation information. [0003] However, in order to provide lane-level navigation information, high-precision maps often have a large amount of information, and often need to use large-scale database tools to realize spatial query of high-precision map data, which is difficult for embedded processing devices with limited processing resources. It needs to consume a lot of processing resources, and also makes the query efficiency of map data not high. [0004] Therefore, in the current map data query method, there is a problem that the query efficiency of the map data is not high. Conte...
