Abstract

The invention relates to a map data query method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a current position of a vehicle; requesting map data matched with the current position from a cloud database; caching the requested map data in the local; constructing a spatial index of the map data locally according to road elements in the map data; and when a query request sent by an application layer is obtained, querying map data corresponding to the query request from the local through the spatial index. According to the scheme, system storageresources can be saved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a map data query method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of science and technology, various technologies emerge in an endless stream, and the application of map technology is becoming more and more extensive. For example, in the process of driving a vehicle, it is necessary to query and use map data in order to provide accurate information for the driving of the vehicle. [0003] In the traditional method, the full amount of map data needs to be stored in the vehicle terminal. During the driving process of the vehicle, the full amount of map data needs to be preloaded, and then the corresponding map data can be queried from it. Obviously, the traditional method requires excessive consumption of system memory resources. Contents of the invention [0004] Based on this, it is necessary to provide a map da...
