Abstract

The application discloses a map, a map generation method, a map use method and device. The map generation method comprises the following steps: obtaining a plurality of positioning data of a group of position points, a plurality of positioning quality reference information and position information of map elements (for example, roads or lanes) in a map; determining a target geographical range and a plurality of position points in the target geographical range based on the plurality of positioning data, the plurality of positioning quality reference information and the position information of the map elements, wherein the plurality of position points are part of the position points or all of the position points in the group of position points; generating positioning quality indication information according to the positioning quality reference information of the plurality of position points to indicate a positioning quality statistical value in the target geographical range; and finally, the positioning quality indication information can be added to the map. The application provides a map with better positioning reference, so that a vehicle or the like can selectively use positioning information in a high-precision map.
