Abstract

The embodiment of the invention discloses a map data processing method and a location-based service providing method, and the method comprises the steps: displaying map vectorization data corresponding to a target map element in a map vectorization data editing window, displaying a map modeling rendering result corresponding to the map vectorization data in a map modeling rendering window; in response to an editing operation of a user on the map vectorization data in the map vectorization data editing window, obtaining editing data of the map vectorization data; and updating a map modeling rendering result displayed in the map modeling rendering window based on the editing data. The technical scheme belongs to the technical field of geographic information, can assist a user in understanding semantic information of the map vectorized data, and improves the editing accuracy and efficiency of the user on the map vectorized data, thereby improving the production efficiency of high-precision map data, and solving the technical problem of how to assist an operator in understanding the map vector data.

Description

technical field [0001] The present disclosure relates to the technical field of geographic information, and in particular, to a method for processing map data and a method for providing location-based services. Background technique [0002] With the development of location-based services (LBS), more and more application software integrates the service capabilities related to electronic maps. At the same time, electronic maps also begin to evolve from standard maps to high-precision maps. Based on high-precision maps, it can support scenarios such as smart city management, lane-level navigation, assisted driving, advanced assisted driving, and automatic driving. Currently, high-precision maps are mainly used for autonomous vehicles. [0003] In the high-precision map data, the road data in the real world is expressed as abstract vector data in the form of points, lines, surfaces, etc., and then model rendering is performed on the basis of the vector data in the form of points...
