Abstract

The invention relates to a vector map generation method and device, electronic design and a computer readable medium. The method comprises: acquiring map position data and authority data to be drawn;determining drawing container data according to the map position data, wherein the drawing container data comprises vector tiles and a plurality of layers; traversing the plurality of layers accordingto the authority data to extract symbol codes; and rendering the symbol code and displaying the symbol code on the vector tile to generate the vector map. According to the vector map generation method and device, the electronic design and the computer readable medium, vector data can be visualized, and then map drawing is achieved at the browser end.

Description

technical field [0001] The present disclosure relates to the field of computer information processing, in particular, to a vector map generation method, device, electronic design and computer readable medium. Background technique [0002] With the development of computer technology and the Internet, building a geographic information system based on the B / S architecture significantly simplifies the deployment of the client system, reduces the difficulty of use by users, and greatly improves the maintainability of the system. The current mature vector data visualization technology is to store and manage the map data through the background, draw the data on the server side and cut it into tiles for storage, and obtain and display it by the browser. This kind of image-based display on the browser has many problems. Due to the insufficient ability of the browser itself to support graphic visualization, the online display of the current mainstream network geographic information s...
