Abstract

The invention relates to a method and device for generating a vector map. Wherein, the method includes: based on the GIS tool, matching the vector map data to obtain a drawing style file; based on the drawing style file, obtaining an element layer configuration file and a rendering style configuration file of the vector map data; The element hierarchical configuration file compiles the map style file to obtain target vector data; based on the rendering style configuration file, renders the target vector data to obtain a vector map. The method and device provided by the embodiments of the present invention can provide a simple and WYSIWYG compilation experience, and complete the customization and adaptation of the two stages of compilation and rendering; reduce the threshold and difficulty of vector map data compilation; improve compilation efficiency and Data quality; the versatility and compatibility of the compiling system have been improved, and the source data in different formats and the customized compilation requirements of users can be realized.

Description

technical field [0001] The invention relates to the technical field of digital maps and geographical information, in particular to a method and device for generating vector maps. Background technique [0002] At present, the commonly used spatial data structures are divided into two categories: vector structure and raster structure. Among them, the vector structure has the characteristics of "obvious location, implicit attributes". High efficiency, easy to implement topology and network analysis. Therefore, map data with vector structure plays an indispensable role in the field of digital maps. [0003] In order to generate a vector map for display to users, it is necessary to compile and render map data of a vector structure (hereinafter referred to as vector map data). Among them, the compilation process of the vector map data is: compiling the source data in the vector exchange format (that is, the vector map data in the format of shape, mif, geojson, postgis, etc.) int...
