Description
Technical Field
The invention relates to the technical field of geographic information, in particular to a system and a method for custom map matching of a vector tile electronic map.
Background
At present, the electronic map Tiles mainly adopt two modes, one mode is a traditional grid tile, and the other mode is a Vector tile (Vector Tiles), wherein the traditional grid tile adopts a classification mode of a quadtree pyramid model to cut a map into countless rectangular grid pictures with equal size, and the rectangular grid pictures are spliced into maps with different levels according to certain rules for display. The vector tile is similar to a grid tile, vector data is divided into vector element description files by a multi-level model and stored in a server side, then the vector element description files are rendered and drawn to a client side according to a specified style, and geometric information and attribute information projected in a rectangular area are stored on a single vector tile. And finally, rendering and outputting the map at the client after the client acquires data such as vector tiles, map labeling fonts, icons, style files and the like through a distributed network. The vector TILEs have no unified data labels, and MAPBOX center TILE specific general vector TILE data standard is established by MAPBOX center TILE standards based on Google protocol buffers and is adopted by many companies and organizations. The vector tiles can be rapidly rendered on the client, and the rapid development of a map rendering engine is promoted mainly due to the development of a client graphics rendering technology, common graphics rendering technologies include OpenGL/WebGL and the like, while OpenGL and WebGL are bottom-layer 3D graphics technology labels, and many map rendering engines are derived according to the standards, such as an open-source 3D rendering engine Tangram (including a browser rendering engine Mapbox GL JS and a mobile terminal rendering engine tagram-ES, which are provided by mapzen open sources) using an OpenGL graphics API, and a Mapbox GL map rendering engine (including a browser rendering engine Mapbox GL JS and a mobile terminal rendering engine Mapbox GL nat) used by Mapbox.
The grid tiles are rendered in advance, so that the requirements on the performance of the client are low, and the performance is stable. The tiles have high occupied space, the tile map cutting efficiency is low, the map style cannot be dynamically adjusted at any time, the map resolution is low, and the loading speed is slow. The vector tiles have the advantages of low occupied space, high tile map cutting efficiency, quick map rendering effect, capability of dynamically adjusting the map style at any time and high map resolution. The requirement on the performance of the client is high, and the compatibility of the old equipment is problematic. Although the vector tile open source technology blooms all the time, the custom vector tile electronic map cannot be manufactured.
