Embodiment Construction

[0026] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0027] Such as figure 1 As shown, the multi-source map vector tile rendering system based on the rule base of the present invention includes:

[0028] Rendering rule library module, which includes two parts: metadata set and rule set, which are used to extract and assemble rendering styles. Rendering styles are expressed by a series of rules describing styles. These style rules are modularly organized into style blocks. Act on various feature objects on the map; each style block is composed of several rules, and the style block has its corresponding scope;

[0029] Map component library module, which is used to shield the differences in organizational structure and access interface of multi-source data, and provide a unified resource access interface, including three parts: data preproc...

Abstract

The invention discloses a rule-library-based multi-source map vector tile rendering system, comprising: a rendering rule library module that includes a data set and a rule set and is used for extracting and assembling a rendering style, wherein the rendering style is expressed via a series of descriptive style rules, these style rules are modularly organized into style blocks that act on various element objects on a map, each style block is composed of a plurality of rules, and each style block has its corresponding scope; and other modules. The system of the invention can establish a component-based map data visualization frame and allow plug and play for components on a domain framework.

Description

technical field [0001] The invention relates to a rendering system, in particular to a multi-source map vector tile rendering system based on a rule base. Background technique [0002] The navigation electronic map application based on the second-generation satellite navigation system faces the characteristics of complex structure, multi-scale and large data volume of traditional geographic data. Lack of a unified algorithm and framework for spatial data access and visualization, cannot provide lightweight real-time map rendering support for embedded navigation application systems, and cannot be compatible with multiple map data formats and geographic data in multi-source map data Integrate and share. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-source map vector tile rendering system based on a rule base, which can establish a componentized map data visualization framework and realize plug-and-play o...
