Territorial space planning application-oriented space cartographic system and method

Abstract

The invention provides a territorial space planning application-oriented space cartographic system and method, the cartographic method is completed through mutual cooperation of a data conversion device and a graphic rendering device, after the data conversion device receives a cartographic thematic type, non-space relation data and space data are fused, and if the data is the standard data in the industry, a style required by the graphic rendering device is directly generated, otherwise, the data required by the graphic rendering device is converted according to the thematic type to generate the style. And various types of themes in the industry are processed through the rendering device, so that the themes are output on the map in a unified form. Various types of data conforming to the standard in the industry can be accessed, various types of thematic rendering modes realized on a map in the industry can also be accessed, and only various thematic rendering tools conforming to the interface specification need to be provided.

Description

technical field [0001] The invention relates to the technical field of spatial mapping, in particular to a spatial mapping system and method oriented to the application of national land space planning. Background technique [0002] Among the existing front-end mapping technologies, the third-party libraries Echarts and Heatmap have realized the production of conventional thematic maps and thematic heat maps based on spatial data. [0003] The present invention is connected to the index database of the natural resources land space planning industry (supports multi-index and multi-dimensional index data), and can also access data files conforming to index specifications, unifies the data structure required by each topic type, and provides visual style settings The interface can output the ability to independently adjust thematic effects. By deconstructing and reconstructing the standard data structure and thematic style structure on demand, the data that meets the initializati...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides templates for making nearly ten kinds of thematic maps commonly used in spatial cartography, realizes real-time display of thematic effects, opens up the index database of the land and space planning industry, and solves the difficulty in data docking and graphics in the application of multi-index, multi-dimensional, and multi-thematic expression Difficult to configure, difficult to change thematic effects, etc.
