WebGL-based three-dimensional visual display system and data visualization method

Abstract

The embodiment of the invention provides a WebGL-based three-dimensional visual display system and a data visualization method. The WebGL-based three-dimensional visual display system comprises a dataprocessing and tool module, a 3DGIS engine module and a visualization engine module; the 3DGIS engine module is used for acquiring geographic space data and generating a 3DGIS map based on the geographic space data; and the visualization engine module is used for acquiring a 3DGIS map, charts and various statistical analysis numerical parameter information, fusing the charts and the various statistical analysis numerical parameter information by taking the 3DGIS map as a base map, superposing the charts and the various statistical analysis numerical parameter information on the base map, andperforming visualization display in a three-dimensional form. According to the invention, a three-dimensional GIS visualization system is achieved, and a set of effective solution is provided for related applications.

Description

technical field [0001] The present invention relates to the technical field of big data analysis, in particular to a three-dimensional visualization display system and data visualization method based on WebGL. Background technique [0002] With the rapid development of current information technology, data information in various industries has changed from single to multi-dimensional. Especially in the era of big data, massive data contains complex multi-dimensional information, and the visualization of multi-dimensional information is usually realized by converting data into easy-to-understand two-dimensional or three-dimensional graphics. However, the traditional statistical method of a single two-dimensional graph is difficult to meet the actual needs, and users cannot intuitively obtain accurate cognition of multi-dimensional information. Therefore, the 3D visualization technology that can display more dimensional information through layer overlay has attracted extensive...

Problems solved by technology

Traditional Web3D technology has the following disadvantages: (1) Need to install browser plug-ins or introduce third-party components

(2) Poor platform compatibility and low development efficiency

(3) Does not support hardware acceleration, making it difficult to render large-scale and complex 3D scenes

At present, many software suppliers at home and abroad have already begun to deploy 3D GIS, and there are a large number of products with rich functions, but they are not enough in terms of industry application depth and scalability
