摘要
随着WebGL技术和GIS技术的发展与应用,基于网络的三维地理信息可视化技术以其立体、直观的特点,迅速成为研究热点。为了快速构建功能完备、稳定可靠的三维GIS平台,本研究首先提出一种基于Cesium等技术设计的三维WebGIS可视化方案;然后从场景构建、系统功能设计与实现两方面展开探讨,详细介绍三维可视化的相关技术和系统主要功能的实现手段;最后对三维WebGIS快速构建方法进行总结。本研究所采用的技术可靠、交互设计友好,平台设计具有较强的通用性,可为多种应用场景的三维GIS平台设计提供参考。
With the development and application of WebGL technology and GIS technology,the 3D geo⁃graphic information visualization based on web has become a hot research quickly because of its stereo⁃scopic and intuitive characteristics.In order to build a fully functional quickly,stable and reliable three-dimensional visualization platform of geographic information,a fast method to build 3D GIS platform based on WebGL was offered.Firstly,the architecture design of 3D GIS platform was introduced,and a 3D WebGIS visualization scheme based on Cesium and other technologies was proposed.Second,the 3D scene construction and system function design and implementation were discussed,and the relevant tech⁃nologies of 3D visualization and the completion methods of system interactive functions were explained.Finally,the rapid construction method of 3D WebGIS was summarized,the results show that the technol⁃ogy adopted in this paper is reliable,the interaction design is friendly,and the platform design has strong universality.The research content of this paper can provide reference for the design and construction of 3D GIS platform of various topics.
