基于开源WebGIS的3D校园公共服务平台建设研究

A Campus Service Platform Relative to Three Dimensional Map Based on Open Source WebGIS

为探索建设一种低成本、强交互的三维校园公共服务平台,基于开源WebGIS提出了一种3D校园公共服务平台建设方案,并以南通大学为例。首先利用HTML5搭建了平台前端框架,然后通过开源Web图形库Three.js加载和渲染了三维模型,使用Ajax和Serlvet实现了网页和服务器的交互操作,最后利用Spring开发了平台后端功能。该平台的构建解决了传统三维可视化平台存在的三维模型加载慢,服务器返回数据的时间长,用户的交互体验差等问题。可为基于WebGIS的三维应用提供技术支撑,并为以地图为载体的网络3D模型的行业应用(如数字城市、智慧旅游、房产开发等)提供方案参考。

In order to explore the construction of a low-cost and strong interaction 3 D campus public service platform, this paper proposes a scheme of building 3 D campus public service platform based on the open source WebGIS,and takes Nantong University as an example. The research first built a platform framework using HTML5,then loaded and rendered a 3 D model relying on the open source web graphics library three.js, and used the Ajax and Serlvet to implement the interactive operation of the web pages and the server, finally, applied the spring framework to develop the back-end functions. The construction of the platform solves the problems of slower loading of 3 D models, longer time for server to return data, and poor user interaction experience in traditional 3 D visualization platforms. This research can provide technical support for 3 D applications based on WebGIS,and provide a reference for industrial applications(e.g. digital cities, smart tourism, real estate development, etc.) of 3 D models based on maps.
