基于地球引擎Cesium的三维WebGIS系统设计与实现

Design and Implementation of 3D WebGIS System Based on Earth Engine Cesium

随着互联网技术、3D仿真技术、智慧城市的进步,传统的地理信息技术被注入了新的活力,在互联网上传输的3D GIS正朝着数字化、智能化方向发展。3D实景模型建模速度快、成本低,已被广泛应用于城市规划、反恐、文物保护、应急预案模拟等领域。本文基于Cesium框架,设计并实现了一个3D WebGIS原型系统,用户可以通过该系统浏览3D场景、查询3D模型、解析缓冲区,无需下载插件即可直接访问系统,降低了系统使用门槛,提高了共享性和便捷性。

With the progress of Internet technology,3D simulation technology and smart city,the traditional geo-graphic information technology has been injected with new vitality,and the 3D GIS transmitted on the Internet is developing in the direction of digitalization and intelligence.3D real model is fast in modeling and low in cost,and has been widely used in urban planning,anti-terrorism,cultural relics protection,emergency plan simulation and other fields.Based on the Cesium framework,this paper designs and implements a 3D WebGIS prototype system,through which users can browse 3D scenes,query 3D models,and parse buffers.Users can directly access the system without downloading plug-ins,which reduces the threshold of system use and improves sharing and convenience.
