基于WebGIS的动态演播系统的设计与实现

Design and Implementation on Dynamic Demonstration System Based on WebGIS

针对商业化演播软件在处理与地理信息相关的演播时存在交互性有限、动态和多维展示能力不足等问题,设计了一种基于WebGIS的多源信息动态演播系统。探讨了该系统的总体框架、数据库设计和技术体系,分析了演播页面结构设计、演播编排设计、数据自动上图、地图服务构建等关键技术,并以成都到拉萨的驾驶路线演示为例,探讨了关联图层的编辑、演播工程的编辑及演播展示等技术环节。

Aiming at the problems such as limited interactivity and lack of dynamic and multi-dimensional display ability of commercial studio software when processing the studio related to geographic information,a multi-source dynamic demonstration system based on WebGIS is designed.It discusses the overall framework,database design and technical system of the system,and analyzes the key technologies such as demonstration page structure design,demonstration arrangement design,data automatic mapping and map service construction.Taking the driving route demonstration from Chengdu to Lhasa as an example,it also discusses the editing of association layer,editing of studio project and demonstration show.
