摘　　要：WebGIS是互联网环境下存储、管理、分析和发布出版空间信息数据的分布式计算机应用系统。首先,在分析WebGIS服务端的基础上,基于GeoServer对外发布离线瓦片与矢量图层地图服务;其次,设计并构建了基于OpenLayers的WebGIS客户端,客户端调用地图服务分别加载相应URL地址返回的图层影像数据进行图层叠加;最后,通过解析航空器ADSB实时位置信息数据,将航班信息通过WebSocket的方式主动推送到客户端,客户端在图层上显示实时航班动态,能直观地显示出进出机场飞行中的航班信息。此方案开发的WebGIS服务平台具有良好的可扩展性,结构层次清晰,提高了开发效率,为开源组件实现WebGIS空间应用研究提供了新的思路,可运用于智慧机场建设等领域。The WebGIS is a distributed computer application system that stores,manages,analyzes and releases spa⁃tial information data in the Internet environment.Firstly,based on the analysis of the WebGIS server,map services for offline tiles and vector layers are released based on GeoServer.Then,a WebGIS client based on OpenLayers is designed and constructed,and the client calls map services to load the layer image data returned by corresponding URL addresses for layer overlapping.Finally,by parsing the real-time location information data of the aircraft ADSB,flight information is actively pushed to the client through WebSocket,and the client displays real-time flight dynamics on the layer,which can intuitively display flight information during in-and out-of-airport flights.The WebGIS service platform developed by this scheme has good scalability and clear structural hierarchy,which improves development efficiency,and provides new ideas for open-source components to realize WebGIS spatial application research,and it can be applied in fields such as smart airport construction.
