摘　　要：为实现大规模矢量电子航道图(electronic nautical chart,ENC)的Web应用,基于开源的GeoServer地图服务器和前端OpenLayers地图API,提出ENC矢量瓦片技术方案,包括ENC数据处理、矢量瓦片的生成发布、矢量瓦片的访问和绘制、显示样式的切换、基于矢量瓦片的查询和空间分析应用等。方案在湖南Web ENC综合应用系统中进行验证和测试,充分利用矢量瓦片的高分辨率、实时渲染、可交互等特性,实现整个湖南水系矢量ENC数据在Web页面上的灵活显示和应用。应用案例表明矢量瓦片技术具有很好的实际应用价值。In order to implement the Web application of large-scale vector electronic nautical charts(ENC),based on the open source GeoServer(a map server)and OpenLayers(a map client API),a vector tile technical solution of ENC is proposed,including ENC data processing,vector tile generation and publishing,vector tile accessing and drawing,display mode switching,vector tile-based query and spatial analysis application.The solution has been verified and tested in the Hunan Web ENC comprehensive application system.With advantages of high-resolution,real-time rendering and interactivity of vector tile,the flexible display and application of the vecter ENC data of the whole Hunan water region in Web browsers is implemented by the solution.The application case shows that the vector tile technology has good practical application value.
