三维电子地图服务平台的关键技术研究

Research on the Key Technology of 3D Digital Map Service Platform

针对二维电子地图难以满足城市信息化管理的需求,提出建设城市三维电子地图的方法。通过三维电子地图的生产,利用ArcGIS Server和Flex Builder开发了可视化三维电子地图平台,实现城市的三维地图显示、浏览、查询功能,并能提供基于三维电子地图的地图书签服务、自驾查询服务、地图标记服务、地图纠错服务、地图广告服务等。重点阐明了系统总体技术路线、三维地图数据建设流程、服务平台构建技术等关键技术,所构建的三维电子地图服务平台在网络公众服务方面有较广阔的应用前景。

A way of the urban three-dimensional（3D） digital map was proposed in order to solve the difficulty to meet the needs of urban in- formation management. Through the production of 3D map, we developed the 3 D digital map service platform based on ArcGIS Server and Flex Builder. The platform has the function of 3D map display, browse, query, and also provides the map bookmarks service, drive the query serv- ice, map marking services, map error correction services and map advertising services. The article focused on some key technologies about the system overall technical routes, 3D digital map construt：tion processes, building technical of the service platform. The 3D digital map service platform has a broad application prospect of the web public services.
