摘要
World Wind是NASA发布的开放源码的地理软件,是提供丰富数据的数字地球平台之一。但是,如何在其已发布数据基础上,通过网络应用来扩展其数据应用,如何将用户的应用数据或其它数据提供者的数据与现有数据结合使用,是我们需要解决的问题。通过采用WebService技术进行地理信息服务和发布,使用GeoServer作为地图服务器,将OpenGIS Webservice规范和PostGIS空间数据库进行整合,通过网络空间数据扩展使WorldWind客户端与其自身的数据服务集成使用。在其平台基础上基本实现可自由扩展和发布数据供WorldWind客户端使用,实现更广泛和深入的扩展应用。
World Wind is one of the most popular digital terrestrial platforms whose technology is advanced and can provide abundant data. The utilization of the published data to expand its data application through net application and the combination of the user＇ s application data or data from other sources and the data published on WorldWind are problems that remain to be solved. With the WebService technology for publishing geographic information services, the utilization of GeoServer as a map server, and the integration of OpenGIS WebService norms and PostGIS spatial database, network spatial data expansion can be used by WorldWind clients and integrated with its data services. On the World Wind platform, spatial data expansion and publication can be dealt with freely, and a more extensive and in- depth expansion can be achieved.
