摘要
文章介绍了目前采用二维矢量地图和三维数字地球的地理信息显示软件在空间数据处理、表现方法、用户接口界面上的不足之处,提出一种面向二三维一体化的软件技术框架,通过有机组合场景内的地理空间资源、对象元数据、对象呈现模式、空间坐标关系等内容,达到在系统内统一空间对象数据模型,支持多样化的视图和图形呈现,并能够通过一体化的交互操作维护对象状态的一致性。
The geographic information display software using the two-dimensional vector map and threedimensional digital earth is introduced in this paper.Against the shortcomings of data processing,performance method,user interface,a kind of software framework for the two and three-dimensional integration is put forward.The geospatial resources,object data source,object showing style and space coordinate relationship within the scene are organically combined in order to achieve the unification of spatial object data model in the system,support multiple views and graphic rendering,and maintain the consistency of object state through interactive operation integration.
