传统二维GIS具有强大的空间查询、分析功能,而三维GIS具有很好的空间直观显示性。实现二三维GIS的联动与互操作,可以充分发挥二三维GIS各自的优点。本文提出了一种有效可行的解决方案,实现了具有实时联动漫游、缩放和信息标注等功能的WebGIS二三维联动系统。 更多还原
【Abstract】 Traditional two-dimension(2D) GIS has powerful function of spatial query and spatial analysis,while three-dimension(3D) GIS has outstanding performance of the spatially explicit visualization.The combination and interoperability between 2D GIS and 3D GIS can give full play of their respective advantages.In this paper,an effective and feasible design resolution is introduced,and a 2D/3D combined WebGIS application with real-time associated roaming,zooming,and symbol plotting has been realized. 更多还原
