摘要
三调路面范围的几何图形主要通过地类图斑中的公路用地和城镇村道路用地得到,而公路用地和城镇村道路用地在被河流等水域穿越时不连通,从而导致路面范围不连续,给数据处理带来诸多不便。针对该情况,设计了一种基于Model Builder的路面范围连通方法。该方法根据地类图斑中公路等交通运输用地与河流等水域之间的空间关系,实现了公路等交通运输用地在被河流等水域打断处的自动连通。通过该方法构建的模型已被应用于西藏自治区三调路面范围的处理中,取得了较好效果。
The geometric figure of the road scope inherits the land used for highways and the land for roads in towns and villages, but there is a situation that the land used for highways and the land used for roads in towns and villages being passed through by the surface of the water. Aiming at this situation, we designed a connecting method of the road scope based on Model Builder. The principle of this method was the spatial relation between the land used for highways and water area. This method has a very good effect in the processing of the road scope in the third national land survey of Tibet Autonomous Region.
