| 摘 要： | 鉴于水系自动综合中河系数据模型建立的复杂性,利用ArcObject提供的组件在双线河和狭长湖泊间构建约束的Delaunay三角网,继而提取其骨架线,从而得到双线河和狭长湖泊的中轴线,之后进行拓扑关系的保持,有效地简化了水系数据模型的建立,为后续的空间分析打下基础。 |

| Abstract: | Due to the complexity of the establishment of the river data model in the process of automatic map generation,the author established the Delaunay triangulation network between the double lines of the rivers or long and narrow lakes with the help of ArcObject,then extracted the skeleton lines which can bring up the medial axis of the double line rivers or lakes,finally kept the topological relationship between the rivers and lakes,which simplified the establishment of the river data model and laid foundations for the further spatial analysis. |
| Keywords: | river data model Delaunay triangulation network ArcObject skeleton line medial axis |
