| 摘 要： | 针对海岸线综合中以弯曲高度和弯曲深度为化简指标的不足,提出了以弯曲骨架线为指标的综合方法。在基于曲线单调段的弯曲识别的基础上,通过弯曲部位三角网的构建提取了弯曲骨架线。结合＂扩陆缩海＂原则进行了海岸线综合实验,验证了该方法在保持海岸线形态特征方面的有效性与可行性。

| Abstract: | In view of the disadvantages of the coastline generalization using the simplification index of bend height and bend depth,a new method based on the skeleton line of curve bends is introduced.Each bend is identified through the monotone curve,and the bend skeleton lines are extracted through the construction of triangulated network.Experiments based on the generation principles of unilateral coastline show the method is effective and feasible to keep the coastline shape coincident. |
