提出了一种新的海岸线（多边形和折线）逼近方法。该算法不同于通常使用的Douglas-Peucker型算法，因为该方法可以近似于给定的约束，即边长必须满足一些最小边长标准的一些特征误差。这种约束是必要的海岸线近似是有用的非结构化网格生成海洋建模。此外，该方法应用局部优化迭代地改善海岸线近似。介绍了该方法的应用。(c)2006爱思唯尔有限公司保留所有权利。
A new method for approximating shorelines (polygons and polylines) is presented. The algorithm differs from the commonly used Douglas-Peucker type algorithms as the method can approximate to some feature error given the constraint that edge-lengths must satisfy some minimum-edge-length criteria. This constraint is necessary for the shoreline approximation to be useful for unstructured mesh generation for ocean modelling. In addition the method applies local optimisations to iteratively improve the shoreline approximation. Applications of the method are presented. (c) 2006 Elsevier Ltd. All rights reserved.
