| 摘 要： | 在逐点插值算法中综合考虑了角度和距离的影响，改进了该算法中权函数的确定方法，并对水动力学数值模拟中普遍关心的边界进行了处理。进一步采取分区域选点法，用加权平均法生成了网格数字地形，实现了地形的可视化。开发了相应软件模块，并集成到已有的波浪、潮流数值模拟软件中，应用于实际工程中，取得了很好的效果。

| Abstract: | In this paper, considering the angle and distance of affection to interpolation, we improve on the weighted function in the point-by-point interpolation. Boundary between water and land is partitioned, which is well concerned in hydrodynamic. Grid digital terrain is produced with getting reference point by subarea and weighted averaging method, and is visualized. We exploit the soft and apply to wave and tide project, and proleptic result is obtained. |
