摘要
合理划分网格是进行湖泊网格化科学管理的基础。现有的湖泊网格划分一般采用手动方式,划分效率低,且由于湖泊几何形态复杂,往往会出现划分不合理、存在拓扑错误等问题。本文在确定网格分级、属地完整、属地内规则等原则的基础下,提出一种网格分割-合并的方法,实现了湖泊网格自动划分。实验表明,所提出的划分方法能合理进行湖泊网格的划分,无拓扑错误,划分的效率较高。
Reasonable grid division is the basis of scientific management of Lake grid.The existing Lake grid division is usually manual,which has low efficiency.Due to the complex geometry of the lake,there are often unreasonable division and topology errors.Based on the principles of grid classification,territorial integrity and territorial rules,a method of grid segmentation and merging is proposed to realize the automatic grid division of lakes.The experimental results show that the proposed method can divide the lake grid reasonably without topology errors and has high efficiency.
