Study on Adjacent Nodes Inspection Based on Buffer Fusion Method

临近节点是影响矢量数据质量的关键问题。本文针对数据维度提升带来的高维信息这一特征,将要素节点升级为节点缓冲区,设计实现了基于要素节点缓冲区融合的临近节点检查方法,通过多源数据合并、要素转节点、相同节点融合、缓冲以及缓冲区融合等步骤获得要素节点缓冲区融合面,最后通过面积容差判定出临近节点所在范围。实验证明,算法通用性强,准确度高,效率稳定,定位准确,是一种有效的多源矢量数据临近节点检查方法。

The adjacent node is the key problem that affects the quality of vector data.Aiming at the characterisitcs of high dimensional information brought by data dimension promotion,the feature node is upgraded to node buffer,and the adjacent node inspection method based on feature node buffer fusion is designed and implemented.The feature node buffer fusion surface is obtained through the steps of multisource data merging,feature to node,same node fusion,buffer and buffer fusion,and finally the range of adjacent nodes is determined through area tolerance.Experiments show that the algorithm has strong universality,high accuracy,stable efficiency and accurate positioning.It is an effective method for detecting adjacent nodes of multisource vector data.
