Abstract: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.
