摘　　要：针对空间数据接边入库提出了一种新的方法,可有效改善传统方法效率低和质量不可控等问题。为提高接边处待合并要素的提取效率,根据当前数据要素总数和接边线总长度进行接边线最优分段处理;同时,为满足数据入库质量要求,采用网络分析技术对数据进行优化处理,删除接边处多余节点。实践表明,本文提出的方法可以兼顾空间数据接边入库的效率和质量,在保证质量的前提下节省了人力、物力和时间,在基础测绘和地理国情普查等数据的接边入库工作中发挥了重要作用。In this paper, a new method of spatial data edge matching and storage is proposed to improve the low efficiency and uncontrollable quality of traditional methods.For increasing the extraction efficiency of elements which should be merged on both sides, the optimum segment of the matching line has been processed according to the total number of elements and the length.At the same time, in order to meet the quality requirements, the network analysis technology has been used to optimize the data and delete the redundant nodes.The practice shows that the proposed method can take the efficiency and quality of spatial data edge matching and storage into account, and save labor, expenses and time. It has played an important role in basic surveying and geography census.
