A Method of Spatial Data Edge Matching and Storage

doi:10.13474/j.cnki.11-2246.2017.0094

Abstract

Abstract: 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.

Key words: spatial data, matching line, segment processing, network analysis
