An Adaptive Method for Incremental Updating of Vector Data

Year: 2016

Type: article

Abstract: To maintain data consistency and eliminate the spatial conflicts brought by spatial database updating,an adaptive method for incremental vector data updating is proposed.Based on the matching of correspondent objects,a change-object detection and incremental updating method is discussed.Considering the constraint of spatial distance,semantic similarity and topology consistency,it is proposed a calculated method for edge matching evaluation.An adaptive edge matching strategy is also designed to maintain the consistency of spatial data.The rule-based detection and manipulation of spatial conflicts is also discussed.Topographical data are used to verify the practicality and efficiency of the method.
