Methodology of feature change detection and matching in data updating
Zhongliang Fu · Journal of Computer Applications · 2008
In the case of lack of correlation between identical entities in feature classes,the identical entity for the current feature and their change information was automatically identified by spatial analysis.When searching candidate matching collection for the current feature,a spatial query based on self-definition spatial topological relationship was designed,which narrowed the search scope,reduced the query time,and increased spatial analysis efficiency.When confirming the identical entity for the current feature,a weight-based similarity computing model was presented,and this effectively matched features in the circumstances of complex spatial relationships and improved the accuracy of matching.
