Abstract:

Identifying homonymous elements is the key techniques to the integration,updating and fusion of spatial data.For the problems of linear feature with the same topology but different data structure,this paper proposes a matching method of linear feature based on node similarity.This method takes the node as the main feature,selects direction and distance similarity measure criteria,and constructs three kinds of constraints,such as topology,direction and distance.On this basis,a model of similarity matching is established based on topology and spatial location,and the similarity matching of characteristic points of linear feature is realized.Experiments are carried out on a large scale road network.The experiment results show that this method is feasible and can effectively deal with the matching problem of complex linear feature.

Key words: node similarity, topology, spatial location, linear feature, similarity matching
