| Abstract: | Automated matching of point features from different sources plays an important role in spatial data integration and fusion.Aiming at the problem that existing methods match homonymous features by means of strategy of finding optimal solution locally,which will cause mismatch often occurs when homonymous road features differ greatly in their locations,so in order to solve such a problem,this paper constructs global optimization model of matching road network through analyzing matching confidence of point fea... |
