Geometry Matching Method for Transportation Road Network Data Based on Projection

  • This paper puts forward a geometry matching method for transportation road network data based on projection.Characteristic points can be extracted from lines by projection and segmentation,so complex matching of road networks is converted into a characteristic point matching problem.An incremental matching strategy was designed,that narrows the range of matching and improves matching efficiency.A proper matching threshold can not only reduce leakage match and mismatch but also improves matching accuracy.Experimental results show that this method can obtain ahigher correct matching rate that meets application requirements.
