Research on vector road data matching method based on flat curve

Abstract

In this research, a vector road data matching approach exclusively targeted at road data is proposed to suit the needs of quick and real-time updates of geographic databases. The location and kind of alterations to the road construction have to be precisely identified using this method. We suggest a technique for feature matching of vector road data from several eras under the same scale and geographic coordinate system by using the properties of road alignments. This helps us track changes in road development by allowing us to recognize how different road sections vary over time. Moreover, it forms the foundation for gradual updates of spatial data.
