| Abstract: | This paper discusses the history and current status of edge matching of digital map and does research on its theory,key technologies and work flows.AutoCAD data is analyzed and for edge matching characters of different objects,various matching methods are designed.Under VBA environment,by choosing different objects,classification and sorting are carried out.Then,the edge matching of different experimental objects are realized by secondary development.It shows that the realization solves the complex matching work problems and improves greatly the efficiency of map digitization and the quality of digital maps. |
