| Abstract: | By summing up the research of road selection it analyzes the indicators of road elements selection during road generalization based updating, and provides the method of a road selection which refers to the road length, degree, mesh area, regional road density, geometry information, semantic information and topological information such as whether it being hanging chain, simulating human process of thinking during generalization based updating, realizing road automatic selection and the experimental effectiveness. |
