Road Network Generalization Method Constrained by Residential Areas

Residential areas and road networks have a strong geographical correlation. The development of single feature could destroy the It is necessary to establish collaborative generalization models suitable for multiple features. However, existing network methods mapping purposes do not fully consider residential areas. Compared with networks, higher priority in cartographic generalization. In this regard, study proposes method constrained by First, roads settlements obtained from clustering were classified. Next, importance was evaluated certain selected as control Subsequently, nodes built, traffic paths between adjacent searched. Finally, redundant simplified, visual continuity topological connectivity checked. data 1:50,000 used experimental data. results demonstrated that proposed preserves overall structure relative density characteristics network, well correlation
