Abstract: As the skeleton of urban cities, the spatial pattern recognition of road networks is of great significance for map generalization, spatial data mining, and multi-scale representation. This paper presents an approach to recognizing the compound grid pattern of road networks with local heterogeneity based on road meshes. Firstly, the multilevel cognitive characteristics of the linear and grid pattern of road meshes are analyzed, and the multilevel cognitive order, which from basic mesh, compound mesh to regular pattern, is proposed. Secondly, the recognition methods of inclusion relationship, parallel relationship, and linear pattern between road meshes are designed considering the composability, linearity, and extensibility of compound linear pattern. Finally, the linear patterns are combined and decomposed to extract the compound grid pattern of road meshes. Experiments show that the proposed method is effective for compound grid pattern recognition with the agreements of human spatial cognitive characteristics.
