在路网结构几何形状分析的基础上，提出了一种基于模式识别的方法对城市路网中的格网结构模式进行自动识别。该方法从方向一致性、形状相似性出发对路网数据中的格网结构进行识别，并在区域增长算子的基础上对识别出的相邻的格网进行聚合。实验结果表明，该方法能够有效地对城市路网中的格网结构进行自动识别，为路网数据的匹配、多尺度表达奠定基础。

Structural patterns of road networks play a vital role in the simplification, multiple representations of road networks. This paper proposes an automated method for identifying grid-like patterns from road networks. The proposed method firstly identifies grid-like patterns according to the shape similarity, and the direction similarity of road networks.Then it clusters grid-like patterns based on a region incremental algorithm. Experiments show that the proposed method is capable of automatically identifying grid-like patterns from road networks.
