特殊形态的建筑群是城市聚落区常见的布局形式，应慎重推广。类型化被认为是一种适当的操作符，用于概括具有网格模式的建筑群。类型化作为构建概化的重要算子，其目的是在尽可能地保持原有分布特征的同时，减少对象的数量。本研究提出了一种基于网格的建筑格构化方法。首先，通过考虑网格的完备性，将模式细分为完全网格或网格状模式。该方法包括三个步骤：(1)从建筑物的邻近图生成网格；(2)消除三角网格；(3)利用相关网格确定新创建的建筑物的数目、位置和表示。该方法被建模为一个迭代过程，以获得层次化的类型化结果，从而为地图的多重表示提供支持。实验结果表明，基于网格的类型化方法在网格图案和网格状图案上都能取得令人满意的效果。典型建筑的新布局保留了原有的格局特征。
Building groups with special patterns are common layouts in urban settlement areas, which should be carefully generalized. Typification is considered as an appropriate operator to generalize building groups with grid patterns. As an important operator in building generalization, the purpose of typification is to reduce the number of objects while preserving the original distribution characteristics as much as possible. This study proposes a mesh-based method to typify buildings with grid patterns. Firstly, the pattern is subdivided into perfect grid or grid-like patterns by considering the completeness of the grids. The proposed typification method consists of three steps: (1) generating mesh from the proximity graph of buildings; (2) eliminating triangular meshes; (3) determining the number, positions, and representations of the newly created buildings with the help of the related meshes. The proposed method is modeled as an iterative process to achieve hierarchical typification results, which provides support to the map multiple representation. The experimental results demonstrate that the mesh-based typification method can achieve satisfying results in the perfect grid pattern, as well as the grid-like pattern. The new distribution of the typified buildings preserves the original pattern characteristics.
