已经提出了许多用于线概括的解决方案。然而，其中大多数是几何解决方案，而不是制图解决方案。我们在本文中采取的立场是观察标准制图书籍中可用的学校案例解决方案，并尝试自动复制这些解决方案。指导制图综合过程的一个中心标准是线结构，它本身可以分解为一系列的线弯曲。因此，我们的解决方案是保留整体结构与线弯曲，这是数学定义的大小，形状和上下文。随后使用诸如消除、组合和夸大之类的运算符来应用规则。所使用的算法是基于程序和知识的。在物理和政治地理线上进行了各种实验，我们展示了图形结果，以便读者可以直观地评估它们。进一步的研究，以改善目前的解决方案进行了讨论，特别是避免冲突的选项。
Many solutions for line generalizations have already been proposed. Most of them, however, are geometric solutions, not cartographic ones. The position we take in this paper is to observe school-case solutions available in standard cartographic books and try to replicate those automatically. A central criterion guiding the process of cartographic generalization is line structure, which itself can be decomposed into a series of line bends. Hence our solution is to preserve the overall structure with line bends which are mathematically defined according to size, shape, and context. Rules are subsequently applied using operators such as elimination, combination, and exaggeration. The algorithms that were used are both procedural and knowledge based. Various experiments were conducted on physical and political geographic lines, and we show the graphical results so that readers may visually assess them. Further research to improve the present solutions is discussed, particularly options for avoiding conflicts ...
