论文摘要
简化是地球信息科学（GIS）中使用的基本操作之一，可降低几何对象的大小或表示复杂性。尽管可以根据人的目的应用不同的简化方法，但是许多应用程序采用的简化旨在在简化后保留其空间属性。本文介绍了2D简化方法之一，尤其是在建筑物和室内空间的2D足迹等人造结构上很好地工作。该方法以迭代方式简化了多边形。简化在细分方面，并考虑到2D结构的入侵，挤压，偏移和角部分保留其主要框架。
Simplification is one of the fundamental operations used in geoinformation science (GIS) to reduce size or representation complexity of geometric objects. Although different simplification methods can be applied depending on one's purpose, a simplification that many applications employ is designed to preserve their spatial properties after simplification. This article addresses one of the 2D simplification methods, especially working well on human-made structures such as 2D footprints of buildings and indoor spaces. The method simplifies polygons in an iterative manner. The simplification is segment-wise and takes account of intrusion, extrusion, offset, and corner portions of 2D structures preserving its dominant frame.
