| 摘 要： | 按照简单地块的8种拓扑关系分类定义,计算简单地块的拓扑关系。将复合地块的外边界与空洞分离为m＋1个（m是空洞数）简单多边形,分别计算外边界之间、空洞之间、外边界与空洞之间的拓扑关系,并且按照不同的拓扑关系组合,计算复合地块的8种拓扑关系。

| Abstract: | A topological relationship calculation method for complex cadastral parcel is detailed.The topological relationships of simple cadastral parcels where calculated according to the eight definitions for topological relationships classification.The outer boundary and holes in the complex cadastral parcel were then separated into m＋1（m is the number of the hole） simple polygons.The topological relationships between the outer boundaries,the holes and that between the outer boundaries and the holes where calculated by using the topological relationship classification rules for simple cadastral parcels.The eight topological relationships of the complex cadastral parcelwhere calculated by the different combinations of the topological relations. |
