This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。

Placement of late-span value is still an opportunity in the area in large numbers are more optimistic about the first 015 out cross-4,5,6,7,8, 2,3 cross-trumpet area to consider doing less, No. 016 concerns 4, 6,7,8,9 cross-out, rule out the possibility of three cross-value occurs, the first 017 candidates span the value of cross-3,5,6,7,9, 4,8 even cross there is little hope.

后期跨度值仍落点于中大数区的机会较多，第015期看好4、5、6、7、8跨开出，小号区2、3跨少做考虑，第016期关注4、6、7、8、9跨开出，排除3跨值出现的可能，第017期候选跨度值为3、5、6、7、9跨，偶数4、8跨出现希望不大。
