摘要
地籍信息系统的宗地合并操作时常会失效,其原因是实际测量的宗地图形与系统要求的理想化宗地图形有一定的差异。本文针对该问题,讨论了公共点的匹配与公共边的匹配,构造了顾及误差的宗地合并算法。该算法在地籍信息系统GBland中得到应用,应用结果表明了该算法的有效性。
Sometimes the operation of merging parcel in cadastral information systems may become invalidation,since there are some gaps between surveyed parcel graph and idealization graph.To solve these problems,the common point matching and the common side matching are discussed in this paper,the parcel merging algorithm considering error is created,and it is being used by GBland cadastral system.The application result has indicated that this algorithm is valid.
