四维地籍的建立与分析

目的 分析了四维地籍的概念与需求,提出了时空宗地的概念,探讨了时空宗地的演化过程,给出了土地的恒等、类型、收缩与扩展4种权益变换和产生、消亡、边界调整、划入、划出与复合分并6种空间演化。基于4种空间拓扑关系与13种时间拓扑关系,建立了时空宗地的时空拓扑关系。在此基础上,结合地籍相关理论与技术发展,构建了四维地籍概念模型,并依据实现策略不同,提出了标签式、混合式与完全式3种解决方案。

Establishment and Analysis of 4D Cadastre

Objective The paper analyses the concept and requirements for 4Dcadastre and proposes the spatio-temporal parcel concept.The evolutionary process of a spatio-temporal parcel is discussed and fourrights and interests transformations:identically equal,type,contraction and expansion and six spatialevolutions transformations:appearance,disappearance,boundary adjustment,union,split and re-al-location are proposed.Based on four spatial topological relationships and thirteen temporal topologicalrelationships,the spatio-temporal topological relationships of spatio-temporal parcel are established.Combining cadastral correlation theories and technical development,this paper describes a 4Dcadastre con-ceptual model which includes three solutions:tag pattern,hybrid pattern and the completely pattern.This re-search provides a theoretical reference and technical support for the establishment of 4Dcadastre.
