Abstract: 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.
