Abstract: In view of the traditional land management mode based on cadastral and cannot well meet the increasingly tense demand of urban space management, this paper first analyzes the research status of 3D cadastre at home and abroad, and puts forward the technical route to solve the difficulties and pain points of three-dimensional land management based on 3D cadastral mapping. Then, based on this research content to conduct the exploration of 3D cadastral standardization, this paper mainly introduces the compilation process and main content for Technical Regulation of 3D Cadastre & Pproperty Unit Surveying and Mapping, and the research route and the standardare applied to the typical cases, so as to prove the feasibility of the technical route and the applicability of the standard.

Key words: 3D cadastre, 3D property unit, surveying and mapping, standardization
