Many immigrants from rural areas pour into urban areas, especially in China, and urban development faces the challenges to provide sufficient space for citizens’ acommodation, works and social contacts. So 3D development and use of land and city space become the reality with various complex buildings and constructions with modern architecture and construction techniques. Many underground constructions like mall and subway with stations are built without clear impression comparing to the above reality scenes. Also many buildings above the earth surface show their special characters with either air building / overpass / viadust or “strange” shapes getting our attentions; but actually they bring new challenges of spatial management to handle the 3D property unit, either in describing their relations with reference to earth surface or in performing administrative processes in transactions of planning, approval and management. From the real cases of buildings or 3D property, this paper first details the relations between 3D properties and earth surface, the relative location relations between 3D building properties and earth surface form, and the correspondence between 3D building properties and surface parcel, then classifies the category according to these three profiles, which would promote the understandings of complex buildings and 3D building properties and would enhance the descriptions and the segmentation of 3D building properties.
