Validity of mixed 2D and 3D cadastral parcels in the land administration domain model
Thompson, Rodney James & Peter van Oosterom
The Land Administration Domain Model (ISO 19152) (ISO-TC211 2012) defines a specific geometry form which allows the clean and simple mixing of 3D cadastral objects such as volumetric parcels with the more common 2D parcels. It does this by introducing a concept of boundary surfaces, known as face stringss. The unbounded nature in the vertical direction of the face stringss corresponds to the unbounded nature of 2D parcels, that is, they comprise the boundaries of infinite 3D columns of space (see ISO-TC211 2012 Figure B.2 Page 48). This, in combination with the more usual finite facee used to define a completely bounded 3D parcel, allows a highly efficient storage structure, without sacrificing the rigour of the definitions (while remaining compatible with the vast amount of existing 2D cadastral data).
