Towards integration of 3D legal and physical objects in cadastral data models.

Highlights: [•] Current cadastral data models are not sufficiently supporting the requirements of 3D cadastres. [•] 3D physical objects as well as 3D legal objects are important in 3D cadastres. [•] We proposed 3DCDM model as a 3D cadastral data model to improve the current cadastral data models. [•] The 3DCDM model has two hierarchies, legal and physical, which are linked in the model.
