Modelling 3D underground legal spaces in 3D Land Administration Systems

Two dimensional (2D) Land Administration Systems (LASs) do not adequately represent 3D underground objects. It is not easy to identify the owners of these objects and the relations between objects below and above the surface are not explicitly provided. A 3D LAS can however facilitate a better understanding, as well as a more efficient...

Can Data from BIMs be Used as Input for a 3D Cadastre?

Much work has already been done on how a 3D Cadastre should best be developed. An inclusive information model, the Land Administration Model (LADM ISO 19152) has been developed to provide an international framework for how this can best be done. While this generic framework encompasses a wide range of eventualities, it does not prescribe the...
