Design and development of a 3D cadastral system prototype based on the LADM and 3D topology
Ying, Shen et al.
In this paper the design and development of a prototype 3D Cadastral system will be presented. The key aspects of this system are that the model is based on Land Administration Domain Model (LADM) and that the spatial profile is based on a full 3D topological structure. The prototype development starts with profiling the LADM (selecting relevant model classes and extending the model with attributes and classes where needed). The LADM supports various options for representing spatial units (parcels); e.g. a 2D parcel or a 3D volume. 2D parcel is well-known, however, how to create and maintain 3D valid parcels is still a challenge in practice. The 3D topology structure uses the well-known primitives node (0D), edge (1D), face (2D) to construct body (3D), which represent a spatial occupation of 3D parcel. Geometry is only explicitly stored at the nodes.
