Indoor Abstract Spaces: Linking IndoorGML and LADM

In this paper we investigate the possible synergy between two different but related standards: OGC’s IndoorGML and ISO TC211’s LADM. Both (can) deal with 3D spaces with properties, constraints and associations attached and both can operate with abstract notations of space. But there are also differences, e.g. LADM is a conceptual model, while...

Design and Development of a 3D Cadastral System Prototype based on the LADM and 3D Topology

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...
