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...

Formalizing Implementable Constraints in the INTERLIS Language for Modelling Legal 3D RRR Spaces and 3D Physical Objects

Building Information Models (e.g. BIM, IFC) and virtual 3D city models (e.g. CityGML) are revolutionising the way we manage information about cities. The main focus of such models is on the physical and functional characteristics of urban structures (Aien et al, 2015). On the other hand cadastral data models, (e.g. Land Administration Domain...

Systematic analysis of Functionalities for the Israeli 3D Cadastre

Following public demand to improve the efficiency and transparency of government administrations, together with the existence of mature technologies and modern urban planning necessities, it is now essential to establish more advanced and comprehensive land management (cadastre) systems. Cadastre systems available today are mostly based on...

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...

Topographic Signs: Important Context for a 3D Cadastre

Utilities, buildings and infrastructure digital representations are very important set of spatial data for quality and sustainable spatial management and development of community in general. Many countries are on the way of the establishment of the 3D cadastre. Existing 2D cadastral systems are able to make gradual transition to 3D cadastre, but...
