Refining the survey model of the LADM ISO 19152–2: Land registration

Cadastral surveying involves the delineation of property boundaries and the extent and documentation of easements and restrictions (imposed by private or public law), forming the foundation for Land Administration (LA). Survey models and processes constitute vital parts of Cadastres and Land Administration Systems (LASs). However, these...

Refining the Legal Land Administration-related Aspects in LADM

Among the topics that are introduced and/ or being refined in the context of the revision of the LADM 19152:2012, the legal Land Administration-related aspects are being investigated. With the knowledge and the experience from the developments of the LADM so far, and the ongoing discussion between the parties involved in the standardisation...

Developing the refined survey model for the LADM revision supporting interoperability with LandInfra

The origin of surveying has a close connection with the designation of land boundaries, while cadastral surveying is a means of defining the limits of properties, thus forming the basis for land administration, serving as an important tool to gather, assess, and update geographical spatial data. Accurate description and record of land are the...

Methodology for the development of LADM country profiles

The growing recognition and influence of the ISO 19152:2012 Land Administration Domain Model (LADM), is revealed by the multiple country profiles that have been developed based on the standard in various jurisdictions across the world. The ongoing revision of the LADM Edition I, initiates discussions related to the development of country...

BIM/IFC files for 3D real property registration: an initial analysis

Land Administration is a quite inter-disciplinary field involving experts and knowledge regarding legal aspects, institutional support to establish relationships between involved parties and technical support to realize it. Today, land administrators and development organizations are challenged by an unprecedented demand to utilise space above...

3D land administration: A review and a future vision in the context of the spatial development lifecycle

Land Administration practices worldwide rely mainly on 2D-based systems to define legal and other spatial boundaries related to land interests. However, the built environment is increasingly becoming spatially complex. Land administrators are challenged by an unprecedented demand to utilise space above and below earth's surface. The...

Development of 3D spatial profiles to support the full lifecycle of 3D objects

Investigating 3D spatial unit's as basis for refined 3D spatial profiles in the context of LADM revision

Dense urbanisation has led to an increasing demand and pressure for land development, resulting in the partition of 3D space into different owners sharing delimited property interests on, above or below the land surface. Consequently, cadastral spatial units range from simple, but most common, 2D, to complex 3D collections of spaces worldwide,...
