3D Land Administration: Current Status (2022) and Expectation for the Near Future (2026) – Initial Analysis

This paper refers to the creation or update, organisation and initial analysis of the results from the 4th FIG 3D Land Administration Questionnaire, as an activity of the FIG Working Group 3D Land Administration 2022-2026.<br/><br/>The questionnaire on 3D Land Administration is conducted as a successor of the previous questionnaire on 3D...

Public Law Restrictions in the Context of 3D Land Administration—Review on Legal and Technical Approaches

Intense exploitation of land implies the development of multi-level, multi-purpose, overlap-ping and interlocking structures on 3D space, thus resulting in complex, stratified, 3D real property rights between individual owners, as well as restrictions. Legislation regulates the ownership status and use of land by imposing restrictions known...

Investigating 3D spatial units’ types 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,...

3D Cadastre and LADM – Needs and Expectations towards LADM Revision

The last decade, significant progress has been made in advancing the concept of 3D Cadastre and related technologies to facilitate its realisation. There are many examples of partial implementation and prototypes of 3D parcels registration around the world as stated by Kitsakis et al (2016) and Dimopoulou et al (2016) regarding selected...

Requirements for Standardised Representation of Public Law Restrictions based on LADM

Legal relations applying to land are of significant importance for land administration. Such relations include Rights, Restrictions and Responsibilities, deriving both from Private and Public Law. However, only the former are normally registered within cadastral systems, while the latter are either not required to be registered, or are...

A 3D LADM prototype implementation in INTERLIS

The massive developments and uses of high-rise buildings indicate that the demand for use of space above and below the ground surface is rapidly increasing in recent years. The same applies to Greece, where the existing cadastral model does not cover the 3D needs and does not conform to international standards. In this paper, a model is...

INTERLIS Language for Modelling Legal 3D Spaces and Physical 3D Objects by Including Formalized Implementable Constraints and Meaningful Code Lists

The Land Administration Domain Model (LADM) is one of the first ISO spatial domain standards, and has been proven one of the best candidates for unambiguously representing 3D Rights, Restrictions and Responsibilities. Consequently, multiple LADM-based country profile implementations have been developed since the approval of LADM as an ISO...

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...
