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...

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

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 Cadastres Best Practices, Chapter 3: 3D Cadastral Information Modelling

In this chapter we address various aspects of 3D Cadastral Information Modelling. Of course, this is closely related to the legal framework and initial registration as presented in the first two chapters. Cadastral data models, such as the Land Administration Domain Model, which include 3D support, have been developed for legal information...

Initial analysis of the second FIG 3D cadastres questionnaire: Status in 2014 and expectations for 2018

Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces)....

Initial Analysis of the Second FIG 3D Cadastres Questionnaire: Status in 2014 and Expectations for 2018

In this paper we present the initial analysis of the second FIG 3D Cadastres questionnaire, spanning the years 2014-2018. The first version of the 3D Cadastres questionnaire was conducted in 2010 and collected the status of 2010 and the expectations or ambitions for 2014. Most of the FIG 3D Cadastres working group members had completed the 2010...

The modelling of spatial units (parcels) in the land administration domain model (LADM)

The Land Administration Domain Model (LADM) is under development within the Technical Committee 211 (TC211) of the International Organisation for Standardization (ISO) and identified as ISO 19152. Within the LADM classical cadastral concepts as “parcel” and “boundary” have been extended to be able to include spatial representations of...

Transforming the Land Administration Domain Model (LADM) into an ISO Standard (ISO19152)

In February 2008, FIG submitted the Land Administration Domain Model (LADM) to the International Organization for Standardization (ISO). After three meetings with the LADM/ISO19152 Project Team (in Copenhagen, Denmark, May 2008; in Delft, The Netherlands, September 2008; and in Tsukuba, Japan, December 2008) we are now preparing a Committee...
