BIM-LADM Amalgamation - A Review

This paper discussed two International Organization for Standardization (ISO) standards, namely, ISO 19152 – Land Administration Domain Model (LADM) and ISO 16739 – Industry Foundation Classes (IFC), to identify three-dimensional (3D) multi-floor building rights. These days, it is challenging to characterize all multifunctional structures due to...

3D Land Administration System for Wilayah Sarawak based on LADM Edition II -Preliminary Works

The numerous country profiles developed in compliance with ISO 19152:2012 Land Administration Domain Model (LADM) in different jurisdictions worldwide reflect the standard's growing significance and acceptance. A country profile may outline the current situation in the land administration (LA) domain and adapt the existing land administration...

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...

Web Visualization of 3D Strata Objects based on CityJSON and LADM

Owing to population growth in Malaysia, there have been significant stratified subsurface and aboveground developments, particularly in densely populated areas, posing a challenge to the current land administration system and the urge to constantly improve. Land Administration Domain Model (LADM) provides a relatively generic spatial...

Converting BIM Data to CityGML for 3D Cadastre Purposes

Currently, stratified property rights are registered and managed using two-dimensional subdivision plans. These plans do not accurately depict property spaces in complex structures such as high-rise buildings, tunnels and utilities, underground infrastructures, etc. 3D rich data like building information modelling (BIM) could be utilized as a...

Cross-sector transferability of metrics for air traffic controller workload

Air traffc controller workload is an important impediment to air transport growth. Several approaches exist that aim to better understand the causes for workload, and models have been derived to predict workload in new operational settings. These methods often relate workload to the diffculty, or complexity, that an average controller would have...

3D Strata Objects Registration for Malaysia within the LADM Framework

This paper discusses 3D objects registration and modelling for cadastral objects within the Land Administration Domain Model (LADM) framework. A conceptual model as well as the associated technical model for the 2D and 3D objects have been proposed and developed for Malaysia. For both private and public land, the main subdivision of land in...

Towards Malaysian LADM Country Profile for 2D and 3D Cadastral Registration System

This paper proposes a comprehensive Land Administration Domain Model (LADM, ISO 2012) country profile for 2D and 3D cadastral registration system for Malaysia. The proposed Malaysian country profile is partly based on the existing spatial (including survey) and administrative registration systems, and partly based on new developments inspired by...

Development of a Prototype for the Assessment of the Malaysian LADM Country Profile

During the last couple of years, the potential of 3D and Land Administration Domain Model (LADM, ISO 2012) based cadastral registration in Malaysiahas been investigated and described in several papers, and presented at various International Federation of Surveyor (FIG) meetings. Based on these preparations, a two day workshop and additional...

Solution Space-based Approach to Assess Sector Complexity in Air Traffic Control

Various methods have been introduced in the past in efforts to optimize airspace sector design and the allocation of air traffic controllers. This is done with the aim to accommodate growth, increase productivity and most importantly to ensure safety of air traffic. To accomplish this, a more comprehensive understanding of human workload,...

Developing 2D and 3D cadastral registration system based on LADM: Illustrated with Malaysian cases

This paper investigates several aspects of the Land Administration Domain Model (LADM, ISO 2012) associated to 2D and 3D cadastral situations within Malaysian cadastral registration system. Literature review shows that many countries propose their own profile based on the LADM such as The Netherlands, Portugal, Indonesia, Korea, Japan, Australia...

3D Modelling for Multipurpose Cadastre

Three-dimensional (3D) modelling of cadastral objects (such as legal spaces around buildings, around utility networks and other spaces) is one of the important aspects for a multipurpose cadastre (MPC). This paper describes the 3D modelling of the objects for MPC and its usage to the knowledge of 3D cadastre since more and more related agencies...

Measuring Sector Complexity: Solution Space-Based Method

Unique Identifier for 3D Cadastre Objects Registration

In Malaysia, cadastre system is carried out in two-dimensions (2D) and all cadastre have their own unique ID, called Unique Parcel Identifier (UPI). UPI is widely used in various land transaction purposes e.g. sale and purchase of land, land development, and so forth. Traditionally, cadastral registration system is a basic 2D land system. In the...

Using the Solution Space Diagram in Measuring the Effect of Sector Complexity During Merging Scenarios

When designing Air Traffic Control (ATC) sectors and procedures, traffic complexity and workload are important issues. For predicting ATC workload, metrics based on the Solution Space Diagram (SSD) have been proposed. This paper studies the effect of sector design on workload and SSD metrics. When considering the SSD in evaluation of a sector,...
