Abstract. This paper summarises the comparison of Turkish and Malaysian cadastral registration systems based on the Land Administration Domain Model (LADM, ISO 2012) associated with 2D and 3D cadastral situations. Literature review shows that many countries propose their profile based on the LADM, such as The Netherlands, Australia/ Queensland, China, Greece and others. Turkey and Malaysia are some of the potential candidates for the LADM based country profile, as described in this paper. The study presents a detailed overview of the Turkish and Malaysian cadastral system, and LADM-based country profiles developed by the two countries are compared thanks to the common ontology offered by LADM.

Abstract. A new version of the Land Administration Domain Model (LADM) has been discussed and is under further development in ISO/TC 211 on Geographic Information. One of the extending parts is where the model can accommodate complex and advanced marine properties and cadastral objects. Currently, the fundamentals part of this new version (LADM Edition II) has been examined by the committee, and a few elements need to be considered, especially for marine space georegulation. Based on the possibility of embedding LADM with marine cadastre as agreed by several researchers, the concept of marine cadastre data model within land administration context has been anticipated in many countries (e.g., Canada, Greece, Turkey, Australia, and Malaysia). Part of the research focused on constructing and developing the appropriate data models to manage marine spaces and resources most effectively. Several studies have attempted to establish a conceptual model for marine cadastre in Malaysia. However, there is still no acceptable marine data model. Thus, this paper proposed a marine data model for Malaysia based on the international standard, LADM. The approach, by definition, can be applied to the marine environment in terms of controlling and modelling a variety of rights, responsibilities, and restrictions. The Unified Modelling Language (UML) application was utilized to construct the conceptual and technical models via Enterprise Architect as part of the validation process. The data model was constructed within the marine's concept in Malaysia to meet international standards. The features of the data model were also discussed in the FIG workshop (9th LADM International Workshop 2021). The experiment on the data model also includes 3D visualization and simple query.

Abstract. Three-dimensional visualization of 3D parcels have been investigated in many viewpoints in order to fulfil the demands of expanding cities and the increasing complexity of building design. In Malaysia, with the growing strata developed area, particularly residential buildings (i.e., apartments), land administration agencies will need to improve their application in sharing and disseminating cadastral data. Hence, web-based solutions have been recognized as an important visualization requirement among end-users. It acts as a distributed information platform that allows 3D data sharing with the minimal architecture of client-server connects by the internet. There are two key topics addressed in this paper, which is the depiction of 3D strata objects on the web and the linkage to their legal data. This paper also describes the implementation of conceptual model of strata object based on Malaysian Land Administration Domain Model (LADM) Country Profile for the representation of spatial and non-spatial data. Tools such as PostgreSQL with PostGIS extension is used for storing data, CesiumJS was used to handle and visualise 3D strata objects in a 3D browser that was customised as a web application. The results demonstrate a viewer of a multi-storey buildings using web visualization to display both physical and legal information of 3D Strata objects based on LADM country profile (Malaysia). This particular paper also attempts to address 3D visualization of spatial and non-spatial data query using a web application, which also suggests further directions for 3D cadastral visualization development.

Abstract. This paper discusses the capabilities of cadastre augmented reality (AR) and three-dimensional (3D) visualization in enhancing the stratified property visibility and information of the current strata plan in Malaysia. Currently, 2D information representation from the 2D+1D cadastre system is seen to be insufficient in serving real land management of the 3D aspect and property. Hence, toward a better digital 3D strata/property registration and land administration system in Malaysia, this study has explored the process in utilizing AR and 3D model to the current strata plan to enhance digital strata information contents and enabling the virtual strata plan presentation. The software used to develop the AR application smartphone was Unity3D software while Autodesk Revit applied to develop the 3D model and preparation of strata information. The interesting findings has been shown in this study. First result showed 3D models and strata parcel’s attribute that has been developed for AR digital content preparation. Secondly, this 3D-AR processes can continuously gather of user’s ambient information, conduct real-world recognition, and obtain real-world perception through smartphone device. Lastly, with utilization of AR technology in strata, it provides a more information to the strata plan without needing to change the current format of strata plan as the information are being displayed virtually onto the reality. With the integration of augmented reality and 3D visualization, the documentation of stratified properties in strata plan is potential to be enhanced from 2D planimetric to 3D representation. overlaid 3D model of the stratified property and standard strata information virtually on the present strata plan which has created an enhanced reality. This can allow the information to be viewed by more stakeholders with less restriction by using smartphone device.

Intense exploitation of land implies the development of multi-level, multi-purpose, overlapping 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 as Public Law Restrictions (PLRs). PLRs extend to various fields and various legislative frameworks, such as the protection of archaeological sites, protection and maintenance of underground infrastructures and utilities, environmental protection, flying of unmanned air vehicles, etc. PLRs are usually investigated in the context of property rights and restrictions in the various Land Administration Systems worldwide, and do not often gain specific attention. However, it is noticed that the restrictions that arise from Public Law need to be investigated and classified, so that they can be better utilised in the property status of land ownership. This review paper investigates the legal statutes on PLRs within the context of 3D land administration and the stipulations used to provide unambiguous modelling of PLRs, as provided by the relative literature. Moreover, the PLRs applied in the 3D space, to clearly depict rights, restrictions and responsibilities on the relevant spatial unit (land, air, marine parcel, mine, utility network, etc.), are particularly examined. Therefore, this work is to critically review and assess the aforementioned approaches on PLRs’ registration, modelling and organisation, as provided by a literature survey, and provides an overall view of the requirements and challenges within the development of 3D Land Administration Systems also considering standardisation developments.

Proving ownership of the land should preferably be done with a legal document that proves it decisively. Many authorities retain various documents, any of which could be used to assert a claim on the land. To prevent document falsification, the land administration mechanism ought to be robust, accessible at all times, and quick to accomplish exercises. But, any such solutions are prone to a slew of issues, including data accuracy, security, and dispute resolution. Usage of blockchain technology in land administration is considerably advanced to solve issues that plague current LAS. With the adoption of blockchain, the problem of cooperation among a variety of land records is articulated. The proposed model has integrated units to digitally sign the land assets to store securely into the blockchain using cryptography algorithms after which land assets are verified. The proposed approach eliminates deception, improves administration. The results show that the time complexity for registering, signing, and verifying land facts to establish a system using blockchain is relatively secure.
