The Application Domain Extension (ADE) 4D Cadastral Data Model and Its Application in Turkey
LAND, 2022
The 3D cadastre, one of the most fundamental components of the 3D LAS (Land Administration System), aims to provide an integrated 3D view of legal (Right, Restrictions, and Responsibilities–RRR) and physical boundaries in multi-storey properties; therefore, to extend the flexible and modular basis of LADM, which best represents legal boundaries and RRRs, some integrated models using technical standards (e.g., CityGML, IFC, InfraGML) are developed to represent the full 3D cadastre. However, since most of the developed 3D integrated data models are designed at the conceptual level, there is a knowledge gap in logical data model relationships, which is the next processing step in the fully integrated 3D data model stage. The main argument of this study is an innovative ADE 4D Cadastral Data Model to represent 3D cadastral objects registration with time attributes using LADM and CityGML. The data management and organization are done in an open-source database for the Turkish cadastral system. This research will discuss two main topics. The first is how to implement a suitable way of realising LADM-based 3D cadastral object registration by focusing on developing the presentation of those cadastral objects to 4D (3D + t), with time attributes in alignment with the jurisdictional framework in Turkey. The second is how the data is managed in an open-source PostgreSQL database. In addition, the usage type of cadastral objects is shown in a CesiumJS, a visualisation platform. Moreover, this study will contribute to eliminating the knowledge gap between the conceptual and logical models.

Type people to land relations are dynamic and, as a consequence, the nature of land title and cadastral data is of a dynamic nature. Land title and cadastral data are core components for a lot of property applications (e.g. taxation, valuation, mortgage). Those applications require up to date, complete and reliable data-including temporal data as in use in application forms and transactions. In this paper, the modelling of Rights, Restrictions and Responsibilities (RRR) is discussed with a focus on the modelling of easement rights in a case study in Turkey. Functional requirements with respect to the characteristics of easement rights are investigated based upon interviews with professional experts in the public and private sector. Then a prototype model was built based on a simple implementation of the Land Administration Domain Model (LADM) RRR classes and by conforming to the national cadastral data management standards related to land registration systems. This new proposed model includes temporal cadastral attributes related to easements. This is materialised in the 'Administrative Package' and illustrated in the Turkey LADM country profile. We show that the LADM can be used to describe for the time dimension of cadastral information in Turkey, but that there are semantic differences, similarities and mismatches of classes and attributes between the LADM and the cadastral information system in Turkey. Proposed LADM-based model for the time dimension of cadastral information will be of immense advantage to land administrators, the governments and land users in Turkey.
Designing three dimensional property right database for Turkey
African Journal of Business Management, 2011
Current cadastral systems are two dimensional. Therefore, three dimensional (3D) property rights and restrictions cannot be registered and their legal status not fixed in these systems. The need for 3D information is increasing day by day in vertical grown up cities. The cadastre, which was used for proposing land tax at the first time, is defined as the geographical information systems (GIS) used for modelling between human and land relationships; thus, the cadastre turns into multi-layer cadastre at the present time. Consequently, 3D cadastre should be examined in GIS and integrated with querying 3D right and at least property units in geospatial database should be restricted for modelling property rights and physical objects. By the reason of missing 3D topology, current information systems do not make 3D geospatial analysis perfectly. This paper aims that some 3D queries can be made in the created database. Conceptual and logical system design was implemented with unified modelling language (UML) by using Microsoft Visio 2003 software and data types which supported ESRI ArcGIS. On the other hand, 3D models were formed by using MicroStation V8 and ArcScene 9.0 softwares.
An overview of 3D cadastre from a physical land parcel and a legal property object perspective

The physical land parcel based model of representing, storing and manipulating cadastral data, which includes two-dimensional geometry as well as the rights, restrictions and responsibilities attached to it, has largely been very successful in dealing with the present needs of land administration. The emergence of newer objects and interests on land, like, 3D titles, non parcel-based interests, interests extending beyond
Towards standardisation of Turkish cadastral system using LADM with 3D cadastre
Survey Review, 2020
Cadastre in Turkey is executed as two-dimensional (2D) and parcel-based. The third dimension (3D) on land and real estate is shown in 2D on the map with permanent rights. The use of underground spaces cannot be registered. There are various problems in the registration and mapping of real estates that are under or above these excluded places. The research was motivated by some problems that have taken place in the Turkey 3D cadastre due to the inadequate spatial information systems. For this purpose, it is aimed to design a 3D cadastre country profile that takes into account the Turkish National Spatial Data Infrastructure (TUCBS in Turkish) land registry and cadastral data model and is compatible with the Land Administration Domain Model (LADM), which is defined within ISO 19152. In this study presents a detailed overview of the Turkish legal cadastre system and a proposal for realisation based on international standards.

In land administration, spatial data manegement plays the important role of defining physical characteristics of land parcels in an accurate and discernible manner. A complementary part of spatial data infrastructure (SDI) is an effective information infrastructure that serves as the backbone of the land administration system. The paper provides a framework that supports adoption of spatial data modelling based on Land Administration Domain Model (LADM) for Turkish Land Administration System (TLAS). For this purpose, a spatial and non-spatial data model based on LADM is designed concerning the single space units subject to condominium in Turkey. The proposed data model is more comprehensive, capable of organising a wider range of spatial data, and should facilitate wider exchange of land information. The model is unique because it can support a very wide range of spatial units. Furthermore, the model was developed to help establish a national spatial data infrastructure LADM-based. To conclude, the developed model is a standardised model that could be used for local and international exchange of spatial and non-spatial data concerning land administration matters.
One of the important global issues with regard to property is the scarcity of vacant land for development. Many countries, including Malaysia, do not have enough vacant land on the ground surface to cater for rapid development. In the last couple of decades, there has been an increasing demand for property development in urban areas, resulting in the division of property ownership so that different owners can own a delimited space on, above or below ground surface. Under 3D cadastre, the 2D cadastre management of data cannot meet the real land management of the three dimension space aspect and property. It is essential to introduce the 3D cadastre of Three-Dimensional National Digital Cadastral Database (3D-NDCDB) management model. Since the individualisation of property has traditionally been concerned with the subdivision of land using on surface boundaries in the cadastral system, it is appropriate now to consider how three-dimensional situations should be handled from the legal, technical and organisational aspects, and how other countries have addressed similar issues. This paper solely concerned with the theoretical aspects of the study, particularly land, land administration system, land information system and cadastre system. It covers the definitions, history and components of each concept related to properties. It also covers and explains the theory and framework of the Malaysian Cadastre System, good governance involved in land administration and cadastre. The present 2D National Digital Cadastral Database stored information in 2D planimetric. After taking consideration the framework of LADM's core classes and the design concept of it, therefore, choosing a 2D/3D Hybrid Cadastre model since it is suitable for the current situation in Malaysia. In order to achieve the objective, some of these matters must take into consideration, i.e. (a) Method of data collection (b) Adjustment and calculation of observed data (c) The products, and (d) Changes to the format and structure of existing system. It is hoped that this study will provide a better understanding of the nature of 3D-NDCDB, besides adding new information to the available literature in the field. I envisage the main contributions of this study to the present knowledge to be in the cadastral survey and mapping, and land registration practices in the Malaysian Cadastre System from the legislative and technical viewpoints.
A New Vision on Cadastral Data Model
SUMMARY Land administration systems are evolving towards an integrated land management paradigm designed to support sustainable development. In this paradigm, land administration delivers four functionalities: land mapping, land registration, land valuation and land development, each with specific data elements, with the cadastral data model at the core. Cadastral data modelling potentially plays a key role in both data and business management in modern land administration systems. However, some modifications to existing data models could potentially improve their capacity to deliver sustainability. Firstly, the existing role of land parcels and properties as core building blocks in land administration systems can be significantly extended to make the cadastral fabric available to assist management of a wider range of rights, restrictions and responsibilities by using the concept of legal property objects: an entity defined by a law or regulation which relates to a physical space on...

: Spatial representations and ownerships of 3D properties change over time. Changes are recorded as historical data of transactions, adding the dimension of 3D spatial data into 4D data, known as Cadastre 4D. Spatial representations of 3D properties are prone to disputes when the shape and dimensions representing ownership changes do not match with the reality. This paper focuses in assessing visualizations of 4D cadastre objects applying VersionedObject class stated in the International Standard of Land Administration Domain Model (ISO 19152:2012). Based on the analysis on the current strata title ownership registration implemented in Indonesia’s land Information System (known as KKP), a model of 4D spatial data that f its to the administration system in Indonesia was developed. Visualization of 4D cadastre objects applied in this research is suited to VersionedObject class LADM and presented on the web to represent changes of 3D geometry boundaries over time. Keywords: Cadastre 3D...
