A Proposal for Streamlining 3D Digital Cadastral Data Lifecycle

Abstract

In urban areas, managing the lifecycle of land and property data related to interlocked and intertwined structures and infrastructure services is a grand challenge for cadastral systems. Addressing the physical and legal complexities of vertically stratified ownership arrangements is a major step towards the modernization of cadastral systems. The research problem that this study addresses is the lack of a simplified and effective approach for modelling, storing, visualizing, and querying 3D cadastral data for multi-story buildings. This research primarily leads to the development of an approach based on Building Information Modelling (BIM), as well as state-of-the-art ETL (extract, transform, load), database and visualization technologies for 3D cadastral data lifecycle management in current practices. The proposed steps for recording, preserving, and disseminating 3D cadastral data are crucial in shifting current 2D cadastral systems towards 3D digital information systems. The results showed improvements in data creation, storage, conversion, and communication when upgrading from a 2D to 3D digital cadastre. Therefore, this study confirmed that streamlining the lifecycle of cadastral data using 3D environments would mitigate issues associated with the current fragmented 2D cadastral datasets used in the multi-story developments.

3D Cadastral Database Systems—A Systematic Literature Review

“…They used ShapeChange to create the XML file of the physical data model and exported the output into GML format [123]. In some cases, local formats like ePlan were used [15], while in others, ontology was used to combine different domains and to merge with other standards and formats. For example, Soon et al proposed a semantic-based fusion framework by extending the LADM OWL ontology to integrate CityGML and 3D LandXML [124].…”

“…The second challenge was resolved by introducing a Triangulator transformer, which splits wall geometry into triangular units, resulting in valid solid geometries in the 3D spatial database. Ultimately, the data were visualised using Cesium, and a few queries were used to verify the results [15]. This study offered a practical solution for streamlining the 3D cadastral data lifecycle, addressing data preparation, storage, management, and communication challenges.…”

“…Depending on the requirements, these data can be created and manipulated using either file-based or database storage. For example, surveyors may use files to store and lodge 3D data, whereas land registry organisations may utilise databases to register and update 3D cadastral data [15]. There are several major disadvantages associated with traditional file-based solutions, including data isolation, data redundancy, and application dependency [16].…”

Bim-Ladm Amalgamation — A Review

“…The content of RRRs can be modeled based on the LADM standard national while BIM provides rich semantic information for land management activities. Combining BIM/IFC with LADM creates a correlation that enhances our understanding of the legal space in complex building Guler et al, (2022); Ying et al, (2021); Olfat et al, (2021). BIM is increasingly applied to 3D condominium ownership management, offering advantages like semantic relationships between legal spaces and together with ownerships.…”

A Methodological Approach towards Cyber Risk Management in Land Administrations Systems

“…This geographic information provides an authoritative mapping of land parcel boundaries and associated attributes that enable land markets [12], secured land tenure [2,13], and evidence-based policymaking [14]. However, the integrity and resilience of land information infrastructure now face acute risks in an increasingly digitised and interconnected era [15][16][17][18]. The need for innovative approaches tailored specifically to managing cyber risks within LAS organisations remains unfulfilled [19].…”
