Piloting 3D Cadastre in Singapore
Defu Wu, Kean Huat Soon, Victor Khoo
Since 2000 various initiatives have been carried out to modernise Singapore’s digital cadastral survey system by the Singapore Land Authority (SLA). The initiatives include the implementations of coordinated cadastre (2004) and electronic submission (2005), establishment of Singapore CORS network (SiReNT) (2006), and digital cadastre through the implementation of Cadastral Survey Management System (CSMS) (2018). CSMS introduced new digital workflow for land-based cadastral survey submissions and a digital format called SG LandXML, which allows for automated pre-validation against Singapore’s cadastral survey rules, to improve the overall productivity. Though SLA has proposed a preliminary roadmap in 3 phases (i.e, feasibility study, pilots and implementation) (Khoo, 2011), and developed CSMS to support digital cadastre (Soon, et. al, 2016), the digitalization for strata survey was excluded in the initial implementation of CSMS.
With the advancement of Building Information Modelling (BIM) technologies, the Architecture, Engineering and Construction (AEC) industry in Singapore has geared towards the adoption of BIM. The submissions in BIM for regulatory building works have been implemented with the launch of CORENT X, a Whole of Government (WoG) submission platform in Singapore in December 2023. This has led to a new digital 3D era in AEC industry and impacted the land surveying industry to investigate the development of 3D digital cadastral submissions, especially for 3D strata survey submission. Consequently as authority for property ownerships, SLA embarked on pilots to implement 3D cadastre.
3D cadastre eco-system is comprehensive and has been studying by domain experts globally. After reviewing the latest 3D cadastre development by domain experts and researchers, SLA decides to focus on 4 core areas, which are 1) digital 3D cadastre survey techniques and workflows; 2) 3D data model and modelling methodologies; 3) regulatory validation and visualization for 3D submission; and 4) legislation and institutions framework. Presently, SLA is piloting the works in the first 3 areas which are more technical in nature.
This paper will introduce the works of the pilots, as well as the corresponding findings.
