ItemThe current status and ongoing investigations of 2D and 3D digital cadastre (ePlan) in Victoria, Australia(CEUR, 2017-01-01)EPlan is a collaborative program between the Australian land authorities and the surveying industry, in conjunction with the Intergovernmental Committee on Surveying and Mapping (ICSM) which aims to replace paper and PDF plans with digital files based on a national standard. ePlan was introduced in Victoria in 2011 and has been operational in this jurisdiction for 2D (non-building) plans since 2013. On average, one ePlan application is currently submitted to a digital plan lodgement portal every fortnight. The low uptake of ePlan is caused by a number of challenges which includes surveyors acceptance of adopting a new method of producing plans, the quality of the visualisation service which converts the ePlan LandXML file into PDF as the legal title diagram, and support for 3D building subdivision plans. This paper aims to explore the current status of ePlan implementation in Victoria and discuss the ongoing research programs developed to address the aforementioned challenges.

Item3D Digital Cadastre Journey in Victoria, Australia(Copernicus GmBH, 2017-10-23)Land development processes today have an increasing demand to access three-dimensional (3D) spatial information. Complex land development may need to have a 3D model and require some functions which are only possible using 3D data. Accordingly, the Intergovernmental Committee on Surveying and Mapping (ICSM), as a national body in Australia provides leadership, coordination and standards for surveying, mapping and national datasets has developed the Cadastre 2034 strategy in 2014. This strategy has a vision to develop a cadastral system that enables people to readily and confidently identify the location and extent of all rights, restrictions and responsibilities related to land and real property. In 2014, the land authority in the state of Victoria, Australia, namely Land Use Victoria (LUV), has entered the challenging area of designing and implementing a 3D digital cadastre focused on providing more efficient and effective services to the land and property industry. LUV has been following the ICSM 2034 strategy which requires developing various policies, standards, infrastructures, and tools. Over the past three years, LUV has mainly focused on investigating the technical aspect of a 3D digital cadastre. This paper provides an overview of the 3D digital cadastre investigation progress in Victoria and discusses the challenges that the team faced during this journey. It also addresses the future path to develop an integrated 3D digital cadastre in Victoria.

ItemAn LADM-based Approach for Developing and Implementing a National 3D Cadastre – A Case Study of Malaysia(FIG (International Federation of Surveyors), 2018)With the growing dominance of multi-storey buildings and other infrastructures, 2D-based cadastral systems are facing new challenges in recording, managing and visualising the spatial extent of vertically stratified cadastral spaces. In Malaysia, surveying and cadastral measurements are currently stored in the National Digital Cadastral Data Base (NDCDB), which is a 2D-based database in the form of planimetric coordinates (X, Y). However, in reality, cadastral objects are three dimensional and 2D-based approaches provide a fragmented view of these 3D spatial objects. Another challenge is that multiple pages of 2D drawings, which are used to show all the spaces of multi-storey buildings and surroundings, imposes a significant amount of cognitive effort for inexpert stakeholders who cannot easily understand the accurate location of cadastral boundaries obscured within physical structures. Therefore, the methods of data collection, calculation and adjustment of existing survey and processing data needs to be up raded for the purposes of implementing 3D cadastral database and producing 3D digital certified plans.
