Abstract

With the rapid growth of urban environments including the increasing complexity of infrastructures, there is an urgent need to develop more innovative and efficient land administration systems. Many countries, including Australia, are now developing and implementing three dimensional (3D) cadastral frameworks to address these situations, but capturing and registering these rights within existing systems brings considerable challenges. In Australia, the existing approach of registering 3D rights and storing partial geometry in databases does not support 3D functionalities such as 3D validation, query, visualisation, and manipulation. The existing Digital Cadastral Data Base (DCDB) does not support the storage of 3D data. There is also no digital lodgement of 3D cadastral, and no automated validation (Karki, 2013).

The Intergovernmental Committee of Surveying and Mapping (ICSM) has endorsed LandXML as the national standard for digital lodgement of cadastral plans. LandXML is an extensible mark-up language (XML) package which can be used for exchanging spatial information. In Queensland Surveying information is captured digitally using tools built in-house, such as the Surveying Information Processing (SIP) tool which is based on LandXML and is used to electronically capture a paper based cadastral plans. The Electronic Access for Registry Lodgement (eSurvey, previously called EARL) project is developed and run by the Department of Natural Resources and Mines (DNRM) and it has three stages namely eSurvey-I, eSurvey-II, and eSurvey-III. The eSurvey Services Portal allows users to submit, validate and visualise survey data via Web Services.

eSurvey-I developed a tool for internal DNRM use to digitally capture the information on a survey plan. eSurvey-II has developed a validation tool that will be applied to Cadastral Information Files (CIFs) that are submitted to the Department by external surveyors as a component of the digital lodgement of survey plans process. eSurvey-III will be the full digital lodgement and implementation of electronic capture and visualisation of 3D cadastral data where the digital files become the legal document.

The objective of this research is to explore the capability of LandXML for the definition of 3D spatial objects within the eSurvey project for 3D Cadastre development in Queensland. An overview of 3D Cadastre and characteristics of eSurvey, volumetric plans and LandXML were reviewed. Two representative cases from Queensland digital cadastral database were selected and examined using three standard CAD software and eSurvey web portal and Queensland DCDB standards. This study shows that eSurvey can successfully validate LandXML files.
