Electronic Lodgement and Transfer of Survey
Data Working Group
The ICSM ePlan Model
A Unified Modelling Language (UML) model was created and has evolved, showing the various LandXML (Land Extensible Markup Language) elements pertaining to a survey plan and their relationship with each other. It also holds detailed descriptions of each element and its attributes. The latest version of the Plan (May 2007) is available here.
Associated with this Plan is its LandXML schema. The latest version of the schema (Version 1.1) is available here. (.xsd file, 216MB) or is downloadable here (.zip file, 27MB).
Work Currently being undertaken in NSW
The New South Wales Department of Lands have recently conducted a review of the ICSM ePlan Model and jurisdictional XML Schemas for capturing and representing Australian jurisdictional data with a LandXML document.
The documents, XML Schemas and XML data files, which resulted from the review are intended for use by all ICSM ePlan members and interested third-parties including CAD software vendors.
ICSM is seeking feedback on the review documentation to ensure the endorsed national standard adequately meet the requirements of the surveying profession, software vendors and associated industries. To review the documentaion, provide feedback or register interest refer to the NSW Lands EPlan WEB site.
Working Group Development Phase
At the ICSM meeting in November 2003, it was agreed that a new Working Group should be created to review the options for the development and implementation of a system for the electronic lodgement and transfer of survey information. The primary purpose of this development is to maximise efficiencies inherent in electronic systems and minimising the inefficiencies and costs of using paper for survey records.
The ePlan Working Group was formed in early 2004. At this time the ePlan Terms of Reference that were established:
- Implement communication strategy involving industry stakeholders
- Produce a generic UML model
- Develop or identify standard UML tools for data capture, visualisation and validation
- Develop an XML schema for cadastral survey, infrastructure and survey control objects
- Develop a high level business case for adoption of ePlan standards
- Make recommendations for implementation, review and management of ePlan standards
- Provide advice to ICSM on other areas of electronic survey data transfer
- Provide a work plan and make regular reports to ICSM on progress
It was further agreed that the EARL project team in the Queensland Department of Natural Resources and Water was best placed to undertake the majority of the initial work.
By June 2007 an operational model was installed and in use in northern Queensland offices of the Department of Natural Resources and Water. The system uses LandXML as a data transfer standard to capture, validate and visualise cadastral survey data.
Working Group Implementation Phase
As a result of these achievements, this Working Group has changed its status from a development phase to an implementation phase; although development and enhancement will be ongoing.
The new Terms of Reference are:
- Trialling and adapting the data transfer standard and business objects through implementation in at least two jurisdictions such that:
- Surveyors can complete on line cadastral infrastructure and survey control searches of jurisdictional data bases, receive standard LandXML survey data downloads
- Create a cadastral survey (data) plan using proprietary vendor applications suitable for lodgement with the relevant jurisdictional authorities which can be
- Visualised, validated and approved by the relevant jurisdictional authorities as a spatially and legally valid instrument for land title registration
- Development, publication and maintenance of reference implementation documents, models, standards and business object tools to assist industry implementation
- Provide advice on any other issues/areas where ICSM may be able to provide national leadership in the electronic transfer of land surveying data
