What is ePlan?
• National initiative by the Intergovernmental Committee on
Surveying and Mapping (ICSM)
• Managed by ICSM ePlan working group
• National adoption of a data transfer standard
• Specifically for cadastral and survey information
What is ePlan for?
• ePlan will enable the creation of a data file of surveying
information related to a subdivision survey
– It is based on LandXML (an internationally recognised data standard for
the land development industry)
• ePlan file will replace the paper/PDF Plan of Subdivision
– File will be lodged electronically
– Data will be extracted automatically
• ePlan will use infrastructure for the digital lodgement,
exchange, alteration and examination of plans of
subdivisions

Scope of ePlan Investigation
(1 of 2)
• National harmonisation by the adoption of the ICSM ePlan
data model for the requirements of plans of subdivisions in
Victoria
• Consultation with the stakeholders on the adoption of the
ePlan format
– Understanding value of ePlan to, and its use in, DSE and industry
– Engaging the CAD software vendors in the development process
– Capacity building within the subdivision process stakeholders through
running regular workshops and seminars and
– Providing information on ePlan, eg by publishing articles
Scope of ePlan Investigation (cont’d)
(2 of 2)
• Identification of the technical “tools” needed for ePlan and
the options for supplying them. These will/might include:
– a validation tool to be used by surveyors before application
or data lodgement
– an online ePlan visualisation tool
– an ePlan examination tool
– an ePlan database management system
• Investigation of mechanisms for data base updates,
including VicMap property, VOTS, SMES and LANDATA
• Investigation of mechanisms to deliver digital plan data to
users
• Integration with SPEAR
Other Jurisdictions - New Zealand
•
Fully operational
•
Survey-accurate DCDB
•
e-Survey system and LandXML based software for
– Creating, importing and capturing surveys
– Pre-validation of surveys and
– Survey lodgement
•
Digital lodgement of Cadastral Survey Datasets (CSDs) has been
mandatory since 1 September 2007
•
Proposals to provide an offline tool for digital plan generation,
including diagram creation and editing, to improve efficiency for
surveyors.
Other Jurisdictions - Queensland
• Implementing the ePlan model using the Survey
Information Processing (SIP) tool
• All 2D plans are being captured via SIP
• The SIP captured digital data is being used to assist in the
plan audit process
• Moving towards its second phase of its digital lodgement
strategy
– exposing its web services to clients and engaging the industry vendors
to provide solutions to industry.
Other Jurisdictions - New South Wales
•
Building out of the electronic examination tool
•
Developing and documenting data capture methodology for
manually lodged plans
•
Prototyping a lodgement environment
•
Workshops with industry bodies
•
Questionnaires to all surveyors who prepare plans
•
Presentations to regional surveyors groups and industry seminars
•
Designing new plans including separate entities
– Plan drawings
– Administrative data
Other Jurisdictions - Western Australia
• LandXML Project Board being formed
• Still investigating and developing a LandXML format for WA
• Contemplating a LandXML pilot program for plan lodgement
with selected survey companies
• Existing digital format for lodgement
• Existing survey-accurate cadastral database (nearing
completion)
• eLand development (linking digital Approvals and digital
Plans (ePlan))

Matters to be considered - Surveyors
• Introducing new procedures
– Initial discomfort
– Self-checking approach
• Purchasing or upgrading to a LandXML certified software
package
– Necessity for surveyors to upgrade their current CAD software. Need to
develop strategies for surveyors to acquire an ePlan-enabled software
package
• Connection to MGA grid
• Using a survey-accurate cadastral database
Matters to be considered - CAD developers
• LandXML import / export modules
• Certification from LandXML organisation
• Certification from ICSM working group
• Integration with ePlan validation web service
• Integration with ePlan delivery web service
• International CAD software developers
Matters to be considered - DSE
• Survey-accurate cadastral database
– Survey back capture
– Automatic least square adjustment
• VicMap Property / SMES / VOTS / LANDATA updates
• Change to the provision of data to users
• Legislation changes
• Plan examination process changes
• Plan registration process changes
ePlan Benefits - General
• Efficiency in plan preparation
– Fewer geometric and associated human errors
• Efficiency in plan examination
– Labour-intensive nature of paper-based or PDF plan examination
– Reducing risks for the examination process
• Efficient update process for cadastral databases
– Automatic and simultaneous update of the internal data bases –
VicMap property, VOTS, SMES databases, etc
– Survey-accurate cadastral database benefits many other users
• Standardisation
– Compliance with the national digital standard
• Data re-use
– Re-use the data without further enhancement
ePlan Benefits - Surveyors
• Enhance the quality of plan data
– Pre-validation of surveys
• Survey lodgement
• Survey-accurate cadastral database
• Improve access/delivery of survey info
• Reduce anomalies and requisitions
• Improve turn around times
ePlan Project Plan - Progress to Date
•
Testing the standard
– Testing that the standard is complete and comprehensive
– Definition of the Victorian Registrar’s requirements for an
electronic Plan of Subdivision
– Initial proof of concept
•
Setting up for investigating the adoption of ePlan
– ePlan co-ordinator / LV Steering Committee
– Draft Project Plan
– Preliminary consultation plan
•
Using the standard
– Identification of technical issues and needs
– Identification of technical components needed to use ePlan
– Use of ePlan in other areas, eg SII, CAD developers
