Future Directions
RE Plans
Complete
• Improved Spatial Accuracy
• Custodian Empowerment
Direct Editing
Quicker Turn
Around
Reduce Duplication
of Effort
Direction 1: Spatial Accuracy Improvement
• 3.75% points .1 metre• 47.65% points .5 metre • 20.21% points 2.5 metres• 5.20% points 10 metres• 22.71% points 25 metres
Current Accuracies
Incremental Spatial Upgrading• Utilising Digital Subdivisions to Improve
Accuracy• Extracting Coordinates for Fieldnotes• Re-established 4 growth corridor areas• Adjust a Region using Survey control &
Photography• Adopted higher accuracy data from other
authorities
Developments Highlighting Spatial Issues
• Higher resolution aerial photography
• Hand held GPS devices
• Changing Work Practices
Spatial Upgrade Business Case• Identifies the impacts of spatial
changes
• Details the benefits of improving the spatial accuracy
• Assesses change options available
• Outlining funding options
Business Case Preferred Option
• 10 year process to spatially upgrade state– All Urban & Peri-Urban Areas 0.05 m
• Existing observations and field control infill
– Rural Areas – 0.1 m to 10 m• Mathematical Adjustment to high resolution Aerial
Photography• Control either derived from aerial photography
and/or field control
Direction 2: Custodian Process Control / Real Time Access
• Current practices are restricting– Source Data Custodians cannot make any changes to the
data– Turn around time frames can be up to 5 weeks from
creation of work order
• Introduction of Notification and Editing Service – Improved process transparency – Given custodians power of veto – Didn’t improve turn-around or provide edit ability

Desired Maintenance Environment
• Centrally Stored Master Copy• Web based tool to facilitate maintenance
material incorporation into the master copy– Incorporate data from Custodian Editor packages– Provide GIS package for simple edits
• Business custodians able to edit their data in VSDL directly;– Retaining an editing service
• Hourly turn around of maintenance edits within production copy
