  10. Improved Spatial Accuracy RE Plans Complete • Custodian Empowerment Reduce Duplication of Effort Quicker Turn Around Direct Editing Future Directions

  11. Direction 1: Spatial Accuracy Improvement Current Accuracies • 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

  12. 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

  13. Hand held GPS devices • Higher resolution aerialphotography • Changing Work Practices Developments Highlighting Spatial Issues

  14. 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

  15. 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

  16.
