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
