Outline • Introduction • Current Status • Current Issues • Future

Introduction

Victoria Area < 3% of Australia Population 24.9 % of Australia)

2004 CGSIC Report • 21 Sep 2004 Long Beach • Issues • Policy Framework • Location Based Services Project • Implications for Victoria • Realisation of the datum • Reg 13

Current Status

Policy Framework • Continues to be important • Provides the policy context for positioning infrastructure • Within Policy, positioning is becoming more important • Facilitates other activities • Exposes quality issue in other spatial DB • Coordination of infrastructure

LBS • Planned to have about 0.5 m accuracy real time solution over Vic • Delivered Dec 2004

Implications For Vic • For all practical purposes GPSnet is the realisation of the geodetic datum in Vic • Now have Reg 13 Certificates on 18 Base Stations

Victorian GPS Base Station Network

Comparison

Current Issues

Current Issues • Networks solutions not quite there • Inter Station Distance too small • Poor understanding of how they work • Low sat numbers a problem at times • Driving changes in spatial data • Increased spatial accuracy in mapping • Coordination • Multiple software systems on the one network • Hardware Costs down, but operators still have high costs • CRC SI • NCRIS

The Future

The Future • State wide • Real time • 2-3 cm Horiz Accuracy • 3-5 cm Vertical Accuracy
