� Use sub-metre GPS for rural

asset mapping and

navigation to assets

� Hosting computer infrastructure during pilot studies for new

differential correction services being developed by DSE,

Our Future Directions - GISOur Future Directions - GIS

New GIS bringing new open architecture …..

GIS Spatial Data Base

GPSCADGIS View/Query

� Improved access for consultants and other external users

� Replace proforma based “as constructed” records with

coordinate based system via CAD environment

GIS Data Admin

� Improved view and query environment for users

� Improved integration with CAD and GPS environments

� Integration with new document management system

GIS Power User

Our Future Directions - CADOur Future Directions - CAD

� Improve access to data for design consultants and other

external users

� Engage with industry providers re access to digital subdivision

data for map base maintenance (via SPEAR)

� Review and rationalise in-house CAD system requirements

to further improve interoperability

� Develop, with industry, digital design standards and digital “as

constructed” record systems

� Improve digital data license agreements for external data users

(privacy, liability, meta data)

Our Future Directions - GPSOur Future Directions - GPS

� Support the expansion of MELBpos to provide precise RT GPS

over all urban areas under our jurisdiction

� Extend use of sub metre GPS to operations staff – rural asset

mapping, navigation, environmental mapping

� Upgrade GPS hardware to enable full integration with

VICpos and MELBpos

� Integrate precise GPS into asset recording for new urban

infrastructure constructed by Barwon Water

� Assist external providers working in land development industry

to take up the technology (leadership)

� Investigate a local geoid model for the region

Our Future Directions - GPSOur Future Directions - GPS

� Currently over 1500

ground marks are needed

to sustain current levels of

survey coordination in this

region

� The introduction of

MELBpos and VICpos will

dramatically reduce

dependence on these

marks

� Extending MELBpos

westerly will therefore be

sought

Key Points for the RegionKey Points for the Region

� The map base for this region will soon have enhanced spatial

accuracy, particularly in urban areas, and duplication will be

gone

� Data supply to land development industry is being considered

by councils and by us – can we coordinate & standardise?

� Initiatives for improvements to infrastructure design and

recording are coming, driven by us and by councils – can we

standardise?

� VICpos is here now

� MELBpos is close by and expanding

� Absolute positioning via GPS is now available as a component

of mapping and asset recording systems and will quickly

become the system of choice for the spatial industry
