and project control, surveillance
monitoring and urban asset
mapping
� 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,
VICpos and MELBpos
� Assisting with field testing of both systems and developing
new asset recording processes to use them (reforming

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
