State of Victoria
Background

Geospatial developments in Victoria
 topographic mapping (1970's - all digital 1994)
 digital cadastral mapping (1980 - 1994)

1980's focus on land administration
 legal / fiscal reform
 narrow focus

1993 requirements study
 to develop a strategic framework for GIS
development in Victoria
 major investigation (over 18 months)
 covered approx 40 state agencies and reviewed
270 datasets

Content & Quality Requirement

For the State Digital Cadastral Mapbase
 an authoritative state-wide coverage of land units
 clear, current and correct parcel and property
land units
 key land unit linkages to various agency
databases established
 single dataset maintenance regime
 support for exchange of land information
between agencies
 the ability to perform topologic (spatial) analysis

Common Spatial Infrastructure
between State & Local Government

Establish a secure supply of property information
from Local Government
 create a property 'layer' in the Cadastral Mapbase
from Local Government's records
 establish correct relationships between properties
and parcels
 ensure timely maintenance of all property details
(including street address, road name, suburb /
locality names)
How? … introducing the
PROPERTY INFORMATION PROJECT
GSDI 6 Conference - From Global to Local : 16-19 September 2002, Budapest, Hungary
Property Information Project
‘Proposition’
State Government provides:
Products
 Mapbase (framework)
Funding
 data reconciliation (matching
property & parcel data)
 new addressing - locality
definitions, road naming,
property numbering
 migration of property data into
Cadastral Mapbase
Services
 on-going maintenance
Local Government agrees to:



adoption of Mapbase
supply Land Victoria with all
(proposed) plans submitted
by developers
timely supply of all relevant
property changes (street
addressing, road names,
localities, etc)

The analysis stage led to preparation
of a draft work plan covering:
 matching of property and parcel
records
 automatic pass
 manual reconciliation
 basic addressing, allocation of
numbers, naming of roads
 establishing maintenance loop
(HW/SW)
Plan was refined and funding agreed
Contract entered into between State
and Local Government Contract also
covered on-going maintenance
Specified data formats, frequencies,
quality, service levels, etc, both ways

Summary & Conclusion






Governments are key generators of spatial
information
Effective SDI’s may require partnerships
between National, State &/or Local governments
Institutional barriers in establishing data
infrastructure remain the most difficult to resolve
PIP has demonstrated a cooperative model
between Local and State Government in Victoria
PSMA provides the State and National linkage
Two very different models - common objective...
GSDI 6 Conference - From Global to Local : 16-19 September 2002, Budapest, Hungary
Summary & Conclusion



Both are cooperative models (no legislation)
Both feature people and relationship building
(partnerships)
Takes time…
 PIP commenced in mid 1997 (75/78)
 PSMA started incorporation 4 years ago

SDI is common infrastructure & everyone’s
responsibility:
From my Dataset… to our Infrastructure
