Using
positional and navigational technology in
Australia ALLAN

The
Australian community, industry and government
benefit from location based technologies
being used to resolve their issues
While digital techniques were introduced to map
production in the 1970’s, the driver for
utilising digital tools to manage this wide range
of activities was the land administration functions
of the six states and two territories. Developed
in concert by the legal and surveying professions,
these state and territory based land administrations
functions led to digital land valuation systems
as early as 1968 in South Australia. Building
upon such initiatives; government guaranteed computerised
land registration and automated valuation systems
have been built.
While these initial land parcel based systems
contained a wealth of locational data (eg land
use, building details, sale prices etc) they relied
on hard copy maps and plans for their graphical
modules. This need to utilise digital graphical
modules to display and analyse land parcel data
led to all states and territories building and
maintaining a digital cadastral databases. These
data bases were completed from 1986 (South Australia)
to 1998 (Tasmania) and form the backbone of the
data used by locational technologies in Australia.
National recognition
of digital cadastral data
Integrated
data combining the individual digital cadastres
and road centre lines are now available from a
joint consortium. The last two national censuses
were successfully conducted using digital data
from this consortium. Seeking to combine commercial
goals and government
responsibilities, the consortium provides these
data to business and governments. In addition
these data are also distributed (under licence)
through software suppliers.
Environmental and
natural resource applications
During
these cadastral developments, natural resource
data was increasingly captured and analysed using
locational technologies. Environmental agencies
have developed sophisticated models to predict
a variety of threats (eg locus, fire, salinity
etc) and are essential to natural resource management.
Paralleling the work of environmental agencies
the mining agencies and industry have developed
3D location based technologies.
Utility applications
Highway
engineers have developed PC based pavement management
systems which use Microsoft products (eg Access
and Excel). By partitioning a road into fixed
length segments and allocating roughness and condition
ratings these tools are used to plan, cost and
maintain roads to agreed standards within constrained
budgets.
Utility infrastructure business (public and private)
have digitally captured the location, function
and interconnections of their assets. These data
are then overlaid on the cadastre and topographic
data to analyse asset decay, failure and demand.
Utilising such analysis, service availability
is improved and costs contained.Route analysis
tools are used by public transport providers and
the waste disposal business (mostly public)to
minimise travel distances and maximise loads for
each journey.
Commercial applications
With few
exceptions, private companies have been reluctant
to publicise how they utilise locational technologies.
Those companies that will admit to using these
technologies argue that to discuss such use and
the outcomes will undermine any commercial advantage
gained by their initiative.
However it is known that locational technologies
have
been used by companies to:
· Focus their marketing on those locations
most likely to purchase their product;
· Identify locations of a higher insurance
risk (eg criminal activity, fire etc.);
· Identify non-commercial bank branches
(i.e. a mismatch between bank products and the
population’s characteristics);
· Evaluate site suitability (particularly
the fast food chains); and
· Manage their vineyards.
Some of these tasks are undertaken by third party
companies, such as a company which undertakes
street address based data cleansing. This process
uses a clean and complete street address data
base to correct the commonly used location key
of street address in a company’s files.
Then duplicate records are removed from their
client company’s customer data base and
the client company is able to more effectively
market their products to their existing customers.
Integration of mobile
and management applications
While emergency
services are using locational technologies to
reduce response times and the size of their fleet,
these technologies are also being used for counter
terrorism purposes. The locational technologies
used by these services are usually integrated
with other information technology to provide a
more complete management system, which will typically
include a locational analysis module. Some of
these services also have a GPS enabled fleet to
provide real time fleet monitoring
Social applications
The location
of health service delivery (both the actual location
and the services delivered at each location) is
analysed using locational technologies. This analysis
is then used to relocate services in a more socially
equitable and efficient way. Similar analysis
is also performed by education and social services
agencies has resulted in the development of a
“remoteness” index which is now used
by the Australian government across a number of
portfolios for the delivery of services.
Defence
applications
The Australian
defence forces were the first body to develop
automated
digital mapping techniques for map production
in the early 1970s. The military continues to
have a high commitment to the use of locational
technologies across a range of logistics, training
and combat applications.
Policy barriers
At the
same time there are still a significant number
of public and private sector entities that are
yet to use, or underutilise, location based technologies.
Hence there remain many opportunities toexpand
the use of these technologies in Australia. Many
see these opportunities restricted by locational
information being sold by public agencies (including
to other public sector agencies) on the “user
pays” principle. These critics see locational
information as a fundamental infrastructure of
a modern economy.
Until the advent of digital locational information
(i.e. topographic, cadastral, census and environmental
data); locational data in hard copy
map formats were seen as part of the fundamental
infrastructure of a modern economy. However the
speed of dissemination and the additional cost
of creating and maintaining digital data fuelled
the view that the user should pay this additional
overhead to government. This debate continues
in each of the jurisdictions that collect and
distribute digital locational data (i.e. each
of the six Australian states, two territories
and within the Australian government).
Whatever the accuracy of the criticism the only
barriers to open access to locational data in
Australia are price and the Privacy Act. The Privacy
Act stops public access to any records that contain
sensitive personal information (name, address,
health, finance), but allows public access to
consolidated data (from which you can not identify
individuals).
However, while not being a barrier to data access,
the various formats and data standards add to
the cost of integrating locational data. There
are more and more tools being developed to address
this data integration issue; however unless each
data set’s Metadata is carefully considered
it is unlikely that data from a variety of sources
can be successfully integrated.
In addition unless the data access is governed
by robust and well administered policies, a potential
user may not be able to access the data they require
for their task. The on-going attempts to have
common data access and use policies for Australia
are yet to be realised (in practice) by all of
the jurisdictions.
Typical professional
attitudes
The acceptance
of locational technologies into every day applications
has (and is) driven by the passion of the locational
enthusiasts. These enthusiasts have included:
map makers, land valuers, land registration officers,
environmentalists, town planners, civil engineers,
geographers and surveyors.
The most resistant professions to the introduction
of locational technologies have been those with
little or no background in graphical analysis
(eg accountants and professional managers). To
overcome this resistance Price Waterhouse and
Coopers were commissioned to undertake a national
cost benefit analysis of land information and
its uses. As this study by a major management
consulting company identified significant benefits,
it is often quoted when seeking “treasury”
approval for new locational projects.
Many of the organisations that introduce locational
technologies focus on more efficient processes
and delay the decision support applications. A
typical more efficient process is reducing the
staff time and effort to contact those living
within a specific location. This function is required
by planning regulators to contact abutting land
owners during a planning approval process; or
for civil engineers to contact those about to
impacted by a civil engineering works.
However, once the technology is delivering real
identifiable benefits, the technology’s
critics become willing supporters of expanding
its use to decision support. This change in attitude
is seldom quick, but once converted to the value
of locational technologies the initial critics
can become its major sponsor in an organisation.
Such a change of attitude has led one state to
merge its locational technology policy development
into its general information technology policies
and strategies.
Relevance to Indian
Debate
These summary
reflections of the development and challenges
of fully utilising locational technologies are
not offered as a blue print. Rather these reflections
are offered to assist the Indian debate of the
most effective way to gain widespread acceptance
positional and navigational
technologies in your jurisdictions.
