Home' Position : Position Feb Mar 2015 Contents This huge land asset is managed
through the cadastral system, in
conjunction with the registration system.
It is the lever that defines and reinforces
property rights in the context of location.
With an estimated number of house-
holds approaching 9 million across
Australia and an anticipated 11.6 million
by 2031 , it is crucial that the intergenera-
tional transfer of land is guaranteed.
Looking to the future
Cadastre 2034 considers the user commu-
nity in its vision for the future. The better
the information landowners, investors
and land managers have the better use
they can make of their land asset.
“Knowing the broader interests on
land is important,” said ICSM chairman
and surveyor general SA Michael Burdett.
“People want a clear understanding about
what they can do with their land, what
they can’t do, and what they must do.”
ICSM envisages a cadastral system that
enables people to readily and confidently
identify the location and extent of all
rights, restrictions and responsibilities
related to land and real property.
Currently, rights, restrictions and
responsibilities (RRR) are not digitally
depicted in many jurisdictions.
Linking the digital cadastre to other
legal and social interests on land is a major
goal of Cadastre 2034. It recognises that ef-
fective decision making and informed use
of land will only come about through the
integration of a wider range of information
within the broader cadastral framework.
“Future systems need to evolve beyond
simply recording the extent of land and
ownership,” said PCC chairman and chief
inspecting surveyor WA Richard Browne.
“There will be a significant increase in
the amount of legal and environmental
information over the next 20 years, and
the community will expect to be able to
access this information easily.”
Today’s location information can be
accessed faster than ever before. This
trend will continue and it is likely to put
pressure on governments and industry
to provide more powerful viewing
capabilities to capture the 3-dimensional
nature and dynamic characteristics of
land and real property.
Industry responded positively to the
potential for 3-dimensional applica-
tions and suggested the management of
solar energy access rights, assistance for
emergency services to protect above and
below ground infrastructure, and manag-
ing height restrictions around airports as
fulfilling an important social need.
Nonetheless, a 3-dimensional
representation of land and real property
is an ambitious objective and industry
was quick to recognise the inherent
complexities. Current methods make the
task potentially cost prohibitive.
Even so, there is general agreement
that our infrastructure is proving more
difficult to visualise in two dimensions
and that the future cadastral system will
need to be able to cope with the increas-
ing densification and complexity of devel-
opments both above and below ground.
While Building Information Model-
ling (BIM) has potential to increase the
visualisation of land and real property, the
challenge will be to apply BIM to the ap-
propriate legal and functional standards
required of a future cadastral system.
Future-proofing the cadastre
Cadastre 2034 takes an all-encompassing
view of how the cadastral system of the
future is designed, organised and operated
efficiently. “Strategically, we need to
consider not only the impact on our
environment, but also how we develop,
use and preserve cadastral information
resources,” Richard Browne said.
Continued process improvement and
the progressive adoption of time-saving
technologies will continue to shape our
journey towards 2034. The surveying
and spatial industry is sure to embrace
these changes as it has in the past. The
key will be to ensure that our cadastral
systems remain secure, accessible,
transparent and efficient overtime.
Public confidence in our cadastral
system is paramount.
Industry unanimously supported the en-
during principles espoused in the strategy.
Unease with community
One of the most significant challenges
for industry will be to embrace the
community as part of the cadastral
framework. ICSM proposes a
participatory model to include community
volunteered data for the sustainable
collection of land and property features.
This was a source of concern for in-
dustry and required clarification. There is
agreement that the community will have a
role to play in the 20-year vision, particular-
ly in the short term through the collection
of interests on land. However, mechanisms
will be required to differentiate authorita-
tive and anecdotal sources to maintain the
integrity of a broader cadastral framework.
The use of mobile devices by the
community for locating and visualising
land boundaries rang alarm bells for
some. Industry calls for the strategy
to include warnings, qualifiers and
disclaimers around the use of these
devices for ‘locating’ boundaries.
Concerns are twofold: the lack
of technical competency of users to
make informed decisions on how the
information is best used, and the risk of
litigation due to the inaccuracies inherent
in current digital cadastres.
These concerns reinforce the strategy’s
goal of working towards a more accurate
digital cadastre in the future.
A federated cadastre
There was universal support for unified
access to jurisdictional cadastres.
Currently, consumers source data from
multiple agencies, and collate and manage
this data independent of other users.
ICSM is working closely with ANZLIC
to establish the Land Parcel and Property
Data Theme as part of the National
Spatial Data Framework.
“This data theme is the first step
towards understanding and managing
trans-boundary issues, and addressing
economic, environmental, social and
cultural issues in the national interest,“
Michael Burdett said. “ICSM will continue
to engage with government, industry
and academia in the evolution and
implementation of Cadastre 2034.”
