The first point of call for discovering
Tasmanian Spatial Data is LISTdata.
LISTdata is a free, easy-to-use online
data portal for cataloguing and discovering
spatial data in Tasmania. It is accessible
from the home page of the LIST, or directly
LISTdata stores ANZLIC standard
metadata in an easy human readable form
(and a machine readable format, too), which
provides the fundamental information users
need to make an informed decision about
selecting and/or using a particular dataset.
In addition to this, LISTdata is the central
location that provides all options to discover,
view, connect to or download location data,
by linking to other LIST infrastructure
components including LISTmap, LIST open
data and LISTservices.
LISTmap is accessible from the home
page of the LIST or directly at http://maps.
thelist.tas.gov.au. It provides a free, easy-to-
use online map viewer that allows users to
combine multiple layers of information to
create powerful images that communicate
ideas, help with decision-making and
encourage a better understanding of
changes in the environment. LISTmap has
a vast array of features including (to name
a few): a simple search bar for finding
a location, a selection of background
basemaps, including Google imagery and
Street View, the ability to synchronise with
your device's GPS, integrated links to land
titles and property documents, customised
mark-up and bookmarking, and printing
and hundreds of layers of authoritative
The latter feature is now even more
powerful, due to LISTmap's Export
feature that allows a user to 'clip and ship'
an extract of data directly to their PC or
device. By setting the screen to the desired
area and completing the two-step process
shown on the screen, a user can have a
current extract of data in shape, mapinfo
or geodatabase format within minutes.
Users who are interested in a pre-set
local government area can now access free
data via LIST open data. This simple to use
website is accessible from the LISTdata
home page (http://data.thelist.tas.gov.au),
or directly at http://listdata.thelist.tas.gov.
au/opendata/. Data is refreshed every six
months and is delivered in shape, mapinfo
and geodatabase format in most cases, all
under the Creative Commons BY Licence.
This interface has proved very popular, with
over 700 compressed data files downloaded
on average each month since its launch
in May this year. This amount is already
over three times the yearly average of
custom data extracts previously performed
manually by Land Tasmania staff.
One of Land Tasmania's fastest
growing areas of interest is business-
to-business services -- or web services.
The LIST infrastructure was designed
with a services-oriented architecture
in mind, particularly so when it comes
to the delivery of location-based data.
Users are able to access LISTservices
via a public web service end point at
services can be consumed via many
common GIS applications, mobile
programming interfaces (API). Users are
able to seamlessly integrate authoritative
government data into their business
systems via these REST-based services.
Each service or layer is attributed with the
respective Creative Commons Licence, so
users can quickly ascertain what they can
use the service for. A range of businesses
have utilised LISTservices, including the
Tasmanian Government's emergency
services website TASALERT (www.alert.
tas.tas.gov.au ), for example.
"Our open data initiatives have been
a major step for Land
Tasmania. It provides the
Tasmanian community with
improved access, and choice
in sourcing authoritative
government location based
data," said Land Tasmania
client services manager Todd
Baker. "Given its success and
uptake, Land Tasmania is
now looking to release more
datasets under 'Open Data'.
