PSMA Location Data Update

March 2016

Overview of the February data release and forthcoming events.

In this issue:


The brave new world of open data

After the initial announcement at [email protected] 2012 that the Australian Government was looking to make G-NAF available to the broader economy; two of PSMA's datasets, G-NAF and Administrative Boundaries were released by the Australian Government under open data terms on 26 February 2016.

In a statement announcing the release, the Assistant Minister for Cities and Digital Transformation, the Hon Angus Taylor, said that the Australian Government "...has taken an important step in promoting innovation by releasing one of the most requested and high-value digital datasets to the economy, PSMA Australia Limited’s Geocoded National Address File (G-NAF) and associated Administrative Boundaries dataset."

For PSMA, the Australian Government's release of our flagship product under open data terms is no doubt a game changer. We understand that this is a major disruption to the market that will impact all our partners. But we also see the opportunities, not just for the broader market that now has access to these datasets, but also for our geospatial industry.

For our value-added reseller and integrator partners, the experience and expertise you have developed over the years to handle these complex datasets and use them to create business-ready solutions will now be needed by a much wider market. We are keen to promote each of our partner's unqiue value proposition, and I understand that my Relationships and Engagement staff are already in contact with many of you to progress this.

For our direct clients, many of the sharing restrictions are now lifted, and we look forward to working with you to facilitate greater use of location intelligence in your organisations.

The first quarter of 2016 has been huge for us, and the pace is set to continue with an events-packed second quarter. In March I spoke about the importance of trusted location data in achieving that sweet spot between privacy and security at the AIIA Summit in Canberra. In the next couple of months, PSMA will also be at the Locate Conference, Connect Expo, CeBIT and the EuroGeographics Extraordinary General Assembly. I look forward to seeing many of you along the way. In the meantime, stay in touch with us:

February data release

Changes in confidence levels between releases

In G-NAF, the confidence level of an address reflects the number of contributors who support, or supply, that address. As you can imagine, this support can change from time to time; whether it is a contributor providing an address they have not previously supplied, or a contributor no longer supporting an address, perhaps due to the redevelopment of a site or the replacement by a rural address.

As we are aware that some users rely on the confidence level to indicate whether something exists at an address point, we wanted to flag with you that confidence levels can change from time to time, and we've prepared a number of examples of where this has occurred.

Please use this legend in viewing the examples.

The following images of G-NAF address points covering a small area in South Australia endeavour to reflect the manner in which confidence levels can change from time to time.

In this example, the increase in confidence levels is the result of some addresses that had a retired status in November 2015 being supplied a contributor in February 2016 and as such have a positive contributor value. 

In this example, the decrease in confidence level reflect addresses that have been retired.

Retirement of lot numbered addresses in WA

In the February 2016 release, the West Australian jurisdiction removed some 13,000 lot numbered addresses from its address supply. These addresses were on sites where no dwellings or commercial development has taken place. We've provided an example where the lot numbered addresses retired were part of subdivisions where no dwellings currently exist. While the road casements exist in the cadastre, there are no formed roads.

Retirement of addresses

This example is on Sunnyholt Road in New South Wales where the jurisdiction updated the relationship between the property and the parcel resulting in changes to the addresses. Previously there had been a one to one relationship between the parcel and properties effectively resulting in an address for each parcel.  The update has resulted in multiple parcels now forming a single property with corresponding addresses. As the addresses relate to the properties, some 83 addresses have been moved to a retired status as shown in the February 2016 image.

Parcel level addresses

The Queensland jurisdiction allocated 305 parcel level addresses to the locality of Badu Island in the February 2016 release. Previously there were 190 addresses at street locality level and 59 at locality only addresses supplied by Commonwealth agencies. With the addition of the jurisdictional addresses many of the existing addresses matched thus reducing the street locality addresses to 58.  The locality level addresses remain at 59.

New product update

The first phase of Geoscape, a world first in capturing the built environment on a whole continent, is going well and we expect to have some exciting news to share with you by the next issue of this newsletter. As you would expect with a new product, there have been a number of challenges in reconciling available data and technologies with market requirements. However, our team is working hard to address the challenges as they occur and early market feedback has been overwhelmingly positive.

Don't forget to subscribe to keep up to date with Geoscape's development.


PSMA out and about

AIIA Summit

PSMA is been working with the AIIA to build awareness of the benefits of location data within the ICT industry. Following the successful launch of our whitepaper Realising the value: Understanding open and value-added spatial data to the AIIA membership, PSMA's CEO, Dan Paull joined a panel discussion on privacy and security in a data-driven world at the annual AIIA Summit. Watch the video below for Dan's explanation on why location data should be part of the conversation on privacy and security.


Once again PSMA is supporting the geospatial industry's annual conference, Locate16, 12 to 14 April at the Melbourne Convention and Exhibition Centre. Check out Dan's keynote presentation, Navigating the Future, which will follow directly from the opening plenary speaker, the Hon Angus Taylor, Assistant Minister for Cities and Digital Transformation. Come visit PSMA's staff at our exhibition booth for a personal tour through Geoscape

Connect Expo

This year PSMA will be hosting a roundtable discussion at the Connect Expo, the premium ICT event in Victoria. Sign up to join our Rountable #27 to hear about the Geoscape project and how you can be a part of this world first development. We will also be hosting a exhibition stand in the main hall so if you're visiting the Expo, please come and say hi.
