The document discusses the future of geocoded addressing in Australia. It argues that while the current G-NAF property-based addressing system has been successful, it is struggling to meet 21st century requirements for location data like high resolution, timely updates, and support for non-property locations. A more disruptive, crowd-sourced approach is needed that leverages new technologies, uses descriptive location labels, and builds on innovations while still utilizing the foundation of G-NAF. This future system would be facilitated by government but primarily community-maintained with transparent and high-quality open data. A series of collaborative experiments is proposed to help develop this new approach to geocoded addressing.

Editor's Notes
- Add opening graphic
- Fred is a farmer in the Riverina. He wants to insure his farm equipment against flood. To be able to assess his risk accurately and give him the most competitive price, the insurance company needs to know the exact location of the equipment shed on his property. Fred goes online, finds his property record displayed on a recent aerial image, and updates it to include the geocoded location of the shed, as one of the buildings associated with his property. The insurer sees the updated location, determines it is on a higher elevation than the rest of the property and quotes him a discounted premium. Gabrielle lives in an apartment building in St Kilda. She shops online a lot, but finds that couriers or grocery stores won’t deliver because there’s a no-stopping zone at her building’s street frontage. There’s parking and a second entry in the back-lane, but this doesn’t have a street number or official address. Gabrielle goes online to the government location registration page, and updates the ‘delivery’ access details for her unit. Courier companies who subscribe to the same service, now know where to deliver Gabrielle’s new pair of shoes, and she doesn’t have to go and pick them up from the post office.

- Addresses all magically appear are easy and correct.
- The current geocoded address supply chain was not designed, it simply evolved over the past 40 years where local knowledge was often the best resource for identifying location.
- Geocoded addressing as currently provided by G-NAF is too limited in scope by constraining itself to property-based street-addresses, is inherently complex, non-linear and in many aspects convoluted, which creates contradictory evidence in applying confidence levels to address verification and geocoding processes, and reduces data currency. Millions of unverified addresses are captured annually and follow various paths through the supply chain, often involving considerable duplication and manual intervention. While most addresses eventually become verified and many ultimately geocoded, a substantial minority will not be verified (how much this last point is an issue, is yet to be determined).
- By the year 2020, geocoded communication of location in Australia will comprise the infrastructure, processes and knowledge that enable accurate, trusted, timely and unambiguous translation of a descriptive tag to a place in time and 3-dimensional space. The broad community captures, maintains and shares geocoded location data. Confidence in the data comes from its single source of truth, its transparency and auditable provenance. Government’s role is that of a facilitator, ensuring trust, setting relevant standards and (open data) policies, while the market provides value-add, fit for purpose channels.
- Given that many of the concepts and technologies are emerging, implementing a future, longer-term vision will entail at least in part a disruptive approach that needs to re-assess the entire supply chain, and identify which G-NAF elements can be kept/improved (for property-based addressing), and where additional, non-traditional supply-chain elements and approaches are needed as additions. It will encompass a ‘Bazaar instead of the Cathedral’ paradigm shift, with a focus on an open, crowd-sourced and distributed model that complements the current jurisdictional supply chain model. The distinction between users and producers of location data will further blur. Such an approach would also be consistent with the currently emerging and accelerating open data movement. Though originally applied to open source software, it equally applies to other open, community based initiatives such as Open Street Map or Wikipedia.
