Alone, data isn’t much use to anybody. Isolated and unverified, it has little purpose beyond what is essentially an information opinion. In Australia, at least with regard to addresses, there are two high-quality reference sources available.
The first is the Postal Address File (PAF) – a list of all Australia addresses that Australia Post delivers physical mail to, compiled and managed internally by Australia Post.
The other is the Geocoded National Address File (G-NAF), based on registered sections of land by state and local governments. The G-NAF is collated from a range of data, not limited to federal mapping authorities and government agencies.
How can a business make use of individual data, especially that which is user-entered and often at the mercy of human error?
So how can a business make use of individual data, especially that which is user-entered and often at the mercy of human error?
We’ve discussed previously the benefits and purpose of either address file. For a business or organisation that needs a wider and more complete set of address information – to identify hazard areas of a city or populated area, for example – the greatest level of accuracy is afforded by searching across both data sources.
The Harmony Link Table
Making both the PAF and G-NAF data sets simultaneously available in Harmony ensures that users have the most comprehensive and complete access and cover possible of Australian addresses.
However, Mastersoft has found that – for many applications – the amalgamation of the two files into a single reference set can lead to confusion and misrepresentation of results.
So instead of combining the two, Mastersoft has a created a Link Table that cross references all entries in each set and completes the data in each of them by appending unique fields from one to the other. This means for example:
- Users can decide which data source to search under which conditions.
- G-NAF addresses include postcodes.
- PAF addresses include Geocodes and related codes to the same level of accuracy as an equivalent G-NAF address or to street or locality level where applicable.
The Link Table architecture enables inclusion of additional data sources, such as address or location data.
Information that paints a clear picture
Statistics released towards the end of 2012 look to compare both data sources, a result that clearly illustrates the value of the Mastersoft Link Table.
Upon comparing both the PAF and G-NAF for total number of useable addresses, there are a total of 13 million address – 2 million of which are obtainable only through use of the G-NAF data source.
According to the compared statistics, the Link Table features the following:
- 99.35 per cent of all PAF street addresses are geocoded and linked at point level.
- 95.56 per cent of all PAF postal addresses are geocoded and linked at locality level – this can be increased to 100 per cent with an additional and supplementary data source.
- There are 15.42 per cent – 1,948,976 as of November, 2012 – G-NAF street addresses not in the PAF.
From this, 99.7 per cent of all addresses in Mastersoft Harmony Hosted G-NAF include a postcode. This is almost a polar opposite when compared to the original G-NAF file released and provided by the PSMA, which contains a fraction of this number – only 1.3 per cent of addresses in the G-NAF include postcodes.
