Geospatial data provider PSMA will implement changes to the G-NAF dataset in the upcoming August release.
The change focuses on a process that some users have found challenging when tracking addresses.
For example, when a property changes from a lot number to a rural address with street numbers, the tracking may be lost. The new Address Feature table will contain both principal and alias addresses, with the added ability to retain retired addresses.
