Address coding, a form of geocoding, is a process where a unit
record is assigned to a latitude/longitude point on the ground,
or "coded" to a small area, such as a Mesh Block, by using the
address. Once this has been established, the unit record can
then be assigned to a larger geographic area. The data can then
be added to other unit records that are assigned to the same
area, thus providing aggregate values for the new geographic
area. If latitudes and longitudes are available, then it is
possible to code these units to any level of the ASGS. This is
the most accurate method for the transition of existing data.
This removes the need to apply a mathematical transformation, as
data coded to a point can be aggregated accurately to any area,
regardless of its geographic base. The overall effect is an
accurate recoding of the original data. If a complete street
address is available - that is street number and name, Suburb or
Locality, State or Territory (S/T) and postcode - it is also
possible to code the units
