Australian Drainage Divisions (ADDs) are an ABS approximation of drainage divisions. Drainage divisions are defined by major landscape features and climatic zones to form broad hydrological regions as represented in the Australian Hydrological Geospatial Fabric (Geofabric, 2014 version 2) developed by the Bureau of Meteorology. Unlike in 2011, when the Australian Drainage Divisions were built from Statistical Area Level 1 (SA1), in this edition they have been built from Mesh Blocks. Further information about these regions can be found in the following publication: Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structure, July 2016 (cat no. 1270.0.55.003). http://www.abs.gov.au/ausstats/abs@.nsf/mf/1270.0.55.003 |
