ASGS Statistical Area Level 1

Statistical Area Level 1 (SA1s) are designed to maximise the spatial detail available for Census data. Most SA1s have a population of between 200 to 800 persons with an average population of approximately 400 persons. This is to optimise the balance between spatial detail and the ability to cross classify Census variables without the resulting counts becoming too small for use. SA1s aim to separate out areas with different geographic characteristics within Suburb and Locality boundaries. In rural areas they often combine related Locality boundaries. 　

ABS ASGS State Boundaries

State and Territory (S/T) are separate spatial units representing the States and Territories within Australia. Jervis Bay Territory, the Territories of Christmas Island; Cocos (Keeling) Islands and Norfolk Island are included as one spatial unit at the State and Territory level under the category of Other Territories. 　

S/T are aggregations of one or more Statistical Area Level 4 (SA4s) in the ASGS Main Structure. 　

S/T boundaries are contiguous and, in aggregate, cover the whole of Australia without gaps or overlaps.

1 second SRTM Derived Hydrological Digital Elevation Model (DEM-H) version 1.0

The 1 second SRTM derived DEM-H Version 1.0 is a 1 arc second (~30 m) gridded digital elevation model (DEM) that has been hydrologically conditioned and drainage enforced. The DEM-H captures flow paths based on SRTM elevations and mapped stream lines, and supports delineation of catchments and related hydrological attributes.
