Physiographic Regions of Australia
The Physiographic Regions of Australia (Pain, Gregory, Wilson and McKenzie 2011) are a modification of those compiled by Jennings and Mabbutt (1977), and are based on a visual interpretation of landforms as expressed on the Shuttle Radar Terrain Mission (SRTM) digital elevation model (DEM). Apart from its descriptive role, a map of physiographic re... moregions provides a regional system of reference for geomorphological and related physical geographical accounts. Through the groupings of physiographic regional characteristics at different levels, the action of underlying controls, for instance geologic or climatic, may be made apparent. Further, the map can provide a regional basis for an understanding of land characteristics that are dependent upon landforms, for example the distribution of soils or natural vegetation.

The Physiographic Regions were digitized or scanned from line work on 1:1 000 000 maps of elevation (SRTM 90m), shaded with an illumination in the NW. Lines were drawn onto the maps (with 4B pencils), by comparing the original lines of Jennings and Mabbutt and the landform patterns that could be seen in the SRTM hill shaded data. State and territory agencies provided corrections and updates to this initial line work, which were also digitized. Line work in Western Australia has been altered significantly, so that it approximates to an aggregation of the state soil landscape survey boundaries.
The 1:100 000 Geoscience Australia Coastline (2004) has been used, rather than state specific line work, to provide national consistency. Attributes within the accompanying database were attached to the polygons via the region_id.
The nominal scale of this dataset is 1:2 500 000
Attribute accuracy is consistent across the dataset. Polygon ID's were used to join attribute data that was entered and managed in an Access database. ID's, names and descriptions have been checked for accuracy and consistency. Regolith materials are a concatenation of 3 materials listed in the database, including proportions.
The spatial dataset has been checked for overlaps and gaps, and correct labelling.
The dataset coverage is complete for the whole of continental Australia.

The Australian Collaborative Land Evaluation Program (ACLEP) was established in 1992 and is a proven model for national cooperation, collaboration and effective multi-jurisdictional activity. ACLEP is a partnership between CSIRO Land and Water, the Australian Government Department of Agriculture and the state and territory agencies responsible for ... moreland resource assessment. It provides a focus for the collection, collation, management, dissemination and analysis of nationally consistent, integrated data and information on soil and land resources. It provides input to national assessments of the consequences of land resource use and management.
ACLEP delivers on a vision that “natural resource management in Australia is underpinned by appropriate soil and land resource information and knowledge to ensure sustainable economic and environmental systems”.
ACLEP is currently funded by the Australian Government Department of Agriculture and CSIRO. States and territories provide significant resources in support of ACLEP projects and activities. ACLEP is managed through the CSIRO National Soil Information Centre and is directed and coordinated through the National Committee for Soil and Terrain (NCST). The NCST has representatives from all State, Territory and Australian Government agencies with mandated responsibility for soil and land information. DAFF provides secretariat support to the NCST. less
The Australian Soil Resource Information System (ASRIS) provides online access to the best available soil and land resource information in a consistent format across the country. ASRIS has been developed for a broad range of users including natural resource managers, educational institutions, planners, researchers, and community groups. The initial... more phase of ASRIS has had an emphasis on data acquisition to ensure the continuity of a national dataset. A set of interpretations are currently being developed to demonstrate ASRIS's capabilities.
ASRIS uses a hierarchy of mapping units with seven levels. The upper three levels provide descriptions of soils and landscapes across the complete continent. Lower levels provide more detailed information where field surveys have been completed. A consistent set of land qualities is described for map units (tracts). Descriptions from the lowest level feed into summaries at higher levels. Information relates to soil thickness, water storage, permeability, salinity, fertility, and erodibility. ASRIS includes a soil profile database with fully characterized and representative sites.
Estimates of uncertainty are a feature of the system. A distinction is made between attribute uncertainty (due to measurement for a given soil material) and spatial uncertainty (due to natural variation across a landscape). These estimates are provided to encourage formal analysis of the uncertainty of predictions generated using ASRIS data (e.g. crop yield, runoff, land suitability). ASRIS is being released in stages. At the end of 2007 the upper levels will be completed across the country. There will be a restricted coverage at lower levels. Data will also be available for approximately 10,000 representative profiles. less
