This is Version 1 of the Soil Depth product of the Soil and Landscape Grid of Australia.
The Soil and Landscape Grid of Australia has produced a range of digital soil attribute products. This depth ... moreproduct estimates the depth of soil down to 2 metres. The digital soil attribute maps are in raster format at a resolution of 3 arc sec (~90 x 90 m pixels).
The soil attribute products are provided as continuous maps that represent each of six depth intervals to a maximum depth of 2 metres. We acknowledge that soil depth is variable across Australia, and in some landscapes there might be no soil or soil might be shallower than 2 metres. We have provided continuous maps because of the relative unavailability of data on soil depth. Further, existing data on depth is biased to near surface layers and there are few records that extend beyond 1.5m. Therefore, we provide here, our best estimate of soil depth to allow users to generate masks, which might be used together with the attribute maps to approximate the presence of areas with no soil or areas with shallow soil. We encourage users to draw on local data and expertise for such assessments.

1181.2 TERN Facility No9 InfoGrid GRUNDY - National Soil Grid - Published 16 Mar 2018
Soil depth is one of 19 attributes of soils chosen to underpin the land suitability assessment of the Flinders and Gilbert Agricultural Resource Assessment (FGARA) project through the digital soil map... moreping process (DSM). This raster data (in GeoTIFF format) represents a modelled surface of soil depth measured in 0.00m and is derived from measured site data and environmental covariates. It generally does not represent soils deeper than 1.5m as the input data was only recorded to a maximum of 1.5m where possible. The data is used in assessment of the requirements for physical support for the plant.
The attribute data file is named "SoilDPredictions.tif".
Also included are data reflecting confidence of the main dataset. This file is named "soilDepth_SD.tif". "SD" represents "standard deviation".
The DSM process is described in the technical report: Bartley R, Thomas MF, Clifford D, Phillip S, Brough D, Harms D, Willis R, Gregory L, Glover M, Moodie K, Sugars M, Eyre L, Smith DJ, Hicks W and Petheram C (2013) Land suitability: technical methods. A technical report to the Australian Government for the Flinders and Gilbert Agricultural Resource Assessment (FGARA) project, CSIRO.
This raster data provides improved soil information to identify opportunities and promote detailed investigation for a range of sustainable development options and was created within the “Land Suitability” component of FGARA projects.less
