Soil and Landscape Grid National Soil Attribute Maps - Bulk Density - Whole Earth (3" resolution) - Release 1
This is Version 1 of the Australian Soil Bulk Density - Whole Earth 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. Each product contains six digital soil attribute maps, and their upper and lower confidence limits, representing the soil attribu... morete at six depths: 0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm and 100-200cm. These depths are consistent with the specifications of the GlobalSoilMap.net project (http://www.globalsoilmap.net/). The digital soil attribute maps are in raster format at a resolution of 3 arc sec (~90 x 90 m pixels).
These maps are generated by combining the best available Digital Soil Mapping (DSM) products available across Australia.

Digital Soil Mapping
The National Soil Attribute Maps are generated by combining the best available digital soil mapping to calculate a variance weighted mean for each pixel. Two DSM methods have been utilised across and in various parts of Australia, these being;
1) Decision trees with piecewise linear models with kriging of residuals developed from soil site data across Australia. (Viscarra Rossel et al., 2015a);
2) Disaggregation of existing polygon soil mapping using DSMART (Odgers et al. 2015a).
Version 1 of the Australian Soil Property Maps combines mapping from the:
1) Australia-wide three-dimensional Digital Soil Property Maps;
2) Western Australia Polygon Disaggregation Maps;
3) South Australian Agricultural Areas Polygon Disaggregation Maps;
4) Tasmanian State-wide DSM Maps.
These individual mapping products are also available in the Data Access Portal. Please refer to these individual products for more detail on the DSM methods used.
We thank the CSIRO, Terrestrial Ecosystem Research Network (TERN), the Australian Government through the National Collaborative Research Infrastructure Strategy and the Super Science Initiative, for funding the project. We are grateful to the custodians of the soil site data in each state and territory for providing access to the soil site data, and all of the organisations listed as collaborating agencies for their significant contributions to the project and its outcomes. We thank also D. Jacquier and P. Wilson for their inputs.

1181.2 TERN Facility No9 InfoGrid GRUNDY
The Soil and Landscape Grid of Australia is a comprehensive fine spatial resolution grid of functional soil attributes and key landscape features across Australia. The landscape attributes are derived from the data collected by the Shuttle Radar Topography Mission, whilst the soil attribute surfaces are modelled from existing soils information. The... morese surfaces provide a consistent base upon which a broad range of analyses can be conducted. This provides essential information, not previously available, that is needed for modelling and managing Australian landscapes and ecosystems. less
National Soil Grid
The Soil and Landscape Grid of Australia Facility has produced a comprehensive fine-resolution grid of soil attributes and important land surface parameters. The data is consistent with the Specifications of the GlobalSoilMap and is managed as part of the Australian Soil Resource Information System (ASRIS). There are a range of soil attribute produ... morects available from the Soil Facility. Each soil attribute product is a collection of six fine spatial resolution (3 arc sec) digital soil property maps, one for each of the standard depths, and each with an upper and lower confidence limits, provided in raster format. less
