Soil and Landscape Grid National Soil Attribute Maps - Depth of Regolith (3" resolution) - Release 2 

This is Version 2 of the Depth of Regolith product of the Soil and Landscape Grid of Australia (produced 2015-06-01).

The Soil and Landscape Grid of Australia has produced a range of digital soil attribute products. The digital soil attribute maps are in raster format at a resolution of 3 arc sec (~90 x 90 m pixels).

• Attribute Definition: The regolith is the in situ and transported material overlying unweathered bedrock;
• Units: metres;
• Spatial prediction method: data mining using piecewise linear regression;
• Period (temporal coverage; approximately): 1900-2013;
• Spatial resolution: 3 arc seconds (approx 90 m);
• Total number of gridded maps for this attribute: 3;
• Number of pixels with coverage per layer: 2007M (49200 * 40800);
• Data license : Creative Commons Attribution 4.0 (CC BY);
• Variance explained (cross-validation): R^2 = 0.38;
• Target data standard: GlobalSoilMap specifications;
• Format: Cloud Optimised GeoTIFF;

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. These 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.
