Soil and Landscape Grid National Soil Attribute Maps - Soil Colour (3" resolution) - Release 1

We used Digital Soil Mapping (DSM) technologies combined with collations of observed soil colour data from TERN's Soil Data Federation System, to produce surface and subsoil maps of soil colour at a 90m resolution.

The map gives an estimate of the spatial distribution of RGB soil colour across Australia.
