What is the level of uncertainty: percent clay, point model (topsoil and subsoil)?
The model for percent clay in topsoil is generally good, although it is strongest in Queensland, Victoria and Tasmania and less reliable in southern New South Wales, Northern Territory and Western Australia. This is considered to be a more reliable estimate of percent clay than that produced by the polygon-based model. The subsoil model is much less reliable, as indicated by the error diagnostics. It is weakest in New South Wales, Western Australia, South Australia and Northern Territory.
