Data Title

Soil Hydrological Properties for Australia

Custodian

Jurisdiction

Description Abstract This data set provides soil hydrologic properties for A and B horizons derived from soil mapping, a database of typical soil properties and pedotransfer functions. The mapping is based on the Atlas of Australian Soils. Soil properties provided include solum depth, solum plant available water holding capacity, A horizon thickness, A horizon saturated hydraulic conductivity (ksat), A horizon ksat uncertainty estimate, A horizon porosity, A horizon field capacity, A horizon wilting point, A horizon plant available water holding capacity, proportion of area with a B horizon, and the same properties for the B horizon as provided for the A horizon.

Data Quality Lineage

Source data for this data set include the Digital Atlas of Australian Soils from the Bureau of Rural Sciences and estimates of soil properties from McKenzie, N.J., Jacquier, D.W., Ashton, L.J. and Cresswell, H.P., 2000, Estimation of soil properties using the Atlas of Australian Soils, Technical Report 11/00, CSIRO Land and Water, Canberra.

 
Positional Accuracy

The predictive surface is a 0.01 X 0.01 degree grid (geographic coordinate system) or 1 X 1 km (Map Grid of Australia projections). The mapping is derived from a 1:2,000,000 scale representation of polygons originally mapped at 1:250,000 and 1:500,000 scales. Mapping detail varied between regions.

Attribute Accuracy

The attribute accuracy is highly variable. Information on the level of data support and reliability is provided with the estimates. The number of data points used to estimate properties for specific soil types is quite variable and often low. Area weighted averaging was required to transfer McKenzie et al?s (2000) estimates of soil properties for specific soil types (principle profile forms) to estimates for mapped soil landscapes. These resulting estimates provide a regional scale pattern of variation and should not be used for small scale applications or where high attribute accuracy is required.

Logical Consistency

The data is logically consistent in that each value in the map relates to a single value in the property database.

Completeness

The data is more than 99% complete.

Additional Metadata Additional Metadata

A more detailed user guide is part of this data set. McKenzie et al. (2000) (available from http://www.clw.csiro.au/publications/technical2000/) describe the development of estimates of the properties of principle profile forms and the common principle profile forms found in each soil landscape represented in the Atlas of Australian Soils. The Digital Atlas of Australian Soil (Bureau of Rural Sciences after Commonwealth Scientific and Industrial Research Organisation, 1991) is described in the meta data for that product (The user guide is no longer available. The Bureau of Meteorology now handles this).
