Dataset Number 1277 Dataset Title Soil Groups Custodian Data Authority: Department for Environment and Water Data Provider: Department for Environment and Water

Description Description 15 broad Soil Groups (groupings of 61 Soils (soil type)) have been identified, representative of the range occurring across southern South Australia, based on an interpretation of Soil Landscape Map Units. 15 Soil Group and 3 miscellaneous attribute (or 'analysis data') classes have been supplied, as percentage (areal extent) values of each Soil Group within each Soil Landscape Map Unit. Note: the sum of all percentage values for each map unit totals 100%. This analysis data is to be used for the creation of spatial data statistics. For map display purposes, the most commonly occurring Soil Group (SOIL_GROUP legend category) is defined, however, it should be noted that this often accounts for less than 50% of a Soil Landscape Map Unit. Usage Link to Soil Attribute Descriptions. This dataset has been derived from the Soil Landscape Map Units spatial dataset to be used for map creation or the calculation of spatial data statistics. Used to supply Government, community groups, industry and the general public with up to date regional, subregional and catchment level land and soil attribute information for southern South Australia. The aim is to produce maps, statistics and reports displaying and describing: Land and soil attributes within southern South AustraliaSELECT 1 FROM DUAL; Land surface features affecting land use, land management and productivitySELECT 1 FROM DUAL; Limitations / suitability of land and soil for a range of agricultural and other uses. Independent professional advice should be sought before using this in commercial decisions. Further information: soil and land attributes. Soils Groups dataset can be viewed at NatureMaps (>Soils>Soil Type Attributes). Spatial data downloads are available from Data SA.

Data Quality Lineage The dataset is based on an interpretation of 1:40,000 stereo colour aerial photography and limited field inspection of landscapes and soils by soil scientists. Soil Landscape Map Unit boundaries were determined after an integration of field observations and recordingsSELECT 1 FROM DUAL; laboratory analysesSELECT 1 FROM DUAL; stereoscopic examination of aerial photographsSELECT 1 FROM DUAL; understanding of regional landscape processes and stratigraphySELECT 1 FROM DUAL; existing soil and geological mapping data. To avoid inconsistencies and confusion, any updates to the Soil and Land Attribute mapping are to be managed by DEWNR Soil and Land Program. This data has been released under a Creative Commons licence. Where products are derived from this data, DEWNR are to be acknowledged, and any changes to the original data should be indicated. Completeness Complete. The spatial data is subject to amendment as and when more data become available. Positional Accuracy The accuracy is to the scale of mapping (50 metres at 1:50,000 and 300 metres at 1:100,000 mapping scale). The spatial data is to be used at the regional, subregional and catchment level, and can be used to provide property overviewsSELECT 1 FROM DUAL; however, cannot be used at the paddock level. South East, Kangaroo Island, Mount Lofty Ranges and the 'bottom' of Yorke Peninsula have been mapped at 1:50,000. Eyre Peninsula, the main part of Yorke Peninsula, Murray Mallee and Northern Agricultural Districts have been mapped at 1:100,000. Map unit boundaries should be treated as transition zones.
