SA-format soil and land attributes

SA-format soil and land attribute datasets describe key characteristics relating to distinct elements in the landscape, also known as ‘landscape components’ (e.g. flats, rises, swales, sandhills). Over forty attributes of importance for land use and natural resource management are ascribed to these landscape components. One of these attributes denotes the presence of distinctive soils (termed ‘subgroup soils’ in the reference text Hall et al. 2009) associated with each landscape component.

SA-format datasets have been developed via the State Land and Soil Mapping Program, based on criteria contained within Maschmedt 2002, and are available for viewing on NatureMaps and download via Data.SA.
