The survey area of 475km2 is located approximately 250km south of Katherine on the Sturt Plateau via the Stuart Highway.
70 sites were described in the original field survey undertaken in 1982-1983 at a mapping scale of 1:50,000.
Core attributes describing the land units, as defined by this department, were added to the spatial dataset in September 2014.

Hardcopy maps rectified using control points marked on original hardcopy maps. Control points include creek lines, cadastre and other topographic features. Depending on the nature of the landscape (the number of control points) positional accuracy may vary. Positional accuracy generally considered moderate.
POINT SOURCE DATA
Survey teams navigated during field operations with topographic maps, aerial photographs and prismatic compass's. Point source locations marked on aerial photography in the field. Positional accuracy considered within 300m but generally below 200m depending on the terrain. Site coordinates derived by transferring site locations from aerial photographs to topographic maps and coordinates calculated. In some cases sites have been georeferenced directly from aerial photography to Google Earth Web Map Server in MapInfo or ArcGIS.0not knownAttributes assigned according to the dominant feature. For example, where ten sites have been grouped to describe a particular map unit and two different soils described from these sites then the dominant soil is chosen. Attribute values, as described in the Data Dictionary below, have been added to each polygon.0Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to clean dyeline sheets or topographic maps via a mapograph. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by rectifying the original hard copy maps.
Map unit boundaries derived using hard copy aerial photography and stereoscope, satellite imagery (post 1993), geological and topographic maps. Field data (site data) described and classified according to national standards at the time of capture.
Map unit polygons collected via geographic information system (ARC/MapInfo). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.
