Description
This spatial dataset describes the polygon information on the map unit boundaries on the Dry River and Willeroo (part of) pastoral leases, Northern Territory. The land resource survey was conducted in May of 1974 at a scale of 1:100,000 and covers an area of approximately 2,108km2 - located on the western part of the Sturt Plateau; some 100km south of Katherine along the Victoria Highway. The survey mapped and described 18 land systems on the properties providing information about soil, vegetation and landform.
In 2011, the department reassessed this survey and broadened the survey scale to 1 : 250,000.
This spatial dataset was amalgamated within the compilation dataset Land System Surveys of the Northern Part of the Northern Territory. (Department survey code NORTH_250)

Original 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, geological and topographic maps. Field data (site data) described and classified according to national standards at the time of capture.
Map unit polygons created via geographic information system 2001 and further refined in 2011.
Positional Accuracy:POLYGON DATA
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 DATA
Survey teams navigated during field operations with topographic maps, aerial photographs and prismatic compass. 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 via Geographic Information System software.
Attribute Accuracy:Attributes 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.
The attributes for each polygon in this spatial dataset are minimal. Further detail about each mapunit / land system is described in the associated report.
Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work, nodes are formed at the intersection of lines, polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.
