This polygon spatial dataset provides information on the land unit boundaries of the Kilfoyle Plains within the Lower Daly River Region, Northern Territory and describes dominant landform, soils and some vegetation. The survey area of 1,421 km2 is bisected by the lower Daly River and is located between the community of Nauiyu to the northern side of the mouth of the Daly.

The original field survey was undertaken between 1965 and 1967 at a mapping scale of approximately 1:30,000 to complement other investigations for the irrigation potential of the area. This spatial dataset contains only a minimal set of attributes describing the land units.

Data Quality

Lineage: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, 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 (ArcGIS/MapInfo).

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 to Google Earth Web Map Server in MapInfo or ArcGIS.

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. Attribute values, as described in the Data Dictionary below, have been added to each polygon.

Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.
