Description
This polygon spatial dataset provides information on the land unit boundaries of Wagait Aboriginal Reserve Area, Northern Territory and describes dominant landform, soils and vegetation. The survey area of 1,424 km2 is located approximately 70km south-west of Darwin. The purpose of the survey was to determine the suitability of the Reserve for agricultural and pastoral enterprises.
The original field survey was undertaken in 1973 at a mapping scale of 1:50,000. Core attributes describing the land units were added to the spatial dataset in February 2014.

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 (ARC/MapInfo). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.
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 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.
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.
Completeness:Complete.

Attribute Attribute Description Possible Code Code Description LAND_UNIT The LAND_UNIT field is the land unit label from the spatial dataset (ie.9a2). LF_CLASS Landform class is a system adopted by the department. The categories do not conform to national criteria even though some have been sourced from Australian Soil and Land Survey - Field Handbook (Mc Donald et.al. 1998). LF_DESC The LF_DESC is the landform related text field from the map legend. The amount of detail may vary between surveys. LU_DESC The LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys SOIL_DESC The SOIL_DESC is the soil related text field from the map legend. The amount of detail may vary between surveys. SOIL_SYS The SOIL_SYS field is the soil classification system used to describe the soil in the land unit description SPECIES_ 3 Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance SPECIES_1 The dominant vegetation species described in a land unit. The order of species listed determines their dominance SPECIES_2 Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance SURVEY_ID The SURVEY_ID field is the first five characters from the corporate survey code SURVEY_NME The SURVEY_NME is the full name of the report to which the mapping refers VEG_DESC The VEG_DESC is the vegetation related text field from the map legend. The amount of detail may vary between surveys. VEG_STRUC Structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes VEG_SYS The National Vegetation Information System (NVIS) classification system
