This spatial dataset provides polygon information on the map unit boundaries of the Land Units of the Woolner Area, Northern Territory. The survey was undertaken in 1971 covering an area of 192km2. The survey area is located on the coastal plains approximately 60km east of Darwin on the property Woolner, NT Portion 1299.
A technical report was not written at the time to describe this survey and data, however a map and legend was compiled.

Core attributes describing the land units were added to this spatial data set in September 2013.

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.

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.

Data Dictionary

AttributeAttribute DescriptionPossible CodeCode Description
LAND_UNITAlias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (ie.9a2).
LF_CLASSAlias: Landform 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 1998).
LU_DESCAlias: Land Unit Description
The LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys.
SOILAlias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.
SOIL_SYSAlias: Soil Classification System
The soil classification system used to describe the soil in the land unit description
SPECIES_1Alias: Veg Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.
SPECIES_2Alias: Veg Species 2
Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance.
SPECIES_3Alias: Veg Species 3
Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance
SURVEY_IDAlias: Survey Identifier
Usually refers to the first five characters from the corporate survey code.
SURVEY_NMEAlias: Survey Name
The full name of the report to which the mapping refers
VEG_STRUCAlias: Dominant Veg Structure
Vegetation structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes
VEG_SYSAlias: Veg Classification System
The National Vegetation Information System (NVIS) classification system
