Description
This polygon spatial dataset provides information on the land unit boundaries of Woolaning Community, Northern Territory and describes dominant landform, soils and vegetation. The survey area of 7.13 km2 is located approximately 120 km south of Darwin. The dataset from derived from Land Resources of Litchfield National Park (reference LU: TTRAN_50).
The original field survey was undertaken in 1988 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 February 2023.

Data Quality
Lineage:Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to clean dyeline sheets via a Mapograph reflector projector and were interpreted by a land assessment officer in 2023 at 1:50,000. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by rectifying the original hard copy maps.
Original dyeline sheet was scanned as a one bit TIFF file. Within ARCMAP the raster data was then cleaned up using ARCSCAN. The cleaned raster was georeferenced then vectorized.
Field data (site data) described and classified according to national standards at the time of capture.
Map unit polygons collected via geographic information system (ESRI ArcGIS). Core landform and soil attributes attached to map units with additional attributes unique to individual surveys.
Positional Accuracy:POLYGON DATA
Scanned map georeferenced using control points marked on original hardcopy maps. Control points include creek lines, drainage systems 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. The department has assigned a list of core attribute values, described in the Data Dictionary below, to each polygon.
The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format.
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
Attribute Attribute Description Possible Code Code Description 01 SURVEY_NME Alias: Survey Name
The name of the survey area or report to which the mapping refers.
02 SURVEY_ID Alias: Survey Identifier
A department code that usually refers to the first five characters from the original survey site sheet.
03 LAND_UNIT Alias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (ie 9a2).
04 LF_CLASS Alias: 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 et.al. 1998).
05 SOIL_SYS Alias: Soil Classification System
The soil classification system used to describe the soil in the land unit description.
06 SOIL Alias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.
07 VEG_SYS Alias: Veg Classification System
The National Vegetation Information System (NVIS) classification system.
08 VEG_STRUC Alias: Dominant Veg Structure
Vegetation structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes.
09 SPECIES_1 Alias: Veg Dom Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.
10 SPECIES_2 Alias: Veg Dom Species 2
Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance.
11 SPECIES_ 3 Alias: Veg Dom Species 3
Where 3 dominant vegetation species described in a land unit. The order of species listed determines their dominance.
12 LF_DESC Alias: Landform Description
Landform description includes details about landform, and general notes pertaining to slope, surface gravel and other details describing the land unit.
13 SOIL_DESC Alias: Soil Description
Soil description includes an ASC or Northcote/other soil classification and usually includes colour, soil depth and other notes describing the soil.
14 VEG_DESC Alias: Vegetation Description
The dominant species and its structure are recorded. Occasionally it will include minor vegetation communities also noted in the land unit description and/or notes specific to the community.
15 AREA_HA Alias: Area (ha)
Total area in hectares is included for each map unit.
