Custodian: Department of Environment and Natural Resources



A preliminary land, water and biodiversity investigation in late 2013 identified several areas across the Tiwi Islands as potentially suitable for agricultural land. The area targeted for detailed survey was selected in collaboration with other Northern Territory Government departments and traditional owners.

The resulting study area targeted an area of 14 000 ha on north east Bathurst Island. The associated technical report describes the bio-physical resources for the study area, including; geology, geomorphology, groundwater, surface water, land resources, flora, fauna and crop suitability.

This polygon spatial dataset provides information on the land unit boundaries of North East Bathurst Island, Northern Territory, and describes dominant landform, soils and vegetation. The survey area is located approximately 125 km north west of Darwin.

The field survey was undertaken in 2014 at a mapping scale of 1:25,000. Core attributes describing the land units, as defined by this department, were also compiled as part of this spatial dataset.

Data Quality

Lineage: Map unit boundaries delineated from aerial photographs. Aerial photography scanned and rectified. Linework digitised on screen directly from original aerial photographs.
Map unit boundaries derived using aerial photography and digital satellite imagery, geological and topographic data. Field data (site information) described and classified according to national standards at the time of capture.
Map unit polygons collected via geographic information system (ArcGIS/MapInfo). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.

Positional Accuracy: POLYGON DATA - Map unit boundaries digitised on screen directly from digital rectified aerial photographs. Level of accuracy depends on the number of control points on individual aerial photographs. 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 high to very high.
POINT DATA - Site point coordinates derived from a geographic positioning system with general accuracy of within 10-50m.

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.

Additional attributes have been assigned to this polygon dataset including descriptions for; Slope, Soil Depth, Rock Outcrop, Drainage, Erosion Rick, Acid Sulfate Presence, Sensitive Habitat Presence and Agricultural Suitability.

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
DOUBLE_LABAlias: Land Unit Other Component
Used where a land unit label shares 2 descriptions. (field only used when relevant)
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).
LF_DESCAlias: Landform Description
Landform description includes details about landform, and general notes pertaining to slope, surface gravel and other details describing the land unit.
SOILAlias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.
SOIL_DESCAlias: Soil Description
Soil description includes an ASC or Northcote/other soil classification and usually includes colour, soil depth and other notes describing the soil.
SOIL_SYSAlias: Soil Classification System
The soil classification system used to describe the soil in the land unit description
SPECIES_1Alias: Veg Dom Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.
SPECIES_2Alias: Veg Dom Species 2
Where 2 dominant vegetation species are described in a land unit. The order of species listed determines their dominance.
SPECIES_3Alias: Veg Dom Species 3
Where 3 dominant vegetation species are described in a land unit. The order of species listed determines their dominance.
SURVEY_IDAlias: Survey Identifier
A department code that usually refers to the first five characters from the original survey site sheet.
SURVEY_NMEAlias: Survey Name
The name of the survey area or report to which the mapping refers
VEG_DESCAlias: 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.
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.
