Description

Abstract:

This spatial dataset describes land unit polygons for landform, soils and vegetation to assist with land management decisions for the property Alroy Downs Station, NT Portion 651. The survey area of 4200km2 is located approximately 180km north/east of Tennant Creek on the Tablelands Highway. The land unit survey was undertaken in 1992 at a scale of 1:100,000.

The department's set of core land unit attributes were added to this dataset in September 2013.

Data Quality

Lineage:Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to topographic map sheets 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). Core landform, soil and vegetation attributes attached to map units with additional attributes unique to individual surveys.

Positional Accuracy:POLYGON DATA
Map unit boundaries transferred from aerial photographs to topographic maps, using the best available topographic mapping at the time (generally 1:100 000) via a mapograph. 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 moderate to high.
POINT DATA
Site point coordinates collected from a geographic positioning system with general accuracy of within 100m. Selective availability during this time prevented increased accuracy.

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. Core attribute values, as described in the Data Dictionary below, were added to each polygon in September 2013.

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

Data Dictionary

Attribute Attribute Description Possible Code Code Description

LAND_UNIT Alias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (ie.9a2).

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).

LU_DESC Alias: Land Unit Description
The LU_DESC is a general text field from the map legend. The amount of detail may vary between surveys.

SOIL Alias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.

SOIL_SYS Alias: Soil Classification System
The soil classification system used to describe the soil in the land unit description

SPECIES_1 Alias: Veg Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.

SPECIES_2 Alias: Veg Species 2
Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance.

SPECIES_3 Alias: Veg Species 3
Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance

SURVEY_ID Alias: Survey Identifier
Usually refers to the first five characters from the corporate survey code.

SURVEY_NME Alias: Survey Name
The full name of the report to which the mapping refers

VEG_STRUC Alias: Dominant Veg Structure
Vegetation structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes

VEG_SYS Alias: Veg Classification System
The National Vegetation Information System (NVIS) classification system.
