Description

Abstract:

This polygon spatial dataset provides information on the land unit boundaries of Erldunda Station, Northern Territory and describes dominant landform, soils and vegetation. The survey area of 2990km2 is located approximately 200km South-west of Alice Springs on the Stuart Highway.

The original field survey was undertaken in 1998 at a mapping scale of 1:100,000.
Core attributes describing the land units, as defined by this department, were added to the spatial dataset in October 2014.

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 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 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 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.

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

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 et.al. 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 described in a land unit. The order of species listed determines their dominance.
SPECIES_3Alias: Veg Dom Species 3
Where 3 dominant vegetation species 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_SYSAlias: Veg Classification System
The National Vegetation Information System (NVIS) classification system.
