Description

Abstract:

This polygon spatial dataset provides information on the land unit boundaries of Murray Downs Station, Northern Territory. The spatial data describes each of the twenty six land units in terms of landform, soils and vegetation attributes and indicates the possible implications of pastoral land use on both soil stability and pasture growth. The survey area of 5600 km2 is located approximately 300 km north of Alice Springs.
The original field survey was undertaken in 1988 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 May 2017.

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: 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 geo-referenced 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.

Completeness:Complete

Attribute Attribute Description Possible Code Code Description

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

LF_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_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.

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.

SOIL_SYS The SOIL_SYS field is the soil classification system used to describe the soil in the land unit description

SPECIES_ 3 Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance.

SPECIES_1 The dominant vegetation species described in a land unit. The order of species listed determines their dominance

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

SURVEY_ID The SURVEY_ID field is the first five characters from the corporate survey code.

SURVEY_NME The SURVEY_NME is the full name of the report to which the mapping refers

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.

VEG_STRUC Structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes
