Description

Abstract:

This polygon spatial dataset describes the land resources of Delny / Delmore Downs Station, occupying an area of 1 220 sq km, located approximately 230km north-east of Alice Springs. Thirty-six land units have been identified and mapped on the station for the purpose of assisting with land management decision-making on the property. The technical report describes the land units in terms of its landform, soil and vegetation characteristics and includes the pastoral land management implications of these attributes.

The original field survey was undertaken in 1989 at a mapping scale of 1:100,000. Core attributes describing the land units were added to the polygon spatial dataset in February 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 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. 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.

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 related text field from the map legend. The amount of detail may vary between surveys.
SOILAlias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.
SOIL_DESCAlias: Soil Description
Soil related text field from the map legend. The amount of detail may vary between surveys
SOIL_SYSAlias: Soil Classification System
The soil classification system used to describe the soil in the land unit description
SPECIES_ 3Alias: Veg Dom Species 3
Where 3 dominant vegetation species described in a land unit.The order of species listed determines their dominance
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 were 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 full name of the report to which the mapping refers
