Description
This polygon dataset describes the land resources of Umbeara Station, occupying an area of 3,600 km2, located approximately 200 km south of Alice Springs.
The land resource survey was undertaken in 2002 at a scale of 1:100,000. Fifty three land units have been identified and mapped on the station for the purpose of assisting with land management decision-making on the property. Each land unit is provided with a detailed description in terms of its landform, soil and vegetation characteristics. The report includes the pastoral land management implications of these attributes.
Core attributes describing the land units, as defined by this department, were added to the spatial dataset in October 2020. A new map product was created for this survey.

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 compiled via geographic information system (ESRI ArcGIS / MapInfo). Core landform, soil and vegetation attributes attached to the polygon 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 SOURCE DATA
Site point coordinates derived from a geographic positioning system with general accuracy of within 10-50m.
Attribute Accuracy:The attribute information conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture.
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. The department has assigned a list of core attribute values, described in the Data Dictionary below, to each polygon.
The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format.
Core attributes describing the land units, as defined by this department, were added to the spatial dataset in October 2020.
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
Attribute Attribute Description Possible Code Code Description 01. SURVEY_NME Alias: Survey Name
The name of the survey area or report to which the mapping refers.02. SURVEY_ID Alias: Survey Identifier
A department code that usually refers to the first five characters from the original survey site sheet.03. LANDUNIT Alias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (ie 9a2).04. 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).05. SOIL_SYS Alias: Soil Classification System
The soil classification system used to describe the soil in the land unit description.06. SOIL Alias: Dominant Soil Order
The dominant soil order described in a land unit is recorded.07. VEG_SYS Alias: Veg Classification System
The National Vegetation Information System (NVIS) classification system.08. VEG_STRUC Alias: Dominant Veg Structure
Vegetation structural classes from NVIS (ESCAVI 2003), Walker and Hopkins (1998) and Specht (1970) classification schemes.09. SPECIES_1 Alias: Veg Dom Species 1
The dominant vegetation species described in a land unit. The order of species listed determines their dominance.10. SPECIES_2 Alias: Veg Dom Species 2
Where 2 dominant vegetation species were described in a land unit. The order of species listed determines their dominance.11. SPECIES_3 Alias: Veg Dom Species 3
Where 3 dominant vegetation species described in a land unit. The order of species listed determines their dominance.12. 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.13. 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.14. 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.
