Description

Abstract:

This spatial dataset delineates Land Units at a scale of 1:100 000 over approximately 10,402 km2 within the Western Davenport region, covering the complete areas of Neutral Junction pastoral lease and Murray Downs pastoral lease to better inform future land resource management. Dominant landform, soils and vegetation are described for each Land Unit, and general land capability is assessed.
The assessment is considered for Mapping the Future project for the Western Davenport Water Allocation District.

Data Quality

Lineage:Map land unit boundaries delineated from interpretation of previous land resource survey linework; historic aerial photography; satellite imagery including ESRI World Imagery, Google Satellite Imagery, Sentinel-2 imagery; NTGS Airborne Magnetic and Radiometric Survey; and SRTM-derived (Shuttle Radar Topographic Mission) 1 second (~30m) Digital Elevation Model.
Field data described and classified according to national standards at the time of capture. Final map unit boundaries adjusted to account for field data. Core landform, soil and vegetation attributes attached to map units.
Spatial data formats are ESRI file geodatabase and shapefiles. Data is stored in datum GDA94, geographics.

Positional Accuracy:Polygon data - map unit boundaries delineated on screen using geographical information system software at a scale of 1:100 000. Positional accuracy generally considered to be moderately high.

Attribute Accuracy:The attribute information conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture. Survey methodologies and related technical assessments used during the investigation are listed in the accompanying technical report:
Mapped land units typically exhibit a uniform pattern on aerial photography or satellite imagery, and present as a repeatable and recognisable combination of landscape terrain, soil type and associated vegetation community. While some degree of variation is normally expected within a land unit, such variation is usually too small or too inconsistent to map separately at the given survey scale. 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's list of core attribute values, described in the Data Dictionary below, have been added to each polygon.
Each land unit has also been assessed for GENERAL LAND CAPABILITY, evaluating landscape characteristics that could influence the general use of the land. A General Land Capability Class of 1 Land with negligible constraints to Class 4 Land with Extreme Constraints has been assigned to each land unit. Descriptions for key characteristics considered important have been added to the land unit polygon, including flooding, slope (as a surrogate for water erosion), soil depth, soil drainage, surface rock, and wind erosion.

Logical Consistency:GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon topology rules applied include: must not overlap and must not have gaps.

Attribute Attribute Description Possible Code Code Description

FLOODING Alias: Capability Class - Flooding
Assessment criteria use estimates of Average Recurrence Interval (ARI), to gauge the regularity and severity of potential flood events. Estimated values have been aligned with recognisable alluvial landforms as a surrogate for ARI where suitable modelled data is unavailable. 1 Flood free

2 Extremely rare: <1 in 30 years

3 Rare: 1 in 10-30 years

4 Regular to permanent: >1 in 10 years

LAND_UNIT Alias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (i.e. 8k2_1).

LCAP_CLASS Alias: Capability Class - General Land Capability
General land capability assessment evaluates key land unit characteristics to determine the broad capability of an area for sustainable development. The assessment classifies land on the basis of ten key attributes, with final land capability class is determined by the most constrained attribute. It is not land use or development specific, and does not consider or address individual project requirements, land management practices or potential mitigation strategies. 1 Land with negligible constraints that require only a basic level of inputs, expertise and investment to develop and manage the land sustainably.

2 Land with minor or moderate constraints that require a greater level of inputs, expertise and investment than Class 1 to develop and manage the land sustainably.

3 Land with severe constraints that require that require a high level of inputs, expertise and investment to develop and manage the land sustainably.

4 Land with extreme constraints that generally require an unacceptable level of inputs, expertise and investment to develop and manage the land sustainably; making it either impractical, uneconomic or environmentally unsound to proceed.

LCAP_DESC1 Land Capability Description 1

LCAP_DESC2 Land Capability Description 2

LF_CLASS Alias: Landform Class
Landform class is a system adopted by the department. The categories do not completely conform to national criteria even though most are sourced from Australian Soil and Land Survey - Field Handbook (NCST, 2009).

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.

SLOPE Alias: Capability Class - Slope
Assessment criteria use accepted slope gradient (%) limits defined in the Northern Territory Land Clearing Guidelines (DEPWS 2021), as a surrogate for estimating erosion risk. 1 Low erosion risk: 0-1% slope gradient

2 Moderate erosion risk: 1-2% slope gradient

3 High erosion risk: 2-3% slope gradient

4 Very high erosion risk: >3% slope gradient

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

SOILDEPTH Alias: Capability Class - Soil depth
Assessment criteria are based on standard depth categories (very shallow to very deep) from the Australian Soil Classification (Isbell and NCST 2021). 1 Deep to very deep: >1.0 m

2 Moderately deep: 0.5-1.0 m

3 Shallow: 0.25-0.5 m

4 Very shallow: <0.25

SOILDRAIN Alias: Capability Class - Soil drainage
Assessment criteria are based on the soil drainage classes defined by the Australian Soil and Land Survey - Field Handbook (NCST, 2009). Assessment considers both internal soil profile characteristics and external landscape factors that collectively contribute to excessive soil wetness. 1 Rapidly to well drained

2 Moderately well drained

3 Imperfectly drained

4 Poorly to very poorly drained

SOIL_DESC Alias: Soil Description
Soil description includes classification information and usually includes colour, soil depth and other notes describing the soil.

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

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

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.

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.

SURFROCK Alias: Capability Class - Surface rock
Assessment criteria are based on the combined abundance of surface in-situ rock outcrop, in addition to cobbles (60-200 mm), stones (200-600 mm) and boulders (600- 2,000 mm) (NCST 2009) 1 Nil: 0%

2 Minor: 0-2%

3 Moderate: 2-10%

4 Severe: >10%

SURVEY_ID Alias: Survey Identifier
A department code that usually refers to the first five characters from the original survey site sheet.

SURVEY_NME Alias: Survey Name
The name of the survey area or report to which the mapping refers

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 Alias: Dominant Vegetation Structure
The dominant vegetation structure as described in a land unit.

VEG_SYS Alias: Vegetation Classification System
The classification system used to describe the vegetation in the land unit description

WIND_EROS Capability Class - Wind erosion
Assessment criteria are based on a two-step method (van Gool et al., 2005) to determine a wind erosion susceptibility class:
1. Inherent erodibility - estimate of percent surface cover of coarse fragments (0-20%, 20-50%, 50-100%) and surface condition; and
2. Wind erosion susceptibility - allocation of landform category. 1 Low hazard

2 Moderate hazard

3 High hazard

4 Very high to extreme hazard
