Description

Abstract:

Soil and Land Assessment of the Southern Part of Flying Fox Station for Irrigated Agriculture. Part A: Land Resources and General Land Capability.
Department survey code ROPLU_100
The field survey was undertaken at a mapping scale of 1:100,000.

This spatial dataset provides polygon information delineating land unit boundaries at a scale of 1: 100 000 and describes the dominant landform, soils and vegetation of the southern part of Flying Fox Station, Northern Territory. The study area covers 53,000 ha. and is located approximately 190 km south-west of the Katherine township via the Stuart and Roper Highways.
The primary purpose of the investigation was to map, describe and evaluate soil landscapes to inform future irrigation development in an area with identified potential for groundwater extraction. Core landform, soil and vegetation attributes attached to the land units are included with the spatial dataset.

In addition to the traditional land unit polygons, the study area developed raster data describing crop suitability using Digital Soil Mapping (DSM) software described in a separate report, Part B: Digital Soil Mapping and Crop Specific Land Suitability. This report is described in the metadata record, www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=861088D6EE01EFD9E050CD9B21441AD5.

Data Quality

Lineage:Map unit boundaries delineated from digital satellite imagery (WorldView-2) and digital elevation model (SRTM-derived 1 second Smoothed DEM). Preliminary linework was captured on field map sheets. Field map sheets incorporated digital satellite imagery and DEM layers. Field map sheets with final linework were scanned and rectified. Linework digitised on screen directly from field map sheets.
Map unit boundaries derived using digital satellite imagery, DEM, 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 digitised on screen directly from digital rectified field maps. Level of accuracy depends on the number of control points on individual map sheets. Control points exclusively used Map Grid of Australia (MGA) grid lines. 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 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 were 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 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.

The department has assigned a list of attributes to each polygon, described in the Data Dictionary below.
In addition to these core attributes, the spatial data also contains information about general land capability. The assessment evaluates 10 landscape characteristics that could influence the general use of the land: acid sulfate, flooding, microrelief, salinity, sodicity, soil depth, soil drainage, surface rock and wind erosion.

Each attribute has been defined using a class. Refer to the report in Chapter 8 and Appendix 4 for further details and definitions.

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.

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 LAND_UNIT 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
