Part A: Land Resources and General Land Capability. 2021-03-03Soil 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, http://www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=861088D6EE01EFD9E050CD9B21441AD5.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownPolygon 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.0not knownThe 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.0Map 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.
