The survey aimed to refine existing Henbury Land System mapping (Bastian 1983) and improve soil property descriptions. The survey area of 5,300 km2 is located approximately 120 km south-west of Alice Springs via the Stuart Highway. 79 field sites were described during July - September 2020, including 17 with laboratory analysis. The spatial data has a mapping scale of 1:250,000.Download the spatial data package via https://data.nt.gov.au/ You are licensed to use the geospatial products on the terms and conditions set out in: Creative Commons Attribution 4.0 International Public License (CC BY 4.0) at: https://creativecommons.org/licenses/by/4.0/legalcode.

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 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.0- 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 (ESRI ArcGIS). Attributes attached to map units with additional attributes unique to individual surveys.
