The survey area of 9.3 ha was mapped at a scale of 1:5,000 in February 2017. Core attributes describing the land units, as defined by this department, have been added to the spatial polygons.

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.0Map unit boundaries delineated from digital satellite imagery (WorldView-2) and digital elevation model (SRTM-derived 1 second Smoothed DEM). Preliminary line work was captured on field map sheets. Field map sheets incorporated digital satellite imagery and DEM layers. Field map sheets with final line work were scanned and rectified. Line work was 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.
