The survey area of 2,215 km2 is located approximately 140 km north of Alice Springs on the Sandover Highway. The name, Atartinga Station, was also used as a local reference for the property. The polygons were created using satellite imagery classification with limited field survey work undertaken in 1988. The spatial data should not be used beyond a mapping scale of 1:100,000. Core attributes describing the land units, as defined by this department, were added to the spatial dataset in November 2015.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownDerived from LandSat5 TM imagery, GPS and NT cadastre. The summation of errors from all sources results in data with a standard deviation defined by scale used as +/-250m for well-defined points.0not knownAlthough limited fieldwork was conducted in 1988, the extensive local knowledge of the landholder (Bob Purvis) was incorporated in the mapping process resulting in a attribute information rating that is considered high and conforms to the 'Australian Soil and Land Survey Field Handbook' at time of capture. Attribute values, as described in the Data Dictionary below, have been added to each polygon.0Original linework derived using satellite image classification to delineate land unit boundaries and site selection. The original image was stratified into broad land types based on initial image interpretation, local knowledge and ground truthing. Supervised classification within each of these strata was conducted using training classes which aimed to capture the diversity of spectral responses for that strata. The resulting classified image with labelled units representing the ground truthed vegetation types was plotted from ERMapper with a legend containing landscape photographs of each class. ArcInfo GRID was used to simplify the classified raster data, (which had many small areas of only a few pixels in size) resultant grid dataset converted into a ArcInfo vector polygon coverage AGD66, then further processed to reduce the number of polygons and produce the final coverage. The spatial data was projected to geographics, datum GDA94 in 2005. Source data: Satellite image - LandSat5 TM 18/12/1996 / Path / Row 7 / Q Scene / Bands 1 to 5
