Data Quality

Lineage: The aquifer thickness, depth to water table below ground level, water levels and groundwater salinity boundaries were derived from geology maps, topographic maps, aerial photographs and stereoscope interpretation and satellite imagery interpretation.
The hydrology information from standing water level measurements flows from springs, chemical analysis of groundwater samples and surveys of outcrops of recharge beds.

The core attributes information associated with the aquifer thickness, depth below ground level of the water table and groundwater salinity dataset was derived from the original map's legend and annotations. File name Ti-Tree-Basin_GWater_m53.dgn.

Positional Accuracy: Positional accuracy of 250 metres from bore locations.

Attribute Accuracy: Attributes assigned according to the dominant feature. For example, several similar geological units have been grouped to describe a particular geology. Several bore sites describing yield or chemistry information have been grouped to describe a particular hydrology. From the geology and hydrology information the hydrogeology units was delineated.

Logical Consistency: GIS editing tools were used to rectify all overshoots and undershoots in line work. Polygon data topology rules applied are must not overlap, must not have gaps and each polygon has only one label.

Completeness: Complete.
