Description
This spatial dataset, surveyed at a scale of 1:250,000 provides polygon information on the Groundwater, Surface Water and groundwater salinity units boundaries of Arnhem Land, Northern Territory. The aim of the study is to provide an information resource which will help land owners and land managers incorporate water resource related aspects in their planning processes. This report provides an explanation of the groundwater and surface water resources in East Arnhem Land.

Data Quality
Lineage:The original Groundwater, Surface Water and groundwater salinity map unit boundaries were derived from geology maps, topographic maps, aerial photographs and stereoscope interpretation and satellite imagery interpretation. The hydrology information was interpreted from standing water level measurements, flows from springs, chemical analysis of groundwater samples and surveys of outcrops of recharge beds.
The map unit boundaries polygons were digitised by rectifying original hard copy base map use in the raster and hydrology interpretations using Bentley MicroStation Design (V7) software. FME Workbench script was then used to convert the unit boundary polygons from MicroStation Design to ESRI Shape with only the Level Names as an attribute. The core water attributes are then attached to this ESRI Shape, which was then use to convert to ESRI Geodatabase, MapInfo Table and Google Earth KML.
The core attributes information associated with the groundwater and surface water dataset was derived from the original map's legend and annotations. File name East_Arnhem_500k_Wrs.dgn.
Positional Accuracy:Positional accuracy of 250 metres from known points.
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 topology rules applied are must not overlap, must not have gaps and each polygon has only one label.
Completeness:Complete.
