Description

Abstract:

This spatial dataset, surveyed at a scale of 1:250000, provides polygon information on the Groundwater, Mereenie Aquifer groundwater salinity and Alluvial Aquifer water quality and watertable elevation map unit of the Alice Springs water control district, Northern Territory. The purpose of this survey was to map, describe and evaluate the water resources information for planning and management.

Data Quality

Lineage:Groundwater, Mereenie Aquifer groundwater salinity and Alluvial Aquifer water quality and watertable elevation 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 polygon collected via geographic Information system (ArcGIS). Core water resources attributes attached to map units boundary with additional attributes unique to individual surveys. The ESRI Geodatabase, MapInfo Table and Google Earth KML derived using FME Workbench. The published map is derived from the ESRI Shape using Microstation Bentley MicroStation Design (V8) software.

The core attributes information associated with the groundwater, surface water and water development dataset was derived from the original map's legend and annotations. File name Alice_Springs_groundwater_250K.dgn. Additional attributes unique to individual surveys were also included.

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 topology rules applied are must not overlap, must not have gaps and each polygon has only one label. .

Completeness:Complete.
