Data Quality

Lineage:This data was created using a combination of datasets to determine groundwater potential in the Katherine Mapping the Future study area.

Datasets include:
Bores - Water Quality, metadata: https://www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=198C4DFC3CCBC9FBE0632144CD9B5870
Bores - metadata: https://www.ntlis.nt.gov.au/metadata/export_data?metadata_id=2DBCB7711FC106B6E040CD9B0F274EFE&type=html
Aquifers - metadata: https://www.ntlis.nt.gov.au/metadata/export_data?metadata_id=535D1EECEB0F528AE040CD9B21446C20&type=html

The process for dataset creation is provided in the accompanying technical report Groundwater Resources of the Katherine Area, https://hdl.handle.net/10070/950983

Positional Accuracy:Polygons/ boundaries delineated using Northern Territory Groundwater - Aquifers dataset at the scale of 1:2,000,000

Attribute Accuracy:Attribute values, as described in the Data Dictionary below, have been added to each polygon.

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

DESC The Desc field provides a detailed description of the GW_Potential field.

GW_Potential To conform with other Mapping the Future studies the groundwater resource potential for the Katherine area is presented using resource development risk classes. Areas of high resource potential have a low risk for users accessing groundwater while areas of low groundwater resource potential are associated with a high risk for development.
The resource potential is based on the underlying characteristics of the aquifers (i.e. yield, quality, depth) and is distinct from water availability which considers existing groundwater allocations and use
The resource potential is based on a combination of the following attributes:
- Typical bore yield range for the aquifers.
- Water quality (Electrical Conductivity). Aquifers with fresher groundwater have greater resource potential as the water is suitable for a broader range of uses.
- Scale of the aquifer system - Regional aquifers have greater groundwater storage capacity relative to local scale aquifers. Drilling success rates are also generally higher when targeting regional scale aquifers.
- Groundwater accessibility - Shallow aquifers are considered to have greater resource potential because accessing groundwater in these systems is easier and less expensive relative to targeting deeper, confined aquifers.
