This dataset was derived from groundwater data provided by the NSW Office of Water. You can find a link to the source dataset in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.
The aim of this dataset was to be able to estimate the volumetric entitlement for each groundwater works/bores and its location relative to the water source area in the Gloucester subregion. An estimation of volumetric extraction is made based on the yield values reported in the original data sets provided by the NSW Office of Water. This has been clipped to the Gloucester subregion.
A spatial dataset (point shapefile GLO_Bore_extractions.shp) has been derived from this data for report map purposes. Also the point TDS values have been interpolated into surfaces (separate Aquifer and Fractured Rock).
These spatial data derivations are also included in the dataset.
Bore locations in the National_Groundwater_Information_System_v1.1_Sept2013 database that were spatially located withing the Gloucester subregion boundary were extracted and filed.
Groundwater works with the volumetric entitlement in the NSW Office of Water_GW licence extract linked to spatial locations_GLO_v5_UID_elements_27032014 database that were spatially located withing the Gloucester subregion boundary were extracted and filed.
Based on the Yield values reported in the NSW Office of Water_GW licence extract linked to spatial locations_GLO_v5_UID_elements_27032014 databse, groundwater extraction volumes were estimated and filed.
