The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. You can find a link to the parent datasets 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 map each groundwater works with the volumetric entitlement without double counting the volume and to aggregate/ disaggregate the data depending on the final use.
This has not been clipped to the NIC PAE, therefore the number of economic assets/ relevant licences will drastically reduce once this occurs.
The Northern_Inland_Catchment groundwater licences includes an extract of all licences that fell within the data management acquisition area as provided by BA to NSW Office of Water.
Aim: To get a one to one ratio of licences numbers to bore IDs.
Important notes about data:
Data has not been clipped to the PAE.
No decision have been made in regards to what purpose of groundwater should be protected. Therefore the purpose currently includes groundwater bores that have been drilled for non-extractive purposes including experimental research, test, monitoring bore, teaching, mineral explore and groundwater explore
No volume has been included for domestic & stock as it is a basic right. Therefore an arbitrary volume could be applied to account for D&S use.
Original spread sheets (GUID= 808fd05a-f451-4170-a1d3-8439105c0273) have mulitple licence instances if there are more than one WA/CA number. This means that there are mpre than one works or permit to the licence. The aim is to only have one licence instance.
The individual licence numbers were combined into one column
Using the new column of licence numbers, several vlookups were created to bring in other data. Where the columns are identical in the original spreadsheets, they are combined. The only ones that dont are the Share/Entitlement/allocation, these mean different things.
A hydro ID column was created, this is a code that links this NSW to the NGIS, which is basically a ".1.1" at the end of the bore code.
All 'cancelled' licences were removed
A count of the number of works per licence and number of bores were included in the spreadsheet.
Where the ShareComponent = NA, the Entitlement = 0, Allocation = 0 and there was more than one instance of the same bore, this means that the original licence assigned to the bore has been replaced by a new licence with a share component. Where these criteria were met, the instances were removed
a volume per works ensures that the volume of the licence is not repeated for each works, but is divided by the number of works
