Gloucester NGIS bores

Abstract

This dataset was derived from the NGIS Geodatabase. 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 NGIS dataset has been clipped to the Gloucester subregion.

The NGIS geodatabase was developed by lead water agencies from all States and Territories based on the NGIS data model, which was developed and maintained by the Bureau. Refer to the NGIS Data Dictionary and Schema Diagram (included) for further information on the NGIS data model.

The format for NGIS is an ESRI file geodatabase. ESRI ArcGIS Version 10 (or beyond) is needed to use NGIS.

The National Groundwater Information System (NGIS) is a geodatabase for storing nationally consistent groundwater data based on ESRI's ArcHydro for Groundwater data model. It focuses on bore and bore log (lithology, bore construction and hydrostratigraphy) data. It also includes georasters and geovolumes for selected areas.

The Bureau of Meteorology maintains the NGIS data model that standardises and spatially-enables groundwater data. The lead water agencies in each State/Territory (plus Water Corporation in Western Australia) export data from their corporate groundwater databases into State/Territory NGIS geodatabases. The Bureau of Meteorology maintains the NGIS data model and collates State/Territory geodatabases into the national geodatabase.

The data product extent is Geographic Australia (as defined by Acts Interpretation Act 1901). The product will be updated in December of each year following the receipt of updated State/Territory geodatabases at the end of September through the Water Regulations (Commonwealth legislation that requires agencies to deliver water data to the Bureau under the Water Act).

The NGIS contains the following datasets:

Bore - Point feature class that represents the location of a bore and associated attributes. Multiple independently screened bore pipes are regarded as a separate bore features.

Bore log - Hydrostratigraphy log. Table with strata classified into hydrogeological units along a borehole

Lithology log - Table with driller's or geologist's description of rock or sediment types along a borehole

Construction log - Table with bore construction information along a borehole (e.g. casing and screen)

Bore line - 3D line feature class that represents the hydrogeologic units along a borehole

Construction line - 3D line feature class that represents the construction information (e.g. casing and screen) along a borehole

Hydrogeologic unit - Table summarising hydrogeologic units and hydrogeologic complexes and their attributes. Includes both state/territory and National Aquifer Framework (NAF) terminology.

Dataset History

Bore locations in the _National_Groundwater_Information_System_v1.1_Sept2013 database that were spatially located within the Gloucester subregion boundary were extracted and filed in the BA_SYD/GLO project area.
