This data set holds the publicly-available version of the database of water-dependent assets that was compiled for the bioregional assessment (BA) of the Namoi subregion as part of the Bioregional Assessment Technical Programme. Though all life is dependent on water, for the purposes of a bioregional assessment, a water-dependent asset is an asset potentially impacted by changes in the groundwater and/or surface water regime due to coal resource development. The water must be other than local rainfall. Examples include wetlands, rivers, bores and groundwater dependent ecosystems.
The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets including Natural Resource Management regions, and Australian and state and territory government databases. 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. A single asset is represented spatially in the asset database by single or multiple spatial features (point, line or polygon). Individual points, lines or polygons are termed elements.
This dataset contains the unrestricted publicly-available components of spatial and non-spatial (attribute) data of the (restricted) Asset database for the Namoi subregion on 18 February 2016 (22061f2c-e86d-4ca8-9860-c349c2513fd8). The database is provided primarily as an ESRI File geodatabase (.gdb), which is able to be opened in readily available open source software such as QGIS. Other formats include the Microsoft Access database (.mdb in ESRI Personal Geodatabase format), industry-standard ESRI Shapefiles and tab-delimited text files of all the attribute tables.
The restricted version of the Namoi Asset database has a total count of 44 722 Elements and 2174 Assets. In the public version of the Asset Namoi database 13750 spatial Element features (~31%) have been removed from the Element List and Element Layer(s) and 99 spatial Assets (~5%) have been removed from the spatial Asset Layer(s)
The elements/assets removed from the restricted Asset Database are from the following data sources:
Environmental Asset Database - Commonwealth Environmental Water Office - RESTRICTED (Metadata only) (29fd1654-8aa1-4cb3-b65e-0b37698ac9a6)
Key Environmental Assets - KEA - of the Murray Darling Basin RESTRICTED (Metadata only)( 9948195e-3d3b-49dc-96d2-ea7765297308)
Australia, Register of the National Estate (RNE) - Spatial Database (RNESDB) (Internal 878f6780-be97-469b-8517-54bd12a407d0)
4)Species Profile and Threats Database (SPRAT) - RESTRICTED - Metadata only) (7276dd93-cc8c-4c01-8df0-cef743c72112)
These important assets are included in the bioregional assessment, but are unable to be publicly distributed by the Bioregional Assessment Programme due to restrictions in their licensing conditions. Please note that many of these data sets are available directly from their custodian. For more precise details please see the associated explanatory Data Dictionary document enclosed with this dataset.
The Asset List Database was developed to spatially identify water dependent assets found within the Namoi subregion.
The public version of the asset database retains all of the unrestricted components of the Asset database for the Namoi subregion on 18 February 2016 - any material that is unable to be published or redistributed to a third party by the BA Programme has been removed from the database. The data presented corresponds to the assets published Namoi subregion product 1.3: Description of the water-dependent asset register and asset list for the Namoi subregion on 18 February 2016, and the associated Water-dependent asset register and asset list for the Namoi subregion on 18 February 2016.
Individual spatial features or elements are initially included in database if they are partly or wholly within the subregion's preliminary assessment extent (Materiality Test 1, M1). In accordance to BA submethodology M02: Compiling water-dependent assets, individual spatial elements are then grouped into assets which are evaluated by project teams to determine whether they meet materiality test 2 (M2), which are assets that are considered to be water dependent.
Following delivery of the first pass asset list, project teams make a determination as to whether an asset (comprised of one or more elements) is water dependent, as assessed against the materiality tests detailed in the BA Methodology. These decisions are provided to ERIN by the assessment team and incorporated into the AssetList table in the Asset database.
Development of the Asset Register from the Asset database:
Decisions for M0 (fit for BA purpose), M1 (PAE) and M2 (water dependent) determine which assets are included in the "asset list" and "water-dependent asset register" which are published as Product 1.3.
The rule sets are applied as follows:
M0 M1 M2 Result
No n/a n/a Asset is not included in the asset list or the water-dependent asset register
(≠ No) No n/a Asset is not included in the asset list or the water-dependent asset register
(≠ No) Yes No Asset included in published asset list but not in water dependent asset register
(≠ No) Yes Yes Asset included in both asset list and water-dependent asset register
Assessment teams are then able to use the database to assign receptors and impact variables to water-dependent assets and the development of a receptor register as detailed in BA submethodology M03: Assigning receptors to water-dependent assets and the receptor register is then incorporated into the asset database.
At this stage of its development, the Asset database for the Namoi subregion on 18 February 2016, which this document describes, does not contain receptor information.
