Dataset: Asset database for the Gloucester subregion on 12 February 2016 Public v02

Description

Abstract

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.

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 Gloucester 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.

Under the Bioregional Assessment Technical Programme (BATP), a spatial assets database was developed for each bioregion and / or subregion. 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.

The spatial elements that represent assets were identified by regional natural resource management organisations and collated by ERIN into state databases using the Water Asset Information Tool (WAIT). These data were supplemented with additional information from appropriate Australian and state and territory government databases. The materiality of each asset was tried against a series of tests and the consequent decisions were also included in the asset database. Each asset database is therefore a rich collation of information about the assets and how they have been assessed.

All assets and elements also have associated attribute data; these are stored in attribute tables, including associated lookup tables (LUTs). Some data in the asset database are not associated with spatial data; typically these data relate to the database itself e.g. versioning information

This dataset contains the unrestricted publicly-available components of spatial and non-spatial (attribute) data of the (restricted) Asset database for the Gloucester subregion on 12 February 2016 (72a47bec-1393-49d6-b379-0e48551d26a9). 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 Gloucester Asset database has a total count of 4029 Elements ( including 11 aspatial elements) and 229 Assets (including 11 aspatial Assets ) . In the public version of the Asset Gloucester database 789 (19%)> Elements (spatial features) have been removed from the Element List and spatial Element Layer(s) and 42 Assets (19%) have been removed from the spatial Asset Layer(s)

The elements/assets removed from the restricted Asset Database are from the following data sources:

  1. Species Profile and Threats Database (SPRAT) Metadata only) (7276dd93-cc8c-4c01-8df0-cef743c72112)

  2. Australia, Register of the National Estate (RNE) (Internal 878f6780-be97-469b-8517-54bd12a407d0)

  3. Communities of National Environmental Significance Database - RESTRICTED - Metadata only (c01c4693-0a51-4dbc-bbbd-7a07952aa5f6)

  4. Fish Biodiversity Hotspot sampling data

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.

Purpose

Used for Gloucester subregion for bioregional assessments

Dataset History

The public version of the asset database retains all of the unrestricted components of the Asset database for the Gloucester subregion on 12 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 Gloucester subregion on 12 February 2016 Public, which this document describes, does contain receptor information, but it was removed from this public version

The source metadata was updated to meet the purpose of the Bioregional Assessment Programme
