Abstract
The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.
This database is an update (v2) of the initial asset database for the Gwydir subregion (titled "Asset database for the Gwydir subregion on 8 May 2015", ID 429a2721-6fc1-4f3b-96d1-3eaeaa98a993).
This dataset contains a combination of spatial and non-spatial (attribute) components of the Gwydir subregion Asset List - an mdb file (readable as an MS Access database or as an ESRI personal geodatabase) holds the non-spatial tabular attribute data, and an ESRI file geodatabase contains the spatial data layers, which are attributed only with unique identifiers ("AID" for assets, and "ElementID" for elements). The dataset also contains a draft "Water-dependent asset register and asset list" spreadsheet (BA-NIC-GWY-130-WaterDependentAssetRegister-AssetList-V20150824.xlsx).
The tabular attribute data can be joined in a GIS to the "Assetlist" table in the mdb database using the "AID" field to view asset attributes (BA attribution). To view the more detailed attribution at the element-level, the intermediate table "Element_to_asset" can be joined to the assets spatial datasets using AID, and then joining the individual attribute tables from the Access database using the common "ElementID" fields. Alternatively, the spatial feature layers representing elements can be linked directly to the individual attribute tables in the Access database using "ElementID", but this arrangement will not provide the asset-level groupings.

Dataset History
VersionID Date Notes
1.0 8/05/2015 Initial database
2.0 24/08/2015 v2 - additions as follows:
(1) At the request of NSW OEH, data identifying species and ecological communities listed under NSW legislation has been included in two additional attribute tables "NSW_TS" and "NSW_TEC" (a total of 110 elements and assets, AIDs 70150-70259). However, given the extremely course catchment-scale resolution of the data as compared to the relatively fine-scale of the PAE, it is essentially a non-spatial list of species and communities which may or may not occur within the PAE. As the data was unable to be meaningfully used as a spatial dataset it was subsequently "turned off" at decision M0 (not fit for purpose), with the decision reflected in the "Assetlist"and "AssetDecisions" tables. Although they are included in the asset database, these new assets are not included in the asset count for GWY.
(2) The database has been updated to include M2 (water dependency) test results from the GWY project team, and a draft "Water-dependent asset register and asset list" spreadsheet (BA-NIC-GWY-130-WaterDependentAssetRegister-AssetList-V20150824.xlsx) has been created and is included in this dataset.
(3) Four queries have been added to the non-spatial database (mdb) (Find_All_Used_Assets, Find_All_WD_Assets, Find_Amount_Asset_in_Class and Find_Amount_Elements_in_Class) to assist project teams to identify and calculate figures to be published.
Further information is contained in the associate document "GWY_asset_database_doc_20150824.doc".
