The NGIS aquifer salinity dataset was loaded into the updated Geofabric Aquifer Salinity data model. HydroIDs were assigned to each aquifer feature. Selected attributes were also updated e.g. dates and agency name changes. Detailed processing metadata for the NGIS aquifer salinity dataset can be found in the NGIS Data Product Specification: http://www.bom.gov.au/water/groundwater/ngis/documents/NgisProductSpec.pdf AHGFAquiferSalinity Data sources - Basin in a Box (MDBA) - Southern Victoria Groundwater mapping (SRW) - Geodata v3 framework data set (GA) - Groundwater salinity, Superficial and Confined Aquifers (DWER) - National Groundwater Information System (NGIS) aquifer boundary dataset (Bureau of Meteorology, 2020) - National Aquifer Framework (NAF), version 1.1, (Bureau of Meteorology, 2016) Processing steps Geofabric Version 2 Jurisdictional datasets were initially collated, pre-processed and standardised into a national dataset: Grid to polygon conversion for Southern Victoria. Data sets were combined into a single ArcInfo coverage and adjusted to align with the national coastline and then converted to a single file geodatabase feature class. Overlapping salinity polygons were clipped to their respective aquifer boundary, typically slivers resulting from digitising errors. Where underlap slivers existed, the polygons were extended to match the aquifer boundary. Geofabric Version 3 Version 2 datasets were aligned to the NAF and new aquifer boundary dataset: The data model for Geofabric Aquifer Salinity dataset was updated to include NAF and aquifer type attributes and to remove Interim Aquifer Framework attributes.
