Quality

Conceptual Consistency

Attributes are fully populated allowing the Victorian Wetland Classification to be applied to all wetlands. 

Missing Data

The dataset is considered to be complete. All wetlands with an area of 1 hectare or more should be present. 

Attribute Quality

The classification scheme is applied using many different sources of data, or with logical default values when no source is available. A confidence measure is provided for each attribute used in the classification. 

Positional Accuracy

Boundary accuracy for new mapping and repositioning 25m or better. 

Lineage

Statement

WETLAND_CURRENT was created in 2013 from WETLAND_1994 (the state's first wetland geospatial inventory) and several local and regional wetland datasets. A number of updates have occurred to the dataset during 2014, 2017 and 2021. The 2014 update incorporated new regional mapping, some supplementary mapping and repositioning of planimetrically inaccurate wetlands using aerial photograph interpretation (photos from 2007 to 2011) supplemented with existing geospatial datasets. The 2017 update improved the accuracy of the layer by updating wetland mapping and attributes in the Melbourne area and for alpine bogs and fens in East and West Gippsland catchment regions. It also involved correcting inaccurate classification attributes and correcting wetland polygons for individual wetlands based on new data and feedback from wetland inventory users. The 2021 update incorporates new mapping and refinements to existing wetland polygons for several regional wetland datasets. These include Tootgarook Swamp, Alpine Bogs, Mitchell River Floodplain Wetlands, Melbourne Water Billabongs and Mallee CMA Wetlands. The 2025 revision incorporated additional wetland boundaries from other state sources including VicMAP Hydro, regional mapping by Catchment Management Authorities, Melbourne Water, saltmarsh and estuarine vegetation mapping and state mapping of dams and storages. Attributes required by the Victorian Wetland Classification Framework (system type, salinity regime, water regime, water source, dominant vegetation) were fully populated replacing many "unknown" or missing values with nominal values to permit all wetlands to be classified to their wetland type. Confidence scores were added reflecting the strength of evidence in the attributes. The wetland origin attribute was incorporated into the system type creating a greater distinction between constructed features (e.g. dams, aquaculture tanks, mine pits, treatment plants) and naturally occurring depressional lakes and wetlands.
