Purpose

The IWC is used principally to assess wetland condition. This data set communicates the results of 389 IWC assessments conducted between January 2009 and April 2011 as part of the then Department of Environment and Primary Industries (DEPI) 2010 initiative to provide a snapshot of the condition of Victoria's wetlands.

Quality

Conceptual Consistency

Each assessment includes the assessment date, wetland ID and resulting IWC scores. The scores are linked to the wetland boundary mapping (refer WETLANDS_CURRENT dataset) via using the ID number which is a concatenation of the Victorian map sheet in which the wetland is located and the unique Wetland number. This data set only includes the wetland boundaries for wetlands in which an assessment was made. 

Missing Data

All wetlands with an area of 1 hectare or more should be present. Monitored segments of Victorian waterways 

Attribute Quality

IWC scores are derived from field assessments and are considered accurate for the date and time of each assessment. 

Positional Accuracy

+/- 50m 

Lineage

Statement

Dataset Source: IWC Scores were obtained from the Index of Condition website (now offline). Wetland boundaries obtained from DELWP's WETLAND_CURRENT dataset and aligned using the ID number which is a concatenation of the Victorian map sheet in which the wetland is located and the individual Wetland number. Dataset Originality: Primary & Derived
