This dataset provides mapping of water bodies and wetland regional ecosystems as at 2013 extent at 1:100,000 scale across Queensland. Brisbane City and areas covered by a Property Map of Assessable Vegetation (PMAV) may be mapped at 1:25,000 scale.
Resource purpose/summary
To report and monitor wetland extent and type and change in extent and type.
Wetlands linework reproduced at a scale greater than 1:100,000, except in designated areas, should be used as a guide only.

Regional Ecosystems
Formal and informal assessments show regional ecosystem attributes to be accurate > 80% of the time.
Water Bodies
Formal assessment of selected areas (DES, 2019) has shown that the delineation of wetlands by the water body mapping to have an overall accuracy of between 93-98%. The producer’s accuracy of non-wetlands (i.e. how accurately non-wetland areas are mapped and the user’s accuracy for wetlands (i.e. how accurate areas mapped as wetland are wetland) is also consistently high ranging from 77-99%.
The water body mapping does miss substantial areas of wetland, as the producer’s accuracy for wetlands is relatively low ranging from 14-54%. However, as the wetland regional ecosystem data maps areas of wetlands that are not well mapped by the water body data, many of these areas are not missing from the wetlands data.
Report
Data quality report, measure description
The positional accuracy of wetland data mapped at a scale of 1:100 000 is +/-75 metres. The minimum polygon size depicted is 5 ha or 75 metres wide for linear features, except for areas along the east coast which are mapped at the 1:50 000 scale with a positional accuracy of +/-50 metres, with a minimum polygon size of 1 ha or 35 metres wide for linear features.
NB: Consideration of the effects of mapped scale is necessary when interpreting data at a larger scale, (eg: 1:25,000). For property assessment, digital linework should be used as a guide only.
