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. Wetlands smaller than 1 ha are not delineated on the wetland data. 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.

Water Bodies formal assessment of selected areas (EPA, 2005) 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.</measDesc>

<dataLineage>
<statement>This dataset is GDA2020 compatible. The source data, and therefore the captured features are georeferenced as GDA94 (horizontal only). The horizontal accuracy of the geo-referencing and/or data collection method for this example is greater than the datum offset between GDA94 and GDA2020 (1.8 meters). The resulting dataset has been nominated as a low-accuracy GDA2020 dataset. As this data has not been directly measured in GDA2020, nor transformed to GDA2020 the resulting data is 'GDA2020 Compatible', not Compliant.
Version 6.0 – Wetland Areas (2019), is an updated version of data previously released as version 1.0 (GBR catchments), version 1.1 (Wide Bay Burnett catchments), version 1.2 (Great Barrier Reef, northern Cape York Peninsula and Queensland Murray Darling Basin), version 1.3 (Queensland) and version 2.0 to 5.0 (Queensland). Versions up to and including version 1.3 depicted extent of wetlands based on rectified 2001 Landsat ETM+ imagery, version 2.0 depicted extent of wetlands based on rectified 2005 Landsat ETM+ imagery . Version 3.0 depicted extent of wetlands in 2001, 2005 and 2009 based on rectified 2001/2005/2009 Landsat ETM+ imagery. Version 4.0 depicts the extent of wetlands in 2001, 2005, 2009 and 2013 based on rectified 2001/2005/2009/2013 Landsat ETM+ imagery. Version 5.0 depicts the extent of wetlands in 2001, 2005, 2009, 2013 and 2017 based on rectified 2001/2005/2009/2013/2017 Landsat ETM+ imagery. Version 6.0 depicts the extent of wetlands in 2001, 2005, 2009, 2013, 2017 and 2019 based on rectified 2001/2005/2009/2013/2017/2019 Landsat ETM+ imagery. This data is produced by combining the wetland regional ecosystem areas with wetland waterbody data. Where overlap occurred across wetland waterbodies and wetland regional ecosystem polygons, a decision tree is used to determine which polygon takes priority.
The extent of wetlands depicted is based on rectified 2019 Landsat ETM+ imagery (supplied by SLATS, Department of Environment and Science).
Note that some small offshore terrestrial islands may not be delineated due to the mapping extents and scale of source data and the imagery available to delineate such features.
Full details on the methodology can be found: https://wetlandinfo.des.qld.gov.au/wetlands/facts-maps/wetland-background/
Version 5.0 - Released November 2019. Queensland wetland mapping and classification for the whole state, based on 2017 extent. This includes updated mapping (fixing errors, remapping to finer scale) as well as updating the extent from 2013 to 2017, version 4.0 – Wetland Data (2013), is an updated version of data previously released as version 1.0 (GBR catchments), version 1.1 (Wide Bay Burnett catchments), version 1.2 (Great Barrier Reef, northern Cape York Peninsula and Queensland Murray Darling Basin), version 1.3 (Queensland) and version 2.0 (Queensland), versions up to and including version 1.3 depicted extent of wetlands based on rectified 2001 Landsat ETM+ imagery, version 2.0 depicted extent of wetlands based on rectified 2005 Landsat ETM+ imagery. Version 3.0 depicted extent of wetlands in 2001, 2005 and 2009 based on rectified 2001/2005/2009 Landsat ETM+ imagery. Version 4.0 depicts the extent of wetlands in 2001, 2005, 2009 and 2013 based on rectified 2001/2005/2009/2013 Landsat ETM+ imagery. This data is produced by combining (by union) the wetland regional ecosystem areas with water body data. Where overlap occurred across water bodies and regional ecosystem polygons, water body polygons take priority over regional ecosystem polygons, except for areas within mangrove and salt flat regional ecosystems. The identification of individual water bodies is not useful within these regional ecosystems, due to the limitations associated with mapping water bodies from satellite imagery in tidal areas.
The source of each polygon is recorded as a separate attribute in field ‘Source’. Wetland regional ecosystems can be identified by those records where the source is “from RE” (refer to table below for full descriptions of the source attributes).
The extent of wetlands depicted is based on rectified 2013 Landsat ETM+ imagery (supplied by SLATS, Department of Science, Information Technology, and Innovation).
The delineation of estuarine and marine wetland systems is based principally upon the OzEstuaries approach (e.g. Heap et. al., 2001) and includes a remote interpretation of vegetation and geomorphic characteristics using aerial photography and enhanced Landsat ETM+ imagery. This interpretation does not necessarily equate to the system level definitions (Environmental Protection Agency, 2005) for the classification of wetlands in Queensland and is a pragmatic, conservative approach to the delineation of these boundaries. In this data, the marine system has been defined as extending from estuarine/terrestrial system to the three nautical mile limit of Queensland waters.
Note that some small offshore terrestrial islands may not be delineated due to the mapping extents and scale of regional ecosystem data and the imagery available to delineate such features.
Water Bodies
Water bodies will have a source starting with: “MT” (multi-temporal satellite data), or ”WT” (wet scene satellite data) or “manual” (manually added waterbody) or “mod MT” (manually modified multi-temporal satellite data) or “mod WT” (manually modified wet scene satellite data) or “topo” (topographic data). Followed by a year (2001, 2005, 2009 or 2013) which represents the dataset in which the waterbody was first detected (refer to table below for full descriptions of the source attributes).
The extent of water bodies is derived from a combination of automated analysis of satellite imagery, areas depicted on topographic maps and manual interpretation of imagery.
The extent and frequency of inundation (see water regime modifier below) of water bodies were derived by Density Slicing and Normalised Difference Water Index analysis of Landsat imagery. Imagery used is rectified Landsat TM/ETM+ imagery (supplied by SLATS, Department of Science, Information Technology, and Innovation) for 1991, 1995, 1997, 1999, 2001, 2003, 2005 and one additional ‘wet scene’ selected at a time of favourable inundation conditions. The water bodies derived from image analysis were combined with water bodies extracted from Geodata (i.e., digital topographic maps). The extent of water bodies is based on the maximum extent of inundation from available Landsat imagery up to 2005. Where water bodies are comprised of data from the image analysis and the geodata, the extent is determined by the outer boundary of the combined features. The frequency of inundation (water regime modifier) for a water body is based on available Landsat imagery up to and including the 2005 imagery and is determined to be the value of the input feature that has the highest inundation frequency.
Updates to Water Bodies post 2005
Water bodies or extensions to water body extent detected post 2005 (2006-2013 imagery) were derived from Normalised Difference Water Index analysis of Landsat imagery supplied by SLATS (Department of Science, Information Technology and Innovation). Water bodies were manually assessed to separate (a) new water bodies not existing prior to 2005 (new dams); (b) previously detected water bodies that had changed significantly in extent (usually through modification); and (c) pre-existing wetlands never previously detected. Truly new water bodies (dams) were added (maximum extent of inundation) to the dataset corresponding to the period the water body was first detected (i.e., water bodies first detected in 2009 were added to the 2009 dataset). Modified; previously detected water bodies were used to update (extent and attribution) the dataset corresponding to the period the modification was first detected. Water bodies representing pre-existing wetlands detected for the first time were added to the 2001 baseline dataset. Permanent loss of wetlands/water bodies (unrelated to natural hydrological cycles of wetting and drying) was manually assessed in priority areas (areas experiencing land clearing and development). Polygons representing loss of wetlands and waterbodies were manually added to the dataset corresponding to the period the loss was detected.
Water bodies to a minimum size of 1 ha are mapped.
Wetland Regional Ecosystems
Wetland regional ecosystems, where water body polygons do not take priority (see first paragraph above under lineage), can be identified by those records where the source is “from RE” (refer to table below for full descriptions of the source attributes).
The wetland regional ecosystem data is from the 2013 extent from version 9 (1:50,000 &amp; 1:100,000 scale areas on map below) and draft mapping for the remainder of the state (1:250,000 scale below).
Regional ecosystem mapping is based on aerial photography, rectified Landsat imagery (SLATS, DSITI), geology, soils and land systems data, topographic maps, field survey, existing field site data and existing mapped data (digital and hard copy). For the wetlands mapping, coastal areas have been updated by manual incorporation of mapping of mangroves and salt flats by Queensland Department of Primary Industries and Fisheries (de Vries et al., 2002).
Regional ecosystem boundaries are drawn on aerial photographs and manually digitized. Field survey provided partial verification of boundaries. The extent of wetland regional ecosystems is derived from remnant and disturbed vegetation areas on 2013 Landsat imagery or in some cases aerial photography.
There can be multiple regional ecosystems in a polygon, which can be wetland and non-wetland types. A regional ecosystem polygon is included as a wetland if the proportion of wetland regional ecosystems in the polygon is greater than 80%. A regional ecosystem polygon is included and flagged as containing a wetland if the proportion of palustrine and lacustrine wetland regional ecosystems in the polygon is between 1 and 80%.
Regional ecosystem mapping used is complied to 1:50,000, 1:100,000 and 1:250,000 scale as shown in the figure below.
