Title: Coastal Wetlands (State Environmental Planning Policy No. 14) - SEPP 14
Custodian: NSW Department of Planning
Jurisdiction: New South Wales
Boundary data on more than 1500 coastal wetlands of State significance and covered by State Environmental Planning Policy No. 14 (SEPP 14) as defined in The Coastal Wetlands Survey Report, prepared by Dr P Adam, Mr N Urwin, Mr P Weiner and Mr I Sim for the Coastal Council of New South Wales, 1985. SEPP 14 places planning and development controls under the Environmental Planning and Assessment Act, 1979 over the wetlands, which are illustrated on 82 hard copy printed maps that have been gazetted. These hard copy maps are the definitive source of the wetland boundaries although digital representation is also available. Coverage extends along the NSW coastline (and up to 30 kms inland) from the Queensland border to the Hawkesbury River and from Wollongong to the Victorian Border.
Note: SEPP 14 excludes the Sydney metropolitan region, that is, the Hawkesbury River to Wollongong.

Lineage:
For the original wetlands survey, the NSW coastline, coastal plain areas and major estuarine river system were covered by an aerial photographic survey, carried out in 1981. The survey followed specifications set up by the then Department of Urban Affairs and Planning and are described in the Coastal Wetlands Survey Report of 1985. Seven wetland types were included: mangroves, saltmarshes, melaleuca forests, casuarina forests, sedgelands, brackish and freshwater swamps and wet meadows. The wetland boundaries were identified from the aerial photos on a botanical basis, using their vegetation features. They were delineated using stereoscopic interpretation (at up to 7 times magnification) of 1:25000 aerial photos. As the photographic scale closely approximated the 1:25000 scale of the LIC topographic map series, the transfer from photograph to map was carried out at close to one time magnification with minimum distortion. For a number of key areas, the photographic interpretations were checked and verified by inspections on the ground. The coastal wetland maps compilation was finished in 1984. A major aerial photo re-survey of the coastal area was carried out by LIC in 1986, and subsequently the wetland boundaries were then updated. They have subsequently been amended from time to time as required through a gazetted amendment to SEPP 14. The compiled maps were hand digitised using Genamap GIS software. The digitising accuracy is estimated to be 0.5 mtr on the 1:25000 maps. The wetlands polygons are labelled with numbers allocated in a sequential order from north to south between the Queensland border and the Hawkesbury River, and south to north from the Victorian border to Wollongong.
Positional accuracy:
Coastal wetlands are under continuous temporal changes. This is why they are amended as required. The positional accuracy of the wetland boundaries is considered to be around 25 mts on 1:25000 maps.
Wetlands on the printed 1:25000 maps are defined by the outside edge of the thick black line which delineates the wetland area. The outer edge was followed in the digital version.
Attribute accuracy:
The attribute of this data set is the vegetation/land cover type. This attribute is not mapped but is kept in a manual file system ordered by the coastal wetland number. The wetlands are delineated on 1:25000 maps without additional details about their composition (vegetation features). No attempt has been made to subdivide the wetlands into different types of botanical communities. Consequently, the wetlands delineation was made based on their vegetation features as botanical indicators, and not the geomorphic ones. The interpretation criteria developed for botanical indicators establishes the seven components which could be recognised from the aerial photgraphs and which characterises the wetlands, as well as seven vegetation land cover types which are not included in the definition of wetland. The criteria is detailed in the Coastal Wetlands Survey Report of 1985.
Logical consistency:
The tests for logical consistency involve a visual check of maps, especially in the preparatory stages of map production and a topological check of the digitised GIS data.
Consistency checks reveal that the boundaries of some wetlands that cross the common border of adjacent maps have not been edge matched. Consequently, there may be offsets between the two parts of a wetland, or in some cases one part of a wetland may not appear. Also the wetland identifier is not shown for a small number of wetlands (2 percent).
Completeness:
Most wetlands were delineated if they could be unambiguously identified on the photographs. A limit of approximately 4 hectares was chosen as a minimum size for the mapping of Sedgeland, Freshwater Swamp and Wet Meadow components on a flood plain. For the other four wetland types, the minimum size delineated was limited only by the optical factors of interpretation.
