Queensland Coastal Wetlands (Mangroves, saltpans, samphire), 1987 - 1997 (DEEDI)

Brief description

1:100,000 coastal wetland vegetation mapping for the Queensland coastline including mangrove communities, saltpans and saline grasslands. Mangrove areas are classified based on the dominant genus (Ageiceras, Avicennia, Ceriops, Bruguiera, Rhizophora). This dataset was derived from automatic classification of 25m resolution Landsat TM images, colour aerial photography and ground truthing. The resulting data has a positional accuracy of 100 meters and a classification accuracy of approximately 80%. Additional metadata and access to the data is available on the Queensland Coastal Wetlands Resources Mapping data, eResearch Archive. http://era.deedi.qld.gov.au/1774/ Format: Data currency is noted for each shapefile below: * Gulfwtlds.shp (36 MB, polygons, Datum: GDA94, 1995) - NT border to Flinders River - 1995 - SE Gulf of Carpentaria - 1987, 1988, 1991, 1992 * Northernwtlds.shp (11 MB, polygons, Datum: GDA94, 1987-1992) - Cape York Peninsula - 1986-88, 1991 * Centralwtlds.shp (26 MB, polygons, Datum: GDA94, 1986-) - Cape Trib to Bowling Green Bay - 1997-99 - The Burdekin Region - 1991 - The Bowen Region - 1994-95 - The Whitsunday Region - 1997 - Repulse Bay - 1989 - Central Qld - 1995, 1997 - The Curtis Coast Region - 1997 * Southernwtlds.shp (4 MB, polygons, Datum: GDA94) - Round Hill Head to Tin Can Inlet - 1997 - Moreton Region - 1995 An aggregate of all the four shapefiles above was prepared for the eAtlas, creating an aggregate for Queensland. In addition to this a shapefile was created describing the age of the various regions. These derived shapefiles are available for download on this page. All four regional shapefiles, and the Queensland aggregate contain the same attributes * AREA_M2: Area of the polygon in m² * CLASS: - Closed Aegiceras - Closed Avicennia - Closed Avicennia/Aegiceras - Closed Avicennia/Ceriops - Closed Bruguiera - Closed Ceriops - Closed Mixed - Closed Rhizophora - Closed Rhizophora/Aegiceras - Closed Rhizophora/Avicennia - Open Avicennia - Open Avicennia/Ceriops - Open Bruguiera - Open Ceriops - Saline Grassland - Saltpan - Samphire-dominated Saltpan - Sparse Seagrass - Water and Terrestrial Data Location: This dataset is filed in the eAtlas enduring data repository at: data\other\QLD_DEEDI_Coastal-wetlands_1987-1997
