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

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.

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
