GBR - Features: Reef boundaries, Queensland Coastline, Islands, Cays and Rocks (GBRMPA)
This dataset contains two shapefiles describing the boundaries of the coral reefs within the Great Barrier Reef.
The first shapefile (GBR_FEATURES.shp) contains coastal features within and adjacent to the Great Barrier Reef World Heritage area. This is the dataset used by Google Maps for its reef outlines. The features in this dataset have a resolution of approximately 1:50,000. The following features are included:
- Queensland mainland coastline
- Major and other coral reef structures (as defined by the reef shoal edge) within the Great Barrier Reef World Heritage Area
- Islands and rocks (exposed and submerged)
- Major coral cay features. These correspond to the outer boundaries of the reefs based on a survey done by the GBRMPA using Landsat imagery.
The second shapefile (GBRMPA_reefs-dry_reefs) contains major tidal, drying or emergent reef areas within the Great Barrier Reef World Heritage Area.
To obtain this dataset go to the GBRMPA spatial information website, download the appropriate data usage agreement and send it through to email@example.com. The GBRMPA name for this dataset is "Great Barrier Reef features".
KML files for this dataset (and others) can be obtained from the GBRMPA Google Maps page.
