eReefs Basemap: GIS Layers for the Great Barrier Reef and Coral Sea

A collection of GIS layers for creating printed maps of the Great Barrier Reef and Coral Sea. The collection includes datasets for countries, 21 cities along the Queensland coast, drainage basins, rivers, and reef boundaries, derived from sources like Natural Earth Data and Geoscience Australia. The data is simplified for low-detail map rendering and is hosted by the Australian Ocean Data Network.

Use Cases

• Creating A4 printed maps of the Great Barrier Reef based on the provided GIS layers.
• Visualizing river basins along the eastern Queensland coastline for environmental planning.
• Rendering simplified reef boundaries for regional overview maps in the Coral Sea and Torres Strait.
• Clipping other eReefs data to specific regions like the GBR using the provided clip polygons.

Strengths

• Includes an integrated 'Land and Basins' layer designed to optimize map rendering time.
• Contains 21 specific cities along the Queensland coastline for reference.
• Reef boundaries are derived from multiple authoritative sources including GBRMPA and AIMS datasets.

Limitations

• Data has been cropped and simplified for low-detail printed maps and is not suitable for high-resolution analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
