Coastal Bathymetric Composite Surfaces For 29 Australian Regions

29 composite surface surveys from Australian coastal regions, created from multibeam, laser, and LIDAR data by the Department of Transport. This polygon feature class provides extents and URLs to 32-bit TIFF files stored on Amazon S3 for public download, with images processed at a 5-meter resolution.

Use Cases

• Analyze coastal bathymetry changes by comparing composite surface extents and URLs across the 29 listed regions like Albany and Broome.
• Integrate polygon extents with other marine spatial data for regional coastal zone management and habitat mapping.
• Download 32-bit TIFF files via the provided URLs for high-resolution seafloor modeling and elevation analysis.

Strengths

• Covers 29 distinct coastal regions across Australia, from Yalgorup to Warnbro.
• Provides direct URLs to the underlying 32-bit TIFF raster files for download.
• Managed by the authoritative Coastal Information Branch of the Department of Transport.

Limitations

• No row or column count is provided, limiting understanding of dataset scale.
• Data is delivered as a map service, requiring GIS software or specific API knowledge for access.
• The description lacks technical details on data density, accuracy, or processing methodology.
