Polygon extents represent bathymetry compilation products delivered by Geoscience Australia as of June 2019. The compilations were generated from numerous data sources including survey data, lidar, and interpolation. Each polygon's attributes contain information regarding data sources, product details, and access methods.
Use Cases
- Map seabed coverage for marine planning based on the described polygon extents.
- Identify data sources for bathymetric surveys based on the attribute information.
- Assess data availability for specific ocean regions based on the spatial extents.
Strengths
- Compilation products integrate data from numerous sources including survey data and lidar.
- Attributes contain specific information on data sources, product details, and access methods.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
