Geoscience Australia's Geoscientific Metadata from Multiple Internal Catalogues

Geoscience Australia's internal catalogues hold metadata for national collections of satellite images, geological maps, and boundary datasets. Staff mapped this metadata to the ISO19115 standard to enable external access via a GeoNetwork instance. This approach allows dynamic mapping from two independent catalogues without requiring a single consolidated internal source.

Use Cases

• Discover satellite imagery and datasets for environmental monitoring based on the described national collections.
• Access geological and topographical maps for resource exploration and land management.
• Identify maritime or Aboriginal Commission boundary datasets for spatial analysis and planning.
• Leverage standardized ISO19115 metadata for integrating geoscientific data into research workflows.

Strengths

• Metadata is mapped to the international ISO19115 standard, facilitating interoperability.
• Data originates from Geoscience Australia, a national geoscientific authority.
• The approach dynamically maps from two independent internal catalogues, avoiding a manual consolidation step.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file sizes are unknown, which may limit suitability assessment.
