Geoscience Australia's Integrated Geospatial Metadata Catalogues

Geoscience Australia dynamically maps metadata from two independent internal catalogues to a single standards-compliant instance using GeoNetwork. This integrated metadata covers national collections of satellite imagery, geological and topographical maps, and maritime, Aboriginal Commission, and postcode boundary datasets. The project, a collaboration with ANDS and AuScope, enables external discovery of geoscientific assets relevant to resource management, environmental safety, and marine research.

Use Cases

• Discovering satellite imagery and geological maps for resource exploitation studies.
• Identifying maritime and Aboriginal Commission boundary datasets for environmental management.
• Leveraging standardized ISO19115 metadata for cross-disciplinary research, such as marine science.
• Informing infrastructure safety decisions using integrated geoscientific and topographical data.

Strengths

• Integrates metadata from two significant internal catalogues into a single standards-compliant (ISO19115) instance.
• Covers a wide range of data types including satellite imagery, geological maps, and boundary datasets.
• Uses a dynamic mapping approach that can be applied to other data types with multiple internal databases.

Limitations

• Specific column names, row counts, file sizes, and license details are not provided in any source.
• The dataset's description is repeated verbatim across multiple entries, suggesting sparse, non-varying metadata.
• The listed last updated dates (2026-06-23, 2026-04-04) are implausible future dates, indicating potential metadata errors.
