Making knowledge of Geoscience Australia's data and information assets accessible to the e

Geoscience Australia's metadata catalog provides access to national collections of satellite images, geological and topographical maps, and boundary datasets. The metadata was mapped to the ISO19115 schema and is exposed via a GeoNetwork instance, enabling dynamic mapping from two internal catalogues. The data supports decisions on resource exploitation, environmental management, and infrastructure safety.

Use Cases

• Analyzing land cover and environmental changes based on national satellite image collections.
• Conducting geological surveys and resource exploration based on geological map collections.
• Planning maritime and administrative projects based on boundary datasets for maritime and postcode areas.
• Integrating diverse geoscientific data for thematic mapping based on the standardized ISO19115 metadata schema.

Strengths

• Metadata is standardized to the ISO19115 schema, facilitating interoperability.
• Aggregates data from two significant internal catalogues covering satellite, geological, and boundary datasets.
• The approach enables dynamic mapping from multiple internal databases without requiring a single consolidated internal catalogue first.

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 is unknown, which may limit suitability assessment.
