Geoscience Australia's National Collections of Satellite, Geological, and Boundary Data

Geoscience Australia's internal catalogues contain metadata for national collections of satellite images, geological and topographical maps, and boundary datasets. The metadata was mapped to the ISO19115 standard and exposed via a GeoNetwork instance, enabling dynamic access from multiple internal sources. The project was a collaboration between Geoscience Australia and ANDS, with deployment supported by AuScope.

Use Cases

• Analyze land cover and environmental changes based on national satellite image collections mentioned in the description
• Map geological resources and hazards based on geological and topographical map collections
• Study maritime or administrative boundaries based on the boundary datasets referenced
• Integrate multi-source geoscientific data for decision support based on the standardized metadata mapping

Strengths

• Metadata is mapped to the ISO19115 international standard, promoting interoperability
• Data is sourced from two significant internal catalogues of a national geoscience agency
• The system enables dynamic mapping from multiple independent catalogues without a full migration

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
