Australian Offshore Greenhouse Gas Assessment Permits, 5-Minute Graticular Blocks

Geoscience Australia Data provides a web service containing Petroleum Titles and Permits granted under the Offshore Petroleum Greenhouse Gas Storage Act 2006. The data is sourced from the National Offshore Petroleum Titles Administrator (NOPTA) and regulates activities in Commonwealth waters beyond 3 nautical miles. Title boundaries are based on 5-minute graticular blocks determined by the Australian Geodetic Datum.

Use Cases

• Mapping offshore greenhouse gas assessment permit boundaries based on the 5-minute graticular block system.
• Analyzing the spatial distribution of petroleum titles for regulatory compliance under the Offshore Petroleum Greenhouse Gas Storage Act 2006.
• Supporting environmental impact assessments for carbon capture and storage (CCS) projects in Commonwealth waters.
• Integrating permit data with other geospatial layers for resource planning and management.

Strengths

• Data is sourced from the authoritative National Offshore Petroleum Titles Administrator (NOPTA).
• Spatial boundaries are defined using a standardized 5-minute graticular block system based on the Australian Geodetic Datum.
• Covers Commonwealth waters, typically beyond 3 nautical miles from the coast.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
