Marine Seismic Survey Navigation Files for Offshore Exploration

Geospatial files contain navigation data from marine seismic surveys conducted for offshore petroleum and greenhouse gas exploration. The collection includes 2D exploration, 3D exploration, and 2D investigative seismic surveys, standardized from P190 navigation files following the UKOOA standard. Geoscience Australia compiled and released this 2014 version, which incorporates data from regulatory submissions and digitized historical track maps.

Use Cases

• Analyze spatial distribution of 2D exploration, 3D exploration, and 2D investigative seismic surveys using survey type attributes.
• Validate survey navigation tracks against the UKOOA P190 standard for data quality assurance.
• Map historical marine seismic activity for regional offshore resource assessment using the provided KML or shapefile geometries.

Strengths

• Collection includes data checked under the Offshore Petroleum and Greenhouse Gas Storage Regulations, adding regulatory oversight.
• Data is available in both KML and Shapefile formats, supporting use in multiple geospatial applications.
• Extensive industry-standard metadata is preserved in the attribute tables of the datasets.

Limitations

• Dataset version is from 2014, making the navigation data potentially stale for current exploration planning.
• No specific row count, file size, or sample data is provided to assess the collection's scale.
• The disclaimer states no warranty for accuracy, completeness, or suitability, requiring independent validation.
