Marine Seismic Survey Navigation Data for Offshore Exploration, 2014 Version

Geoscience Australia's 2014 collection of marine seismic survey navigation files, updated to include recent openfile surveys. The data is derived from a cleansed collection of P190 navigation files, which follow the UKOOA standard, and includes industry-standard metadata in the attribute tables. It is available in both KML and Shapefile formats for use in various geobrowsers and GIS applications.

Use Cases

• Mapping offshore petroleum exploration activity based on categorized 2D and 3D seismic survey tracks.
• Analyzing historical marine survey coverage and navigation paths based on the P190 file collection.
• Visualizing seismic survey data in earth browsers like Google Earth using the provided KML files.
• Integrating seismic survey metadata into GIS workflows using the attribute tables of the shapefiles.

Strengths

• Data is categorized into 3D exploration, 2D exploration, and 2D investigative seismic files, providing structured access.
• Includes extensive industry-standard metadata preserved in the dataset's attribute tables.
• Derived from a cleansed and updated collection of P190 navigation files, which suggests quality control.

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.
