Marine Seismic Survey Navigation Files for Australian Waters

Geoscience Australia's 2014 collection of marine seismic survey navigation files includes recent openfile surveys. The spatial files are derived from cleansed P190 navigation files following the UKOOA standard and categorized into 3D exploration, 2D exploration, and 2D investigative seismic files. All marine surveys undertaken by Geoscience Australia for exploration or investigative purposes are included.

Use Cases

• Mapping offshore seismic survey coverage based on categorized shapefiles
• Analyzing navigation data quality and standards based on the UKOOA P190 format
• Visualizing survey tracks in earth browsers using the provided KML files

Strengths

• Files are categorized into 3D exploration, 2D exploration, and 2D investigative seismic types
• Industry standard metadata is preserved in the attribute tables
• Data is available in both KML and Shapefile formats for broad compatibility

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Description metadata is limited; actual data quality requires manual inspection after download
