Marine Seismic Survey Navigation Files for Offshore Exploration, 2014 Version

Geoscience Australia released the 2014 version of its Marine Seismic Surveys Shape and KML files. The collection includes 3D exploration, 2D exploration, and 2D investigative seismic files, created from a cleansed and updated set of P190 navigation files following the UKOOA standard. The data is available for download in both KML and Shapefile formats.

Use Cases

• Visualizing marine seismic survey tracks based on the provided KML and Shapefile formats.
• Analyzing the spatial distribution of offshore exploration activities based on the categorized 3D and 2D survey files.
• Integrating seismic navigation data with other geospatial datasets based on the industry-standard metadata preserved in the attribute tables.

Strengths

• Data is categorized into 3D exploration, 2D exploration, and 2D investigative seismic files.
• Extensive industry-standard metadata is preserved in the attribute tables.
• Collection is based on P190 navigation files following the UKOOA standard.

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.
