Australian Marine Seismic Survey Navigation Data in KML and Shapefile Formats

Geoscience Australia maintains a collection of navigation data for marine seismic surveys conducted in Australia. The data includes original navigation files, 2003 SNIP navigation files, and digitized survey track maps, processed into an updated and cleansed collection. The data is available in KML and Shapefile formats for use in various geobrowsers and GIS applications.

Use Cases

• Visualizing seismic survey tracks over time based on the digitized survey track maps.
• Integrating seismic navigation data with other marine datasets using the industry-standard UKOOA P190 format.
• Checking and improving legacy seismic survey metadata based on the ongoing cleansing process described.
• Mapping marine resource exploration activities using the geospatial KML and Shapefile formats.

Strengths

• Data follows the industry-standard UKOOA P190 SNIP format, ensuring compatibility.
• Collection includes multiple data generations: original files, 2003 SNIP files, and digitized maps.
• Data is available in two widely-used geospatial formats: KML and Shapefile.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• The navigation data is not final and may contain errors, as stated by the provider.
• Row count is unknown, which may limit suitability assessment.
