Australian Marine Seismic Survey Navigation Data in KML and Shapefile Formats

Geoscience Australia provides updated navigation data for marine seismic surveys conducted in Australian waters. The collection includes original navigation files, 2003 SNIP navigation files, and digitised survey track maps, cleansed and made available in KML and Shapefile formats. The data is based on the SNIP format P190 navigation file following the UKOOA standard, with industry metadata preserved.

Use Cases

• Visualizing seismic survey tracks in geobrowsers like Google Earth based on the provided KML files.
• Conducting spatial analysis of marine survey coverage using the Shapefile format.
• Integrating legacy and updated navigation data for historical survey comparison based on the inclusion of original and 2003 SNIP files.
• Verifying and correcting survey metadata based on the preserved industry standard metadata mentioned in the description.

Strengths

• Data is available in two industry-standard geospatial formats: KML and Shapefile.
• The collection integrates multiple data sources: original navigation, 2003 SNIP files, and digitised track maps.
• Data follows the established UKOOA standard via the SNIP P190 format.

Limitations

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