Marine Seismic Survey Navigation Files for Australian Waters

Geoscience Australia provides a 2014 version of marine seismic survey navigation files in Shape and KML formats. The collection includes 3D exploration, 2D exploration, and 2D investigative seismic files, updated with recent openfile surveys. Data is based on P190 navigation files following the UKOOA standard, preserving industry metadata in attribute tables.

Use Cases

• Map seismic survey lines categorized as 3D exploration, 2D exploration, or 2D investigative using the shapefile attributes.
• Analyze the spatial distribution of marine surveys in Australian waters based on the P190 navigation file collection.
• Extract industry-standard metadata preserved in the dataset's attribute tables for survey cataloging and compliance reporting.
• Visualize survey tracks in applications like Google Earth using the provided KML files for public communication or education.

Strengths

• Collection includes three distinct categories of seismic files: 3D exploration, 2D exploration, and 2D investigative.
• Data is based on a cleansed, updated collection of P190 navigation files following the UKOOA standard.
• Files are available in two widely supported GIS formats: Shapefile and KML.

Limitations

• Data version is from 2014, which may not include surveys conducted in the last decade.
• Accuracy and completeness are not warranted, as stated in the provider's disclaimer.
• Sample data and specific row/column counts are unavailable for assessing dataset scale.
