BASTA Workshops - Data Quality Factors (16.-25.03.2021)

In March 2021, a total of four workshops on data quality factors took place over the course of two weeks. The aim was to jointly define quality factors and thresholds for marine munitions surveys.

Preliminary Results:

  • The introductory presentation to the workshop can be downloaded here.
  • The quality factors for all sensors under discussion (multibeam echsounder, side scan sonar, subbottom profiler, magnetics) are available here.
  • Based on the workflow that is described in the Quality Guideline for Offshore Explosive Ordnance Disposal we developed a preliminary flowchart that supports the definition of the quality factors for munitions surveys. It is available here.
  • We also collected some remarks on the polls that took place during the workshops and on our subsequent evaluation. It is available here.
