AIS data prepared by Statsat AS for August 2020
<p>AIS data prepared and provided by Statsat AS (Norway) in the framework of the T-SAR project (<em>IKTPLUSS programme on reducing digital vulnerabilities, </em><strong>10 MNOK from the Research Council of Norway, Norway</strong>).</p> <p>The dataset contains AIS data (satellite + other) on a global coverage for 2020.
