Extended Data Fig. 4: Transport and energy vessel activity at sea is shown with an unprecedented level of detail by satellite mapping and deep learning.
From: Satellite mapping reveals extensive industrial activity at sea
Transport and energy vessels usually follow major routes (for example, shipping lanes). Each dot represents a detected vessel during 2017–2021. The colours represent detections matched (blue, publicly tracked) and unmatched (red, not publicly tracked) to known vessel positions from the AIS. The number of detections in each location depends on the local density of vessels, as well as the number of SAR acquisitions.
