MarineTraffic has a database of 800 million positions from different types of ships each month, 18 million ships and ports that register their movement, with details of more than 650,000 of those journeys. Since 2007 it offers case the ports take more prominence, exist even pictures of them uploaded by users of the platform.
They have 6 million visits per month, and many of them send ships photos circulating transporting freight and passengers. We just have to access the Photos section to view such content, although the ships is the map that occupies the central part of "the scene".
On the map we can see the amount of existing vessels in each area at a given time, with an option to zoom in to see details, including the type of vessel and the moving path.
Of course, we talk about journeys and registered ships, so do not expect to find the boat visiting the nearby island. Still, many millions of data to be acquired.
