Full access is available through the combination of the Voyage Data and Vessel Events services.
In order to start viewing the Past Track, you simply need to go to a vessel record or click on a vessel on the Live Map and click on Past Track. You can see a visualisation of the weather and of vessel events.
Below you can find an example for the vessel Emma Maersk.
Logged-out users can see Past Track history for up to one day in the past, while logged-in users for up to three days in the Past. More history will become available upon purchasing the Voyage Data service.
All users have access to a vessel’s past track, which is indicated via a coloured track based on the speed of the vessel along the route.
The colour of the speed is based on the following gradient.
It is also easy to identify areas with coverage gaps of over 3 hours, as they are indicated with a dashed line instead of a continuous one.
Moreover, all logged-in users (including users of our free Basic plan) also see the waypoints along the vessel track with the same colour and an arrow based on the course (or heading if the speed is below 2 knots) of the vessel at each respective position.
If you hover over each position, you will be able to see the speed, course, and timestamp at each waypoint.
Weather visualisation
Subscribers to our Voyage Data service, are also able to see another colour contour encompassing the track line. This contour displays the weather conditions (wind speed) at the respective timestamp of each position, according to the below gradient.
Across the inner side, there are corresponding wind barbs indicating the speed, direction, and strength of the wind. The corresponding barbs are based on the speed of the above gradient. You may also find more information about them here.
Vessel Events visualisation
If you are subscribed to our Vessel Events service you can also see all identified events along the vessel past-track all.
These events are indicated with an ‘i’ and distinguished in importance by colour as follows.
- Green is for low importance informational events, such as crossed strait, timezone changed etc
- Orange is for medium importance events, such as port/berth calls, vessel back in range etc
- Red is for high importance events, such as destination/ETA updates, sailing in high winds, user events etc.
Subscribers of either service will also notice that they are now able to follow the vessel as the Live Map refreshes when Past Track remains open, so that both the vessel position and the Past Track will be up-to-date on our Live Map.
For better visualisation of the Past Track, you may consider enabling our Dark Map. You can find more information and instructions on the following Article:
Past Track can also be used together with the Playback service.
