Playback is a unique feature that enables you to replay all vessel activity in a specific area at any given time in the past.
Alternatively, you can also use the Past Track tool in order to view a vessel’s previous route on the Live Map.
In this article you will learn about the following:
Activating Playback on the Live Map
To use the Playback feature, click on the Playback icon on the Live Map Toolbar.
Clicking on the Playback icon will prompt the Area Playback control box to come up.
You can then zoom in the desired area, select a starting time and a duration and then start the playback to view all vessel activity. For this to work, you have to make sure that the zoom level is 10 or higher. You can check the zoom level in the address bar.
Alternatively, you can:
- Select your fleet. This option will replay the tracks of all the vessels included in the fleet you have selected. The map will automatically zoom to display all the vessels of the fleet.
- Select vessels. Search and select a specific vessel to replay the tracks. If more than one vessel is selected, the map will automatically zoom out as much as needed to display all the vessels of the list. Please keep in mind that the number of vessels you can view simultaneously depends on the Vessels Historical Track allowance of your subscription level.
- Demo. Select one of the preset playback demos to review the capabilities of the tool. The demos available include some indicative cases where a playback may be required, such as high traffic areas, port close-ups, regattas, and incidents.
Once you are in the Playback Mode, another menu will appear that will allow you to:
- fast forward the vessel's movement by clicking on the plus (+) sign.
- slow down the vessel's movement by clicking on the minus (-) sign.
- reverse the vessel's activity, and see them moving backwards, by clicking on the two arrows sign.
Furthermore, you can select whether you want the tracks, the names of the vessels or the speed to be displayed, by ticking the appropriate box.
Playback is designed to support incident review, pattern analysis media reports, regatta racing observation and any application based on historical tracking data. You may take your time to explore the infinitive possibilities with Playback!
Note I: Guest users will be allowed to view any of the available "Demos" and a playback of a single vessel. Logged-in users who have not purchased the playback service, apart from the Demos, will be able to select a fleet and see the playback for a duration of 2 hours for the previous day.
Playback via Past Track
Playback can also be used together with the Past track tool.
Every time you display a vessel's past track on the Live Map, the Show Track Options toolbar is brought out. Click on it and you will be able to get animated vessel tracks by simply clicking on the Play button.
You are able to select different track lengths by defining alternate time-frames. While the SELECT TIME PERIOD tab is enabled, use the From: and To: fields to easily define your desired time-frame from the calendar that pops-up.
Note: The available track length depends on your Plan or Online Service.
Once the playback starts you will be able to use a set of controls which will enables you to further personalise the way you will be viewing it:
- You may tick the selection box next to the Show Track option to be able to see the vessel's relative position in comparison to her recorded vessel tracks
- From there, select the speed of the animated playback from the drop-down menu next to the Speed option (ranging from real-time to x1440)
- Click on the Zoom on track option to quickly re-focus on the vessel's track in case you have moved around the Live Map
- Click the Replay button to replay the animation when it ends.
- Click on the Back Arrow button to return to the initial options panel.
- Click on the X to close the Show Track Options toolbar
Note: You can get the control panel retracted at any time by clicking on the Hide Track Options button. Right-click on the Live Map to make vessels' tracks and track options disappear.
