With a vessel selected, a day of AIS information will look like this or similar.
If the Analyze Path button is selected, then individual AIS points are available for further interrogation and will look like this.
When an individual AIS point is selected, information will be shown as depicted below.

Download Path XLS#
This will download the AIS information from the selected date range and populate it in an Excel Spreadsheet to view outside Theia. It will include Synmax Ship ID, Timestamp, Heading, Speed, and Lat Long information. |
Show Path Playback#
This option allows you to watch an icon of the vessel traveling along the Extended Path. There are 1x, 2x, and 3x options to determine the speed at which you can view this. |
Firstly you will see the View Extended Path as shown below.
Then click the Show Path Playback button to display this view. This includes a vessel icon and a slider bar that allows you to play the last 24 hours of AIS data.
By clicking the Start button, the vessel icon will move along the Extended Path. There are also options to speed up this view by clicking the dropdown menu within the slider bar. |
To close this view, please click Hide Path Playback button within the vessel toolbar. |
View Satellite Image#
When zoomed in to a vessel location, toggle this to get the full image overlay in Theia. |
When zoomed in on an individual vessel, select that vessel by left-clicking on it. An example is shown below.
A thumbnail of the vessel is visible within the vessel toolbar. However, to view the satellite image fully within the main screen, please click the View Satellite Image button. This results in the satellite image being visible, as below.

Ship to ship (STS) / Bunkering#
When the workspace icon is selected and accessed, there is a tick box for ‘Show Bunkering Only’.
Once this box is ticked, this will be the only remaining vessel icon (with a corresponding color) on the Theia display. This indicates that Theia has detected and attributed two or more vessels side by side. This is particularly useful when identifying potential illegal activity between vessels. |
