SeaVision Playback gives the users the ability to view animated playback of historical vessel positions over a period of time between one hour and 30 days.  Users are given the ability to scroll through selected time periods to view and analyze vessel data of the selected geographic area. SeaVision Playback  can be used in conjunction with vessel filters, quick filters and extended map filters.     

Playback is located in the left menu under Map Tools.  Click the edit pencil next to “Time Machine” to open the time machine tool.  The Time Machine menu will appear at the bottom of the screen.  Select the Playback tab.
