This tool allows you to play tracks of moving units. There are four ways to build a track:
The most recently built track (on any tab) is selected in the Track Player automatically. However, you can switch tracks manually by choosing them in the drop-down list. The track is named after the unit it was built for, and the tab on which it was built is indicated in parentheses.
The map can be moved manually or automatically. This setting is adjusted with the icon. If this option is disabled, you can only move the map manually. If it is active, the map moves automatically in the following cases:
If messages from the unit contain pictures, you can show or hide them during playback using the icon.
Select appropriate playback speed from the drop-down list. It can vary from real-time speed (1x) to accelerated 1000 times (1000x, that is about 16 minutes of messages played in one second). Regardless of the selected value, messages with zero speed and no movement are played as fast as possible. If you change the playback speed while playing the track, a new value will be applied after you press Pause and then Play again.
Playback speed is rather conditional. Playback performance depends on the type of browser in use, computer processing power, number of messages in the track, and time intervals between the messages. In any case, all messages are played even if it takes more time.
You can play tracks both in the Tracks panel and Track Player.
To start playing, click on the button. Press the button to stop. When the playback is completed, the unit stays in the point of its last location.
When playing a track on the map, a unit icon and/or an arrow of the movement direction (depending on the selected unit presentation method) are shown. It is convenient to use rotating icons. The name of the unit whose track is being played is coloured in purple. While playback is performed, the real unit temporarily disappears from the map.
During playback, the address and speed for each message are displayed under the unit name, and the date and time are displayed above the timeline. Besides, if you have Google or Yandex keys, you can track the movement of units along real streets. To do this, expand the Google Street View or Yandex Panorama sections located below.
In two lower sections, you can see the changing values of parameters and sensors (visible sensors only). Expand these sections to see the full list. To track only certain parameters and sensors, move them to the main section of the player. To do this, double-click on necessary items.
As the track is played, all data in these sections is updated according to the message being played at the moment. If there are images in messages, they appear in the pop-up window.
To navigate through the track, click on any place of the timeline or track itself. In addition, you can use the following buttons:
You can also use a special app Track Player. This application allows you to play tracks of several units at once.
