====== Tracks ======

Gelios monitoring system allows you to recreate the route of the movement of the unit for a certain interval in the form of a track and to project it onto the map.

{{:en:a-user-guide:r37.png?1200|}}

The following functions are available on the Tracks tab:

  * Create a track of any unit for the specified interval;
  * Track color lighting depending on parameters of sensors;
  * Track color lighting depending on the speed of the unit;
  * Display of stops and control points.

=== Select an unit ===

A track is created for only one unit. In this case, all the created tracks are saved and available for viewing until they are closed by the user.

The unit for which you want to create a track must be selected from the drop-down list.

=== Time interval ===

To create a track, you must specify a time interval. Standard intervals of the system are:

  * Last hour;
  * Last day (by default);
  * Last week;
  * Last month.

It is also possible to select an arbitrary time interval using the calendar.

=== Track width ===

Use the slider to specify the track width on the map. The increased width allows you to present the track more clearly and identify areas with different color design.

=== Track color ===

You can select the track color and to specify the color for each interval of sensor values ​​(if any) or the speed of the unit.

It is first necessary to specify the track design variant:

  * Single-color – build a track without using sensor data and speed. Only one color is used;
  * Sensor – build a track using data from a specific sensor;
  * Speed ​​– build a track using speed data of the unit.

For the Sensor variant, select the sensor (if available). Depending on the type of sensor, you must create the required number of intervals and specify their limit values. For each interval, you can choose a different color from the color palette.

For the Speed ​​ variant, create the required number of intervals, specify their limit values, and choose the color.

=== Display ===

When creating a track, additional elements are displayed:

**1. Parking/Stops** – displays the stops of the unit for a certain time. A parking/stop is indicated on the map in the following way:

When you hover the cursor over the icon, additional information is displayed.

**2. Reference points** – detailed information on the state of the unit at a given time. Reference points are automatically inserted every 400 meters of the covered distance. The reference point is indicated on the map in the following way:

=== Build a track ===

When the required parameters are selected, click the **Build** button.

The route of the unit`s movement, projected onto the map, is a line constructed according to the coordinates of the tracking system. In this case, the map is positioned in such a way that the entire track can be seen.

When the track is built, the information about the constructed track is displayed in the form of a player at the bottom of the workspace, and the new tab “Player” with additional information about the track is added.

In order to reproduce the movement of the unit along the track on the map, click the button {{:ru:user-guide:tracks:track_play.png?direct|}}. To increase the playback speed, click on “1X” and select the desired playback speed.

When you click on the icon {{:ru:user-guide:tracks:track_play_inf.png?direct|}} you go to the Player tab to get more detailed information on the constructed track.

| **Important!** The dotted line on the unit track indicates that the unit went missing for more than 600 seconds (10 minutes) and eventually relocated to more than 120 meters. If the track is drawn on the map with a straight line through obstacles (houses, bridges, rivers, etc.), it means that there was a loss of communication with the unit for a time of less than 600 seconds and moving more than 120 meters.|

==== Player ====

The **Player** tab is displayed only after at least one track has been created and if it contains additional information on the track:

  * unit name;
  * Track length;
  * Time interval;
  * Reference point data: ignition, date, current speed, address.

{{:en:a-user-guide:r43.png?1200|}}

In order to replay the movement of the unit along the track on the map, click the button {{:ru:user-guide:tracks:track_play.png?direct25|}}. To increase the playback speed, click on “1X” and select the desired playback speed.

When you click on a line with data, the map is positioned on the location of the unit as of the selected moment.
