Track is a line drawn on the map to show how a unit moved during the indicated period. A track is mapped by the points from where messages came. Each point stores also date and time when the message was received and coordinates at the point as well as other parameters (speed, sensors etc.). Besides, markers indicating places of fuel fillings, parkings and other events can be drawn on the track.
Any number of tracks can be drawn on the map. They can represent different units and various time intervals. To prevent tracks from being confused with each other, you can set different colors for them. Besides, different segments of the track can be of different colors depending on speed or sensor values.
To open the Tracks panel, choose a corresponding name in the top panel or click on the necessary item in the main menu customizer.
To build a track, it is necessary to possess the 'Query reports or messages' right towards a corresponding unit.
To build a track in the Tracks panel, do the following:
Note that in order tracks to be displayed on the map you should check if the corresponding layer icon in the main menu is active.
The principle of interval adjustment is the same as in reports (see Query and View Reports). The third and fourth steps can be united into one if you choose one of the 'quick intervals' (the buttons Today, Yesterday, Week, and Month).
A point-to-point track built according to preset parameters will appear on the map (if unit has any messages with coordinates for the period). If it takes too long for the track to appear on the map, it may mean you have indicated an interval that is too long or your Internet speed is too low.
If within the indicated period the unit was not moving, there will be no track on the map, however, it will be in the list of tracks below, and the distance traveled will be 0 km.
Alternative methods to build a track on the map are:
When mapping a track you can get a dashed line that means that some track coordinates are doubtful. It may occur if there were no coordinates at all or they were invalid. This situation may be caused by connection loss or poor satellite visibility. Connection loss is detected according to the parameters set in unit properties on the Advanced tab (see the options 'Maximum interval between messages' and 'Minimum satellites').
A track or its part can be displayed on the map as a dashed line. Such situation indicates that this part of the track might be imprecise. The cause of this can be one of the following:
After you have built a track, it is impossible to change its parameters (time, unit, color, annotations). In case of error, delete incorrect track and create a new one.
A track color depends on unit settings (see Unit Properties ⇒ Advanced). There are three alternative color settings available: 'By Speed', 'By sensor' and 'Single'. Initially, one on these settings is chosen for a unit. If the setting is not specified, then track color is single. Track color for a single track is chosen before every track building. If a color is not specified in the color range, then a new color for every new track is chosen automatically from the color range going circle-wise. Also, if a unit has 'Single' color setting and you have chosen the other color from the color range manually, then a new color will be automatically chosen from the color range going circle-wise for every next track.
Indicate track width in pixels (from 1 to 15). Track can be represented as a number of not connected points (from where messages were received) — for this choose the option Points only.
Markers in tracks are unavailable if a user has no access to reports.
You can enable markers to highlight places of significant happenings on the track. The choice of possible markers is the same as in reports:
Choose desired markers before building a track. To activate a marker, just click on its icon so that it became colorful. If at least one kind of marker is selected, additional marker options can be applied:
Markers in tracks are drawn and used along the same principles as markers in reports.
Indicate whether you want annotations to be displayed. Annotations are hints which are attached to each point of the track to show when (date and time) the message was received. On big zooms, information about speed becomes also available. Annotations are rather informative but they make visual reception of track more complicated. That is why it is reasonable sometimes to switch them off. Full information about any point of the track can be obtained from the tooltip that appears when you hover the cursor over a point. Measurement system in annotations depends on current user's settings.
Trip detector flag affects distance value and track visualization. For example, in places of stops and parkings there will be just one point instead of conglomeration of points, and the mileage will include just intervals detected as trips. Trip detector is set up in Unit Properties ⇒ Trip Detector.
Mileage in tracks can sometimes differ from mileage in reports (if there are invalid messages within the interval). In such cases, more accurate mileage is provided in reports.
You can add tracks on any unit for any time interval. The list of tracks created will be displayed in the work area at the left. To prevent tracks merging, select different colors for them.
Hover the cursor over track to get accurate information about track point (points where messages were received). Messages are searched in the radius of 50 pixels to the cursor. Points found are highlighted by a pulsating circle, and a tooltip appears with the following information: time, address, speed, altitude, coordinates, satellites, and sensor values. Messages with zero speed are marked with bigger points. Measurements used in the tooltip are borrowed from unit's properties (speed in kilometers or miles per hour, altitude in meters or feet) as well as mileage in the list of tracks.
You can manage tracks in the left part of the window under the Show Track button. Unit name is displayed on the list as well as time interval and traveled mileage. Mileage in tracks can sometimes differ from mileage in reports (if there are invalid messages within the interval). In such cases, more accurate mileage is provided in reports.
It is possible to view all created tracks on the map simultaneously or select just some of them. The tracks marked with flags are displayed. Unmark a track to hide it. Using the checkbox in the header, you can select/unselect all tracks at once. You can temporarily hide all tracks by disabling the corresponding layer in the top panel.
If there are several tracks available, you can sort them by length or name. To do so, click in the header of the list above mileage or name columns. Click again to reverse the sort order.
Use the arrows to quickly locate the initial/final point of the track. To see the whole track and focus the map on it, just click on its name in the list.
A track can be played. That means unit's icon will move along the track line with selected speed. Pressing the Play button against a track will open a special tool — Track Player — and playback will launch.
Moreover, a built track can be saved as a line geofence. To do so, click the corresponding button .
To delete a track, click on an appropriate button against it . Using a similar button at the header of the list, you can delete all tracks at once.
Furthermore, another special tool can be applied to a track — Hittest. It allows you to get the exhaustive information for any point of the track.
