Geofencing with zones

A geofence or geographic zone is a virtual perimeter for real-world geographic areas. T.Rodon operators can specify a set of boundaries such as urban areas, cities, or any other geographical areas on the map to control activities in this area.

Based on a predefined area, TASSTA can offer several algorithms for dispatching a fleet – for example, locate and assign the closest eligible user in a particular area. Use zones as a border crossing control or unit positioning aid. They can be used to manage the optimal routes by work area or geographical location of the orders. Furthermore, the dispatcher can specify the route or control points on the map to perform route control for a particular unit and define a schedule.

Geo-zone functionality makes it possible to provide a number of services:

  • Track users' positions in each zone, observe their queue positions in the zone
  • Get notifications about users crossing zone borders, send messages to a group if a user leaves or enters a specific zone
  • Communicate, send messages, assign tasks to specific users (such as drivers) located in the zone
  • Create dynamic groups of users located in the same geographical location
  • View a list of all created zones

To view a list of existing zones, toggle the Zones button in the toolbar of the Map Tools window.

Define a new zone

To define a zone, go to edit mode and click the appropriate shape button in the drawing toolbar: Draw a polygon zone, Draw a circle zone or Draw a rectangle zone. Then draw the specified shape in the map area:

  • For a polygon zone, click to place the points you need, and click the last point you created to finish.
  • For a rectangle zone, click once to place a corner and click again to place the the diagonally opposite corner.
  • For a circle zone, click once to place the center of the circle, move the mouse to set the radius, and click again to finish.

For details about editing existing zones, see Edit mode.

To delete a zone, right-click it and select Remove.

Define zone properties

A zone on the map has a set of configurable options that define how it is used. To edit them, go to edit mode, right-click a zone on the map or zone list and select Properties. The options are organized into the following tabs in the zone properties dialog box:

  • General
  • Zone management
  • Notifications
  • Lone worker

General

  • Zone name
    To make the name of a zone meaningful, consider including reference information such as postal code, district or city.
  • Stroke color
  • Stroke opacity
  • Stroke width
  • Fill color
  • Fill opacity
  • Calls enabled
    Select this to be able to talk to users in the zone.
  • Static Call
    Select this to map this zone to a specific channel, and select that channel in the drop-down list.
  • Dynamic Call Timeout (sec)
    This value is used if Static call is disabled; this is how long this zone's dynamic channel can remain silent (meaning, nobody presses PTT) before the dynamic call is interrupted.

To talk to users associated with a zone, click and hold that zone. One of the following happens:

  • If Static call is enabled, you start talking in the channel selected for that option in the properties, as if you have selected that channel and pressed PTT.
  • If Static call is disabled, a dynamic group is created on the spot, all users currently inside that zone join the group, and you start talking in that group.

Zone management

You can monitor a zone for user presence and receive real-time notifications about users crossing the boundaries of the zone.

  • Accept zone control
    Click to be granted zone manager rights.
  • Channel IN
    Notify the specified channel whenever a user enters the zone.
  • Channel OUT
    Notify the specified channel whenever a user leaves the zone.
  • Disable channel change
    Prevent users from changing channels while they are inside the zone.
Important:

The notifications you set up will work only if you have clicked Accept zone control.

Notifications

This tab lets you configure notification rules for all aspects of a user's presence in the zone. Each of the following types of rules can be configured separately:

  • Passing in
    Notify when the user enters the zone.
  • Passing out
    Notify when the user leaves the zone.
  • Check if empty
    Notify when there are no users left in the zone.
  • Stay time
    Notify when the user has stayed in the zone for the specified time or longer.
  • Connect
    Notify if the user connects to the TASSTA server while inside the zone.
  • Disconnect
    Notify if the user disconnects from the TASSTA server while inside the zone.
Note:

If a user leaves one zone and enters another while disconnected and then connects from the new zone, the missing "passing out" and "passing in" notifications are generated appropriately during the connection.

Important:

The notifications you set up will work only if you have clicked Accept zone control on the Zone management tab.

Lone worker

Here you can select how a user's lone worker protection configuration changes in the zone by setting the Enable LW for users in zone to one of the following:

  • Enable
    The LWP features you specify become enabled.
  • Disable
    LWP features become disabled.
  • None
    The states of LWP features for the user do not change.

If you select Enable, you can select which individual LWP features you want to activate in the zone:

  • Periodic check
  • Man down
  • Movement
  • Track battery level
  • Detect impact
Important:

Your changes to LWP configuration will take effect only if you have clicked Accept zone control on the Zone management tab.

Applies to

If you select Enable, tracking of zone-related activity is turned on only for those users that you select on this page; activity of other users is ignored.

Saving zone configurations

You can export geo-zone data to a file. The GeoJSON format is used for the purpose; this is the standard format for encoding a variety of geographic data structures.

To export geo-zone data, use the File | Export geo data action in the menu of the Map Tool window.

Note:

Loading of geo-zone data is not supported at this time and will be available in a future release.
