What is a geofence?

A geofence is a virtual boundary around a site, depot or yard. Use MapTrack Telematics to see when tracked equipment arrives or leaves, review the visit and plan what happens next.

Know when equipment leaves site or returns to the depot

Use MapTrack Telematics to review the movement that matters to your next job. Start with a named site and a known device, then inspect the visit before acting on the time recorded.

  1. 1. Choose the site and equipment

    Agree which site, depot or yard you need to monitor. Confirm the tracker or telematics source for each asset and the reporting interval you expect.

  2. 2. Check the boundary against a real visit

    In MapTrack Telematics, review the site boundary alongside its access roads and loading areas. Compare a known arrival and departure with the recorded entry and exit events.

  3. 3. Review movement and follow up

    Use trip history and configured entry or exit alerts to investigate equipment arriving, returning or leaving unexpectedly. Check gaps in received updates before treating a missing event as a missing visit.

  4. 4. Keep site time in context

    Keep the asset, date range and boundary with the report. Check assignments, bookings and maintenance before reallocating equipment. Use the appropriate meter or work record when the question is engine use or work completed.

Setup and limits

  • Geofence reporting requires a configured connected device and MapTrack Telematics. The app’s latest-position view does not establish a visit history.
  • Time inside a boundary does not establish engine runtime, operator attendance or billable productive work.

What is a geofence?

A geofence is a virtual boundary around a real-world location. A connected device supplies location updates, and the software compares those updates with the boundary. In MapTrack Telematics, this gives plant and fleet teams a way to review arrivals, departures and time on site.

  • Construction site: check when tracked plant arrives and investigate an unexpected departure.
  • Depot or yard: review which tracked vehicles or trailers have returned before planning the next allocation.
  • Customer site: compare the recorded visit with the agreed job or hire period and investigate gaps.
  • Several sites: use consistent site names and periods when reviewing movement between jobs.

How does a geofence work?

The device reports a position, then the telematics system checks whether that position falls inside or outside the boundary. Entry and exit records depend on the updates received. Keep the device’s reporting interval in mind when comparing a recorded event with an arrival noted by someone on site.

  • Boundary: the site, depot or yard you want to recognise.
  • Connected device: the tracker or supported telematics source supplying location updates for the asset.
  • Event: an entry or exit identified from the received positions.
  • Follow-up: a configured alert or a visit record to review in MapTrack Telematics.

Geofence vs GPS tracking

A GPS position helps you find equipment. A geofence helps you understand its movement around a named place. The MapTrack app shows the asset’s latest received position alongside the operational record. Use MapTrack Telematics for live GPS, geofences, trips and location history.

Use the visit record to plan the next job

Start with a practical question: has the trailer returned to the depot, when did the excavator leave site, or which tracked equipment stayed at a job overnight? Review the relevant visit and trip history in MapTrack Telematics, then check the asset’s assignment, bookings and maintenance before moving it to another job. Site presence alone does not tell you whether equipment is available or ready for work.

Check a boundary before relying on its reports

Use a known arrival and departure to check the boundary, the device and the reporting interval together. Look at access roads, loading areas and neighbouring sites when investigating unexpected entries or exits. Keep the asset, period and boundary with your report so another person can understand the same visit.

The problem

You’re planning tomorrow’s jobs, but you still need to know whether a trailer is back at the depot or an excavator has left site. A latest position helps you find the equipment. To understand the visit, you need the arrival, departure and reporting period as well.

How MapTrack addresses it

MapTrack Telematics provides live GPS, geofences, trips and location history for configured devices. Review site visits and entry or exit alerts there, then use the MapTrack asset record for the latest position alongside forms, assignments and maintenance. MapTrack sells and supports both screens, with the hardware and reporting setup matched to your equipment.

How it works

  • 1

    Confirm the connected device

    Check the hardware, provider connection and reporting interval for the equipment you want to monitor.

  • 2

    Name the site or depot boundary

    Use MapTrack Telematics for geofences. Check the relevant access roads and loading areas against a known visit.

  • 3

    Review arrivals and departures

    Inspect entry and exit events, trip history and configured alerts. Investigate gaps or unexpected movement before acting.

  • 4

    Plan from the full equipment record

    Keep site presence alongside the asset’s assignments, bookings and maintenance when deciding where it should go next.

Frequently asked questions

A geofence is a virtual boundary around a real place, such as a depot, job site or customer yard. Location updates from a connected tracker let the software identify when equipment enters or leaves that area. In MapTrack Telematics, those events support alerts and time-on-site reporting.

Fit the machine with a GPS tracker and draw each site's boundary in MapTrack, as a radius or a traced area. Entry and exit alerts, trips and time-on-site reports run in MapTrack Telematics, from the same vendor and account, while MapTrack shows each machine's latest position alongside its forms and maintenance. Time on site shows presence within the boundary, not engine hours, so use meter readings for runtime.

MapTrack Telematics uses location updates from configured devices to report visits within a site boundary. Review the equipment, date range and entry and exit records together. The MapTrack app shows each asset’s latest position alongside its forms and maintenance; live GPS, geofences, trips and location history run in MapTrack Telematics.

No. Fit GPS where you need automatic location updates and geofence events. Equipment without a connected location source can still be managed through Requests, assignments and check-in and check-out. Choose the tracking method for the job and the asset.

MapTrack supports GPS hardware and telematics integrations for location and supported meter readings. Confirm the provider, hardware, data connection and required reports with MapTrack before rollout. Registering a device does not establish that every reading or geofence workflow is available from it.

GPS tracking supplies location updates. A geofence adds a named boundary so you can interpret those updates as arrivals, departures or time within a site. Check the age of each update when investigating a movement.

Configured entry or exit events can alert you when tracked equipment crosses a site or depot boundary in MapTrack Telematics. Agree which events need attention and who will receive the alerts, then test the setup against a known visit before relying on it.

Check the accuracy and reporting interval of the hardware used at your site. A boundary event depends on received location updates, so gaps or delayed updates affect the record. Compare a known arrival and departure with the reported events before using site time for planning or reconciliation.

Start with the area you need to recognise, including the entry road, loading area or depot yard where relevant. Check nearby roads and neighbouring sites, then test the boundary with a known visit. Review unexpected crossings before making the boundary tighter.

Time on site measures presence within a boundary. It does not establish engine runtime, operator attendance or billable productive work. Use the relevant meter readings, work records and agreed commercial records for those decisions.
