Define your areas of interest with Geofencing

Geofencing uses polygons and associated GPS schedules to define areas of interest and their use.

  • Google Earth or the lat and long of each polygon corner defines the area
  • Automatic GPS schedule changes for ingress /egress of Geofenced areas
  • Unlimited schedule possibilities using multiple polygons & schedules
  • Alerts via satellite of animal ingress / egress of a Geofenced area

Geofencing is available in the following Lotek products:


Geofencing applications include:

  • Transmission line or highway corridors impacts
  • Forestry treatment impacts
  • Sibling or conspecific interactions
  • Sensitive area delineation
  • Predation efficiency
  • Pack or herd coherence and behaviour
  • Human / wildlife conflicts & interactions


geofencingGeofencing allows the researcher to spatially define areas of special interest and assign alternate GPS schedules for each of these spatially defined areas. Once the study animal enters or exits an area of interest, the GPS schedule changes to that defined by the researcher for that specific area. Egress from the specific area of interest triggers the original GPS sampling regime. Specific GPS sampling regimes may be defined for multiple types of areas of interest simultaneously.

Spatially defining of areas of interest and associated GPS sampling schedules using Geofencing is as easy as one, two, three:

  1. Create one or more polygons. You can edit the coordinates or draw it in Google Earth and import the polygon(s).
  2. Create a GPS schedule which will apply inside and outside the polygon
  3. Upload the virtual fence data (polygons + schedule) by cable, by GSM or by IRIDIUM

When the collar detects a valid geo fence option and detects that the collar is inside the polygon defining the geo fence option, the collar will automatically use the GPS schedule which has been uploaded together with the fence(s). When the animal has moved out of the defined polygon, the collar will use the stored “standard or old” GPS schedule.

Multiple complex shapes may be defined and along with their associated schedules may be uploaded to the collar to create a complex scheduling scenario for various aspects of a study.
