Geofences can be used to define areas of interest. This may be a simple
placemarker to associate a particular location with a meaningful name,
such as Depot or Customer X.
In addition, vehicle movements both in and out of geofenced areas can be logged, alerted,
and reported on.
Circular Geofences
Circular geofences can be created with a defined radius, centred on a specific latitude and
longitude. We provide a number of different ways of creating a new circular geofence:
- Centre on a postcode
- Draw a circle on a map
- Use an existing location visited by a device
- Enter the lat and lon
By default, geofences are represented as circles on the maps which can be useful to determine the actual extents of the geofence.
We also allow geofences to be represented by an icon instead though, which is more appropriate when the presence of a geofence
is more signifant than the size, such as an office or distribution centre.
Polygonal Geofences
Polygonal geofences can be created where circular geofences are not appropriate. For example,
an irregular shaped geofence can be created around a storage compound, where accurate logging
is required, but the compound is spread over a large area and a circular geofence would be too large.
Another benefit of polygonal geofencing is to identify when vehicles enter congestion charging
zones, such as the one in London.
