GEOFENCING

Geofences (GF) modify a standard device behavior based on the geographic location

Specifics of Anitra geofencing

• tailored for very advanced geofencing tasks on top of POI databases with even many thousands of items (e.g. database of past poisoning places, wind turbines, dangerous power pylons, etc)
• a dynamic geofence synchronization (when moving the tag synchronizes 100 closest geofence instances)
• geofences defined by circular (or possibly even cylindrical) zones
  • working with circles allows resolving conflicts for overlapping geofences (as the closest, the smallest)
  • altitude definition enables 3D geofencing (when higher it is considered as outside of geofence)

Geofence creation

• for configuring GF click the „geofences“ section in the device configuration screen
  • note the geofencing functionality was significantly reshaped and only devices with device firmware updated to the latest versions can use this feature.
  • if you do not see the „geofences“ section in your configuration screen please consult us if your device can possibly use this functionality

• a dedicated screen showing list of GF on the left side and a map of those on the right
• a new GF can be created using the „Add new geofence“ button

Geofence definition

• consists of
  • spatial definition (Latitude, Longitude, Radius{range, and Altitude)
  • modified behavior configuration for the geofence

• a spatial definition can be done in two ways
  • either manually in the map - „Define in the map“ option
    • set the center and drag a radius in the map
    • proceed to behavior definition
  • or using POI group – „Link to POI database“ option
    • list the existing POI group (note this requires you to have defined some POIs and POI groups previously – see the dedicated section of Anitra documentation
    • latitude and longitude definitions are used from POIs in the group and you only need to define the radius valid for all the POIs
    • save and proceed to behavior definition

Geofence behavior

• A modified geofence behavior is defined in the Geofence behavior screen. A subset of configuration parameters can be overridden within the geofence
  • day/night data collection interval
  • activity and speed triggering
  • radio buoy activation
  • communication while entering{leaving the geofence

• definition
  • a simplified configuration screen to manage geofence parameters is shown
  • currently valid configuration is displayed as a background
  • GF parameters overriding standard configuration can be set and saved
  • a similar editing logic as for standard configuration is implemented here – i.e draft modifications (blue) and already saved values (red)
    • get rid of any blue changes using blue crosses or simply closing the screen without saving the values
    • remove all red (saved) modifications using red crosses and resaving the screen

notes on navigation

• Select the GF in the left list of in the map to locate it in the map nad vice versa • Geofences can have following states o new: a geofence with spatial definition but no behavior defined yet o inactive/disabled: a complete GF definition ready to be acivated, allows temporary disabling GF and reanabling later when neded o active: only in this state the GF definition is actualy submitted to device ! • you can change the GF states using buttons („save“, „activate“, „disable“, „delete“) – a relevat buttons appear when clicking at the GF in the list o save – saves modified definition o activate – activates prepared definition and submits it to device in next communication session • access GF edit mode double clicking the geofence in the left GF column o you can manuály modify the original spatial definition retyping the values of latitude, Longitude, Radius or Altitude o you can also custom name the geofence o access behavior definition klicking a cog wheel icon o use escape to close „edit mode“
