Geofencing
A virtual boundary that triggers something when an item enters or leaves it.
A geofence is an area drawn on a map that acts as a trigger: when something enters, crosses or leaves it, an alert fires or a process starts. Common uses are ships approaching a berth, vehicles reaching a site, or incidents inside a service area.
In xMap Flows, Zone alert remembers each item's last position between runs and reports what entered, crossed, is inside or left a zone you draw. It works with anything that has a position and moves: ships from Ships (AIS), or your own vehicles sent by webhook.
