Duplicate notification after " entered " geofence

[GISOman]

Hi everyone,

I'm working on a send alerts throw E-mails when a car has enter the geofence.

To do that I have INPUT as IVMS data then we have FILTER ( geometry enter geofence ) and that will give us an OUTPUT as E-mails.

But I facing a problem that when the car dosen't enter the geofence and stay inside (not exit) the geofence and the data refreshed in IVMS database I got the same e-mails over and over again from the same car.

I just want one e-mail when the car enter the geofence even if it is not get out from the geofence.?

Use an incident detector instead of the filter to detect 'enter' and 'exit' conditions. After, the incident detector, add a filter that only allows Status=Started.
