Polygon Alarms Completed

I have completed the changes to enable polygon alarms. You can now enter a latitude, longitude and radius for each alarm. The software will require the incoming message to have LAT...LON information.

If the message has this information, the software will determine if your latitude and longitude are inside the polygon. If not, it will then get the distance your latitude and longitude are from the nearest edge of the polygon. If it is within the radius you specified, the alarm will trip.

This feature will require careful testing. It will also require users to have a good understanding of polygon warnings. This capability requires that the incoming messages be properly coded.
