[OpenMap Users] Vessel Tracking System

Hi, OpenMap Gurus:

I am new to OM, we want to use OM to develop a vessel tracking system. It
should be similar to the vehicle tracking system. When the message is
received, I can extract the unique vessel ID and position coordinates
(Longitude,Latitude). My question is how to decide whether it is a new
vessel or it is already displayed on the map and only needs to be updated?

Any info or code snippet is greatly appreciated!

Best Regards

Rose Zhou
