Position alerts

The Position alerts flow detects whether any vessel emitted VMS data that matches the specified detection parameters on :

  • flag state

  • area of detection

  • whether to detect all positions or only positions with fishing activity (as detected by the enrich positions flow)

  • fishing gear (from logbook data and Vessel profiles)

  • species (from logbook data)

  • time window (specified by a number of hours preceding the present time)

  • depth (based on bathymetry data from https://emodnet.ec.europa.eu at the position of the VMS point)

The detected vessels are loaded to the pending_alerts table.
