The AIS feature can draw corresponding objects on the Map.

  • Status - Status of the vessel (E.g. Underway using engine, At anchor).
  • IMO - International Maritime Organization (IMO) number which uniquely identifies a ship. Double clicking on this column will search for the IMO on https://www.vesselfinder.com/

Map

The AIS feature can plot ships, base stations and aids-to-navigation on the Map. To use, simply open a Map feature and the AIS plugin will display objects based upon the messages it receives from that point. Selecting an AIS item on the map will display a text bubble containing information from the above table. To centre the map on an item in the table, double click in the Lat or Lon columns.
