Open Waters AIS tools (5)

write = sends, deletes, buys or posts
  • find_vessels_in_areaFree

    Vessels currently inside a latitude/longitude bounding box, newest report first, with optional kind and ship-type filters. Use for what is in a port, a strait, or a stretch of coast. Anonymous calls may cover 100 square degrees per call.

  • find_vessels_nearFree

    Vessels within a radius (default 10 NM, maximum 50) of a point or of another vessel, nearest first, each with distance and bearing from the centre. Use for what is near this position or what is around vessel X.

  • get_coverageFree

    Where Open Waters AIS is hearing AIS right now: sources, stations, freshness, and vessel counts. Pass a bounding box to learn which stations cover it and how many vessels are in it, or a station id for that station's numbers. Call this before saying a region has no traffic.

  • get_vesselsFree

    Current position and details of specific vessels by MMSI (Maritime Mobile Service Identity): the last report heard for each, and which MMSIs have not been heard in the last 30 minutes. Use search_vessels_by_name first when you only have a name.

  • search_vessels_by_nameFree

    Vessels whose name contains the text, case-insensitive, among vessels heard in the last 30 minutes. Use to turn a name into an MMSI, then get_vessels or find_vessels_near for detail. An optional bounding box narrows the search.
