Notice this section is EXPERIMENTAL and the interface may change before release.

The Replay system can be used for getting historical data from the system.

Historical AIS data for an area¶

To fetch AIS data, call the /replay/data API with the desired time period and geographical area (the area may be omitted).

/replay/data?begin=2016-02-09T10:25:00Z&end=2016-02-09T15:25:00Z&area=〈geojson〉&format=〈format〉 GET

The area parameter, if present, must be of type Polygon.

If the format parameter is not present, or is set to text, the return value is:

{ "data": 〈NMEA data〉 }

If the format parameter is set to binary, the return value is:

{ "data": [ { "ts": 〈timestamp〉, "data": 〈Base64 data〉 }, ... ] }

This format is for internal use only and is not yet documented.

To fetch the track for a vessel, call the /replay/track API with the MMSI and the desired time period.

/replay/track?mmsi=123456789&begin=2016-02-09T10:25:00Z&end=2016-02-09T15:25:00Z GET

An optional foruser parameter can be used to specify a user name for debugging purposes.

Return value:

{ "records": [ { "pos":〈GeoJSON-X〉, "dst": "AIS", "origin": { "mmsi": 21900123, "region": 17, "country": 219 } }, ... ] }

To determine for which periods data is available, use

/replay/range GET

Return value:

{ "database": { "begin": 〈timestamp〉, "end": 〈timestamp〉}, "filestore": { "begin": 〈timestamp〉, "end": 〈timestamp〉} }
