Scala AIS message encoding and decoding library built with scodec
A typesafe library for decoding AIS messages. Special missing values (like 511 for true heading) are decoded as Option values.
Currently a proof of concept, supporting decoding only of messages types 1, 2, 3, 5, 8, 18, 19, 21, 24, 27.
import nl.vroste.ais._
val nmeaMessage = "!AIVDM,1,1,,A,13aIgm0P00PCtV6MdbFIROvP2>`<,0*4E" // This is a position report
val decodedOrError: Either[Err, AisMessage] = AisMessa.decode(nmeaMessage)
decodedOrError match {
case(Some(positionReport)) =>
println(positionReport.courseOverGround) // Will print 244.1
}
See the unit tests for more examples.
