Constructor Detail

TrackDataPacket

public TrackDataPacket(GarminPacket packet)

Creates a track packet from the given packet data. If the D301 protocol supported elevations along the track will also be stored.

Parameters:

packet - Packet to copy.

Throws:

PacketNotRecognisedException - if the given packet is not a track packet.

Method Detail

getLatitude

public AngleRadians getLatitude()

Reports the latitude of the track coordinate.

Specified by:

getLatitude in interface Position

Returns:

Latitude in radians.

getLongitude

public AngleRadians getLongitude()

Reports the longitude of the track coordinate.

Specified by:

getLongitude in interface Position

Returns:

Latitude in radians.

getAltitude

public float getAltitude()

Reports the altitude of this track coordinate.

Specified by:

getAltitude in interface Position

Returns:

Altitude of this position in units determined by the GPS. May be 0 if GPS unit does not record waypoint altitude.

isFirst

public boolean isFirst()

Reports whether this is the first point in a track segment.

Specified by:

isFirst in interface GPSTrack

Returns:

true if first point.

getTime

public Date getTime()

Should report the time stamp associated with this track coordinate.

Specified by:

getTime in interface GPSTrack

Returns:

Time associated with this track coordinate.
