JEITA  CP-3451 - 51 - Tag = 20 (14.H) Type = RATIONAL Count = 3 Default = none GPSDestLongitudeRef Indicates whether the longitude of the destination point is east or west longitude. ASCII 'E' indicates east longitude, and 'W' is west longitude. Tag = 21 (15.H) Type = ASCII Count = 2 Default =       none 'E' = East longitude 'W' = West longitude Other = reserved GPSDestLongitude Indicates the longitude of the destination point. The longitude is expressed as three RATIONAL values giving the degrees, minutes, and seconds, respectively. If longitude is expressed as degrees, minutes and seconds, a typical format would be ddd/1,mm/1,ss/1. When degrees and minutes are used and, for example, fractions of minutes are given up to two decimal places, the format would be ddd/1,mmmm/100,0/1. Tag = 22 (16.H) Type = RATIONAL Count = 3 Default = none GPSDestBearingRef Indicates  the  reference  used  for  giving  the  bearing  to  the  destination  point.  'T'  denotes  true  direction  and  'M'  is magnetic direction. Tag = 23 (17.H) Type = ASCII Count = 2 Default = 'T' 'T' = True direction 'M' = Magnetic direction Other = reserved GPSDestBearing Indicates the bearing to the destination point. The range of values is from 0.00 to 359.99. Tag = 24 (18.H) Type = RATIONAL Count = 1 Default = none GPSDestDistanceRef Indicates the unit used to express the distance to the destination point. 'K', 'M' and 'N' represent kilometers, miles and knots.
