JEITA CP-3451 - 50 - Type = RATIONAL Count = 1 Default = none GPSImgDirectionRef Indicates the reference for giving the direction of the image when it is captured. 'T' denotes true direction and 'M' is magnetic direction. Tag = 16 (10.H) Type = ASCII Count = 2   Default = 'T' 'T' = True direction 'M' = Magnetic direction Other = reserved GPSImgDirection Indicates the direction of the image when it was captured. The range of values is from 0.00 to 359.99. Tag = 17 (11.H) Type = RATIONAL Count = 1 Default = none GPSMapDatum Indicates the geodetic survey data used by the GPS receiver. If the survey data is restricted to Japan, the value of this  tag  is  'TOKYO'  or  'WGS-84'.  If  a  GPS  Info  tag  is  recorded,  it  is  strongly  recommended  that  this  tag  be recorded.   Tag = 18 (12.H) Type = ASCII Count = Any Default = none GPSDestLatitudeRef Indicates whether the latitude of the destination point is north or south latitude. The ASCII value 'N' indicates north latitude, and 'S' is south latitude.   Tag = 19 (13.H) Type = ASCII Count = 2 Default = none 'N' = North latitude 'S' = South latitude Other = reserved GPSDestLatitude Indicates  the  latitude  of  the  destination  point.  The  latitude  is  expressed  as  three  RATIONAL  values  giving  the degrees, minutes, and seconds, respectively. If latitude is expressed as degrees, minutes and seconds, a typical format would be dd/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 dd/1,mmmm/100,0/1.
