Indicates the altitude used as the reference altitude. If the reference is sea level
and the altitude is above sea level, 0 is given. If the altitude is below sea level,
a value of 1 is given and the altitude is indicated as an absolute value in
{@link #TAG_GPS_ALTITUDE}
A character string recording the name of the GPS area. The first byte indicates
the character code used, and this is followed by the name of the GPS area.
Indicates the latitude of the destination point. The latitude is expressed as three
unsigned 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.
Indicates the longitude of the destination point. The longitude is expressed as three
unsigned 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.
Indicates the GPS DOP (data degree of precision). An HDOP value is written during
two-dimensional measurement, and PDOP during three-dimensional measurement.
Indicates the latitude. 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.
Indicates the longitude. 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.
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.
Indicates the GPS measurement mode. Originally it was defined for GPS, but it may
be used for recording a measure mode to record the position information provided from
a mobile base station or wireless LAN as well as GPS.
A character string recording the name of the method used for location finding.
The first byte indicates the character code used, and this is followed by the name of
the method.
Indicates the GPS satellites used for measurements. This tag may be used to describe
the number of satellites, their ID number, angle of elevation, azimuth, SNR and other
information in ASCII notation. The format is not specified. If the GPS receiver is incapable
of taking measurements, value of the tag shall be set to {@code null}.
Indicates the status of the GPS receiver when the image is recorded. 'A' means
measurement is in progress, and 'V' means the measurement is interrupted.
Indicates the version of GPS Info IFD. The version is given as 2.3.0.0. This tag is
mandatory when GPS-related tags are present. Note that this tag is written as a different
byte than {@link #TAG_EXIF_VERSION}.
