GPS Tags

GPSVersionID Indicates the version of <GPSInfoIFD>.
GPSLatitudeRef Indicates whether the latitude is north or south latitude. ‘N’ indicates north latitude, and ‘S’ is south latitude.
GPSLatitude Indicates the latitude. The latitude is expressed as three values giving the degrees, minutes, and seconds, respectively.
GPSLongitudeRef Indicates whether the longitude is east or west longitude. ‘E’ indicates east longitude, and ‘W’ is west longitude.
GPSLongitude Indicates the longitude. The longitude is expressed as three values giving the degrees, minutes, and seconds, respectively.
GPSAltitudeRef Indicates the altitude used as the reference altitude.
GPSAltitude Indicates the altitude based on the reference in GPSAltitudeRef. The reference unit is meters.
GPSTimeStamp Indicates the time as UTC (Coordinated Universal Time). <TimeStamp> is expressed as three values giving the hour, minute, and second (atomic clock).
GPSSatellites Indicates the GPS satellites used for measurements. This tag can be used to describe the number of satellites, their ID number, angle of elevation, azimuth, SNR and other information.
GPSStatus Indicates the status of the GPS receiver when the image is recorded. “A” means measurement is in progress, and “V” means the measurement is Interoperability.
GPSMeasureMode Indicates the GPS measurement mode. “2” means two-dimensional measurement and “3” means three-dimensional measurement is in progress.
GPSDOP Indicates the GPS DOP (data degree of precision). An HDOP value is written during two-dimensional measurement, and PDOP during three-dimensional measurement.
GPSSpeedRef Indicates the unit used to express the GPS receiver speed of movement. “K” “M” and “N” represents kilometers per hour, miles per hour, and knots.
GPSSpeed Indicates the speed of GPS receiver movement.
GPSTrackRef Indicates the reference for giving the direction of GPS receiver movement. “T” denotes true direction and “M” is magnetic direction.
GPSTrack Indicates the direction of GPS receiver movement.
GPSImgDirectionRef Indicates the reference for giving the direction of the image when it is captured. “T” denotes true direction and “M” is magnetic direction.
GPSImgDirection Indicates the direction of the image when it was captured.
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”.
GPSDestLatitudeRef Indicates whether the latitude of the destination point is north or south latitude. “N” indicates north latitude, and “S” is south latitude.
GPSDestLatitude Indicates the latitude of the destination point. The latitude is expressed as three values giving the degrees, minutes, and seconds, respectively.
GPSDestLongitudeRef Indicates whether the longitude of the destination point is east or west longitude. “E” indicates east longitude, and “W” is west longitude.
GPSDestLongitude Indicates the longitude of the destination point. The longitude is expressed as three values giving the degrees, minutes, and seconds, respectively.
GPSDestBearingRef Indicates the reference used for giving the bearing to the destination point. “T” denotes true direction and “M” is magnetic direction.
GPSDestBearing Indicates the bearing to the destination point.
GPSDestDistanceRef Indicates the unit used to express the distance to the destination point. “K”, “M” and “N” represent kilometers, miles and knots.
GPSDestDistance Indicates the distance to the destination point.
GPSProcessingMethod 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.
GPSAreaInformation A character string recording the name of the GPS area.
GPSDateStamp A string recording date and time information relative to UTC (Coordinated Universal Time).
GPSDifferential Indicates whether differential correction is applied to the GPS receiver.
