| 0x000b | 11 | GPSInfo | Exif.GPSInfo.GPSDOP | Rational | Indicates the GPS DOP (data degree of precision). An HDOP value is written during two-dimensional measurement, and PDOP during three-dimensional measurement. |
| 0x000c | 12 | GPSInfo | Exif.GPSInfo.GPSSpeedRef | Ascii | 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. |
| 0x000d | 13 | GPSInfo | Exif.GPSInfo.GPSSpeed | Rational | Indicates the speed of GPS receiver movement. |
| 0x000e | 14 | GPSInfo | Exif.GPSInfo.GPSTrackRef | Ascii | Indicates the reference for giving the direction of GPS receiver movement. "T" denotes true direction and "M" is magnetic direction. |
| 0x000f | 15 | GPSInfo | Exif.GPSInfo.GPSTrack | Rational | Indicates the direction of GPS receiver movement. The range of values is from 0.00 to 359.99. |
| 0x0010 | 16 | GPSInfo | Exif.GPSInfo.GPSImgDirectionRef | Ascii | Indicates the reference for giving the direction of the image when it is captured. "T" denotes true direction and "M" is magnetic direction. |
| 0x0011 | 17 | GPSInfo | Exif.GPSInfo.GPSImgDirection | Rational | Indicates the direction of the image when it was captured. The range of values is from 0.00 to 359.99. |
| 0x0012 | 18 | GPSInfo | Exif.GPSInfo.GPSMapDatum | Ascii | 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". |
| 0x0013 | 19 | GPSInfo | Exif.GPSInfo.GPSDestLatitudeRef | Ascii | 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. |
| 0x0014 | 20 | GPSInfo | Exif.GPSInfo.GPSDestLatitude | Rational | 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. |
| 0x0015 | 21 | GPSInfo | Exif.GPSInfo.GPSDestLongitudeRef | Ascii | Indicates whether the longitude of the destination point is east or west longitude. ASCII "E" indicates east longitude, and "W" is west 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. |
