gpscorrelate [-g file.gpx] [option...]
This manual page documents briefly the gpscorrelate and gpscorrelate-gui commands.
This manual page was written for the Debian(TM) distribution because the original programs do not have a manual page. Instead, they have documentation in HTML format; see below.
gpscorrelate is a program that acts on digital photo in JPEG format filling EXIF (Exchangeable Image File Format) fields related to GPS (Global Positioning System) information. Source for the GPS data is a record of GPS information encoded in GPX (GPS Exchange Format) Format. The act of filling those fields is referred to as correlation.
If GPS data are available at the precise moment the photo was taken (with a 1-second granularity) the GPS data are stored unmodified in EXIF fields. If they are not linear interpolation of GPS data available at moments before and after the photo was taken can be used.
gpscorrelate is a command line tool implementing correlation whereas gpscorrelate-gui is the corresponding GTK+ graphical user interface.
These programs follow the usual GNU command line syntax, with long options starting with two dashes (-). A summary of options is included below. For a complete description, see the HTML documentation.
-g, --gps required, specifies GPX file with GPS data -z, --timeadd +/-XX[:XX] time to add to GPS data to make it match photos. GPS data is in UTC; photos are not likely to be in UTC. Enter the timezone used when taking the photos: eg, +8 for Perth -i, --no-interpolation disable interpolation between points. Interpolation is linear, points are rounded if disabled -v, --verbose show what has been selected -d, --datum datum specify measurement datum. If not set, WGS-84 used -n, --no-write do not write the exif data. Useful with --show -m, --max-dist time max time outside points that photo will be matched. Time is in seconds -s, --show Just show the GPS data from the given files, if it exists -o, --machine Just show the GPS data from the given files, machine readable output -r, --remove Strip GPS tags from the given files, and then quit -t, --ignore-tracksegs Interpolate between track segments too -M, --no-mtime Do not change mtime of modified files -h, --help Show summary of options.
The documentation of gpscorrelate and gpscorrelate-gui in HTML format are available on the filesystem at /usr/local/share/doc/gpscorrelate/html/.
