DESCRIPTION

       This manual page documents briefly the gpscorrelate and gpscorrelate-gui commands.

       There is an extended documenation available in HTML format; see below.

       gpscorrelate is a program that acts on digital images 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 image 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 image was taken can be used.

       gpscorrelate is a command line tool implementing correlation whereas gpscorrelate-gui is the corresponding GTK+ graphical user interface.

OPTIONS

       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 file.gpx
	   correlate using the specified GPX file with GPS data

       -s, --show
	   only show the GPS data of the given images

       -o, --machine
	   only show the GPS data of the given images in a machine readable output, if there is any

       -r, --remove
	   only remove GPS EXIF data from the given images

       -z, --timeadd +/-XX[:XX]
	   time to add to GPS data to make it match the timestamps of the images. GPS data is in UTC; images are not likely to be in UTC. Enter
	   the timezone used when taking the images: eg, +8 for Perth

       -O, --photooffset seconds
	   time in seconds to add to the photo timestamp to make it match the GPS timestamp. To determine the amount of seconds needed, just
	   create a picture of your GPS device showing the current time and compare it with the timestamp of your photo file.

       -i, --no-interpolation
	   disable interpolation between points. Interpolation is linear, points are rounded if disabled

       -v, --verbose
	   show which GPS data has been selected for each image

       -d, --datum datum
	   specify measurement datum. If not set, WGS-84 used

       -n, --no-write
	   do not write the exif data. Useful with --verbose

       -m, --max-dist time
	   max time outside points that image will be matched. Time is in seconds

       -t, --ignore-tracksegs
	   Interpolate between track segments, too

       -M, --no-mtime
	   Do not change mtime of modified files

       -f, --fix-timestamps
	   Fix broken GPS datestamps written with versions < 1.5.2

       -p, --degmins
	   Write location as DD MM.MM as was default before < 1.5.3

       -h, --help
	   Only show summary of options

       -V, --version
	   Only print the version
