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
