#
# Description:  Example ExifTool print format file to generate a GPX track log
#
# Usage:        exiftool -p gpx.fmt -ee3 FILE [...] > out.gpx
#
# Requires:     ExifTool version 10.49 or later
#
# Revisions:    2010/02/05 - P. Harvey created
#               2018/01/04 - PH Added IF to be sure position exists
#               2018/01/06 - PH Use DateFmt function instead of -d option
#               2019/10/24 - PH Preserve sub-seconds in GPSDateTime value
#
# Notes:     1) Input file(s) must contain GPSLatitude and GPSLongitude.
#            2) The -ee3 option is to extract the full track from video files.
#            3) The -fileOrder option may be used to control the order of the
#               generated track points when processing multiple files.
#            4) Coordinates are written at full resolution.  To change this,
#               remove the "#" from the GPSLatitude/Longitude tag names below
#               and use the -c option to set the desired precision.
