Overview

Command line tools useful to manipulate GPX files.

Tools

gpx-cleanup

Removes from GPX file unnecessary data (e.g.: speed or course) stored by some GPS devices.

gpx-compress

Removes unnecessary chars (e.g.: white spaces) to decrease GPX file size.

Usage

Usage: command-name [options]

Options:
  -h, --help                show this help message and exit
  -i FILE, --intput=FILE    name of GPX input file, if not set stdin will be used
  -o FILE, --output=FILE    name of GPX output file, if not set stdout will be used

Tools can be easily used in pipeline:

cat input.gpx  | ./bin/gpx-fix-elevation | ./bin/gpx-cleanup | ./bin/gpx-compress > output.gpx
