gpxsplit

GPX Splitting Tool

gpxsplit is command line tool to split and convert GPX files.

GPX is handy, de-facto standard file format used by GPS devices and mapping software. But some legacy GPS devices are limited in way they support tracks, especially longer ones. This tool convert and split GPX files. It make possible to use modern GPX files, like those exported from on line routing sites to handle them on older, legacy GPS hardware.

Setup

• install Node.JS (if not already installed)
• from command line execute:

$ npm install -g gpxsplit 

Usage

$ gpxsplit [options] [path_to_gpx_file]

For full list of supported options execute:

$ gpxsplit -h

Options

All options are optional. When not specified, they are ignored or have default value. Boolean options are true if flag is present, false otherwise.

Option	Type	Default value
-h, --help	Boolean
-V, --version	Boolean
-s, --split	Integer	500
-w, --waypoints	Integer	10
-o, --output	File Path	auto generated
-b, --backup	Boolean
-d, --decimals	Integer [3..7]	6
-p, --postfix	String	-split
--noNameFix	Boolean
--noSplit	Boolean
--noWaypoints	Boolean

Option help

Displays all options with short description.

Option version

Displays version of application (match NPM/Git version number).

Option split

Maximal allowed count of points in track. If track have more points, it will be split into parts. Each part points count is configured by this parameter.

Track parts shares all attributes of original path, with few notable changes:

• track label and name are updated (or added - if not present), with number of part appended to it's end.
• if resulting name is longer than 13 characters - original name will be shortened to fit into 13 character limit. This behaviour can be disabled by adding --noNameFix option

If parameter is 0, track will be not split, same as when adding --noSplit.

Option waypoints

Adds waypoints (POIs) each specified amount of kilometers. If parameter is 0, no waypoints are generated, same as when adding --noNameFix.

Option output

Explicit specifies output file. If not given, original file name is used, together with option -p, --postfix, to generate output name. If output file exists it will be overwritten

Option backup

If given, this option triggers making copy of source GPX file, saved into file with appended .bak extension. Previous .bak file (old backup) will be overwritten.

Option decimals

Specify amount of significant decimal places for GPS coordinates. Should be value between 3 and 7, default 6 is usually best choice.

Option postfix

Decides postfix added to source GPX file name to generate default output GPX file name. If source file name is already postfixed with given postfix, file will be backed-up and overwritten.

Option no name fix

By default, while splitting tracks, resulting track name is shortened to fit into 13 characters limit - as it is required by some older GPS devices. But when this flag is present, name is not adjusted.

Option no split

By default, tracks having more point than threshold specified by -s, --split , are divided into parts. But when this flag is present, tracks are not split or adjusted.

Option no waypoints

By default, POIs for track distance are added to GPX But when this flag is present, no waypoints are generated.
