GpxCli

Tool for mainipulation with gpx files

Merge

Allows to merge content from multiple gpx files into one single file. Merge operation does also simplification of track data

Use case - generating heat maps from hundreads of tracks in your browser is more efficient if you download preprocessed data in one file instead of fetching each gpx file separately and parsing from xml.

Examples:

Merge three gpx tracks into single file output.json (default output format is json)

./gpxcli merge track1.gpx track2.gpx track3.gpx

Merge all gpx files from gpx directory to file all.yml with custom value for minimal distance (in megetrs) between points (track simplification):

./gpxcli merge --min-distance 20 --output all --yaml gpx/*

Coordinates, in this context, are points of intersection in a grid system. GPS coordinates are usually expressed as the combination of latitude and longitude.

Lines of latitude coordinates measure degrees of distance north and south from the equator, which is 0 degrees. The north pole and south pole are at 90 degrees in either direction.

The prime meridian, located in Greenwich, UK, is 0 degrees longitude, and the lines of longitude coordinates are measured according to 90 degrees east and west from that point.
