Go GPX library

gpxgo is a golang library for parsing and manipulating GPX files. GPX (GPS eXchange Format) is a XML based file format for GPS track logs.

Example:

import (
    ...
    "github.com/tkrajina/gpxgo/gpx"
    ...
)

gpxBytes := ...
gpxFile, err := gpx.ParseBytes(gpxBytes)
if err != nil {
    ...
}

// Analyize/manipulate your track data here...
for _, track := range gpxFile.Tracks {
    for _, segment := range track.Segments {
        for _, point := range segment.Points {
            fmt.Print(point)
        }
    }
}

// (Check the API for GPX manipulation and analyzing utility methods)

// When ready, you can write the resulting GPX file:
xmlBytes, err := gpxFile.ToXml(gpx.ToXmlParams{Version: "1.1", Indent: true})
...

GPX Compatibility

Gpxgo can read/write both GPX 1.0 and GPX 1.1 files. The only not-yet-supported part of the GPX 1.1 specification are extensions.

gpxinfo

gpxinfo is a command line utility for writing basic stats from gpx files:

$ go run gpxinfo.go test_files/Mojstrovka.gpx
