[![GoDoc](https://pkg.go.dev/badge/github.com/twpayne/go-gpx)](https://pkg.go.dev/github.com/twpayne/go-gpx)

Package `gpx` provides convenince methods for reading and writing GPX documents.

## Read example

```go

r := bytes.NewBufferString(`

    

    

        

        44.586548

        2001-11-28T21:05:28Z

        5066

        5066

        Crossing

        Crossing

        

    

`)

t, err := gpx.Read(r)

if err != nil {

    fmt.Printf("err == %v", err)

    return

}

fmt.Printf("t.Wpt[0] == %+v", t.Wpt[0])

// Output:

// t.Wpt[0] == &{Lat:42.438878 Lon:-71.119277 Ele:44.586548 Speed:0 Course:0 Time:2001-11-28 21:05:28 +0000 UTC MagVar:0 GeoidHeight:0 Name:5066 Cmt: Desc:5066 Src: Link:[] Sym:Crossing Type:Crossing Fix: Sat:0 HDOP:0 VDOP:0 PDOP:0 AgeOfDGPSData:0 DGPSID:[] Extensions:}

```

## Write example

```go

g := &gpx.GPX{

    Version: "1.1",

    Creator: "ExpertGPS 1.1 - http://www.topografix.com",

    Wpt: []*gpx.WptType{

        {

            Lat:  42.438878,

            Lon:  -71.119277,

            Ele:  44.586548,

            Time: time.Date(2001, 11, 28, 21, 5, 28, 0, time.UTC),

            Name: "5066",

            Desc: "5066",

            Sym:  "Crossing",

            Type: "Crossing",

        },

    },

}

if _, err := os.Stdout.WriteString(xml.Header); err != nil {

    fmt.Printf("err == %v", err)

}

if err := g.WriteIndent(os.Stdout, "", "  "); err != nil {

    fmt.Printf("err == %v", err)

}

// Output:

//
