Go library to parse gpx files
So far it only maps gpx file to a struct (as defined in http://www.topografix.com/GPX/1/1) and is able to count track total distance.
Usage:
import "github.com/rndz/gpx"
func main() {
g, err := gpx.ParseFile("file.gpx")
if err != nil {
panic(err)
}
// Print track distance(km).
fmt.Println(g.Distance())
// Use track point information
for _, track := range g.Trk {
for _, segment := range track.Trkseg {
for _, pt := range segment.Trkpt {
// Do something with pt.Lat, pt.Lon, etc...
}
}
}
}

Types ¶
type Bounds ¶
type Bounds struct {
MinLat float64 `xml:"minlat,attr"`
MinLon float64 `xml:"minlon,attr"`
MaxLat float64 `xml:"maxlat,attr"`
MaxLon float64 `xml:"maxlon,attr"`
}
Bounds is two lat/lon pairs defining the extent of an element.
type Copyright ¶
type Copyright struct {
Author string `xml:"author,attr"`
Year string `xml:"year"`
License string `xml:"license"`
}
Copyright represents information about copyright holder and license.
type Gpx ¶
type Gpx struct {
XMLName xml.Name `xml:"gpx"`
Version string `xml:"version,attr"`
Creator string `xml:"creator,attr"`
Metadata *Metadata `xml:"metadata"`
Wpt []*Wpt `xml:"wpt"`
Rte []*Rte `xml:"rte"`
Trk []*Trk `xml:"trk"`
}
Gpx is a root node in .gpx document.
type Link ¶
type Link struct {
Href string `xml:"href,attr"`
Text string `xml:"text"`
Type string `xml:"type"`
}
Link is a link to external resource with additional information
type Metadata ¶
type Metadata struct {
Name string `xml:"name"`
Desc string `xml:"desc"`
Author *Person `xml:"author"`
Copyright *Copyright `xml:"copyright"`
Link []*Link `xml:"link"`
Time time.Time `xml:"time"`
Keywords string `xml:"keywords"`
Bounds *Bounds `xml:"bounds"`
}
Metadata holds information about .gpx file.
type Rte ¶
type Rte struct {
Name string `xml:"name"`
Cmt string `xml:"cmt"`
Desc string `xml:"desc"`
Src string `xml:"src"`
Link []*Link `xml:"link"`
Number uint `xml:"number"`
Type string `xml:"type"`
Rtept []*Wpt `xml:"rtept"`
}
Rte represents route - an ordered list of waypoints representing a series of turn points leading to a destination.
type Trk ¶
type Trk struct {
Name string `xml:"name"`
Cmt string `xml:"cmt"`
Desc string `xml:"desc"`
Src string `xml:"src"`
Link []*Link `xml:"link"`
Number uint `xml:"number"`
Type string `xml:"type"`
Trkseg []*Trkseg `xml:"trkseg"`
}
Trk represents a track - an ordered list of points describing a path.
type Trkseg ¶
type Trkseg struct {
Trkpt []*Wpt `xml:"trkpt"`
}
Trkseg holds a list of Track Points which are logically connected in order.
type Wpt ¶
type Wpt struct {
Lat float64 `xml:"lat,attr"`
Lon float64 `xml:"lon,attr"`
Ele float64 `xml:"ele"`
Time time.Time `xml:"time"`
Magvar float64 `xml:"magvar"`
GeoIDHeight float64 `xml:"geoidheight"`
Name string `xml:"name"`
Cmt string `xml:"cmt"`
Desc string `xml:"desc"`
Src string `xml:"src"`
Link []*Link `xml:"link"`
Sym string `xml:"sym"`
Type string `xml:"type"`
Fix string `xml:"fix"` // http://www.topografix.com/gpx/1/1/#type_fixType
Sat uint `xml:"sat"`
Hdop float64 `xml:"hdop"`
Vdop float64 `xml:"vdop"`
Pdop float64 `xml:"pdop"`
AgeOfGPSData float64 `xml:"ageofgpsdata"`
DGPSID uint `xml:"dgpsid"`
}
Wpt represents a waypoint, point of interest, or named feature on a map.
