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.
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})
...
Gpxgo can read/write both GPX 1.0 and GPX 1.1 files.
GPX extensions support is experimental from v1.1.0 on.
gpxinfo is a command line utility for writing basic stats from gpx files:
$ go run gpxinfo.go test_files/Mojstrovka.gpx
