Here's an example:
----8<----
package main
import (
"log"
"os"
enckml "github.com/twpayne/go-geom/encoding/kml"
"github.com/twpayne/go-geom/encoding/wkbhex"
"github.com/twpayne/go-kml"
)
func main() {
g, err := wkbhex.Decode("000000000140000000000000004010000000000000")
if err != nil {
log.Fatal(err)
}
e, err := enckml.Encode(g)
if err != nil {
log.Fatal(err)
}
if err := kml.KML(kml.Placemark(e)).Write(os.Stdout); err != nil {
log.Fatal(err)
}
// Output:
// <?xml version="1.0" encoding="UTF-8"?>
// <kml xmlns="http://www.opengis.net/kml/2.2
"><Placemark><Point><coordinates>2,4</coordinates></Point></Placemark></kml>
}
