        {40.7, -120.95},
        {43.252, -126.453},

    fmt.Printf("%s\n", EncodeCoords(coords))

}

Decoding example

func ExampleDecodeCoords() {
    buf := []byte("_p~iF~ps|U_ulLnnqC_mqNvxq`@")
    coords, _, _ := DecodeCoords(buf)
    fmt.Printf("%v\n", coords)
    // Output: [[38.5 -120.2] [40.7 -120.95] [43.252 -126.453]]
