OpenLR for Go

This library contains an OpenLR implementation for Golang.

A Zero dependency Golang implementation for OpenLR™ binary physical formats according to the White Paper and the reference implementation.

The OpenLR specification can be found at OpenLR.org.

Currently only supports line encoding to binary and go version 1.18+

Usage

Installation

go get -u https://github.com/uber/openlr-go

Encode Line Location Reference

package main

import (
    b64 "encoding/base64"
    "fmt"
    "github.com/uber/openlr-go/location"
)

func main() {
    llr := location.LineLocationReference{
        Poffs: 0,
        Noffs: 0,
        Points: []location.LocationReferencePoint{
            location.LocationReferencePoint{Lat: 48.0632865,
                Lon:    9.9750602,
                Frc:    1,
                Fow:    3,
                Bear:   298,
                Lfrcnp: 1,
                Dnp:    88},
            location.LocationReferencePoint{Lat: 48.0632865,
                Lon:    9.9750602,
                Frc:    1,
                Fow:    3,
                Bear:   298,
                Lfrcnp: 7,
                Dnp:    0},
        },
    }
    encodedBinary, _ := llr.Encode()
    fmt.Println(b64.StdEncoding.EncodeToString(encodedBinary))
}

This produces the following output
