从1套坐标和距离计算新的GPS坐标？

Question

所以我想知道是否有现有的代码/库可以让我计算给定的一对新的GPS坐标：距离，一对纬度，经度和方位。

我希望你们能给我洞察力。

干杯！

使用以下库： https : //github.com/JavadocMD/simplelatlng但是执行计算的方法如下：

/**
     * <p>
     * Calculate the end point of traveling along a great-circle path from a
     * given starting point with a given intitial bearing for a known distance.
     * </p>
     * 
     * @param start
     *            the starting point.
     * @param initialBearing
     *            the initial bearing.
     * @param distance
     *            the distance to travel.
     * @param unit
     *            the unit in which distance is measured.
     * @return the end point.
     */
    public static LatLng travel(LatLng start, double initialBearing, double distance,
            LengthUnit unit) {
        double bR = Math.toRadians(initialBearing);
        double lat1R = Math.toRadians(start.getLatitude());
        double lon1R = Math.toRadians(start.getLongitude());
        double dR = distance / LatLngConfig.getEarthRadius(unit);

        double a = Math.sin(dR) * Math.cos(lat1R);
        double lat2 = Math.asin(Math.sin(lat1R) * Math.cos(dR) + a * Math.cos(bR));
        double lon2 = lon1R
                + Math.atan2(Math.sin(bR) * a, Math.cos(dR) - Math.sin(lat1R) * Math.sin(lat2));
        return new LatLng(Math.toDegrees(lat2), Math.toDegrees(lon2));
    }
