    Coordinate coordinate1 = new Coordinate(1, 1);
    Coordinate coordinate2 = new Coordinate(5, 5);
    Coordinate[] coordinates = { coordinate1, coordinate2 };
    LineString lineString = new LineString(coordinates);
    // Create feature
    FeatureOptions featureOptions = new FeatureOptions();
    featureOptions.setGeometry(lineString);
    return new Feature(featureOptions);
}
