Google S2 라이브러리를 사용하여 좌표로 Geolocation을 만드는 방법

Question

Google S2 라이브러리를 사용하여 사각형을 구성 할 수 있지만 Google S2 라이브러리를 사용하여 다각형을 구성 할 수 없습니다. 다른 방법으로 다각형을 만들 수 있지만 시도 할 수는 없습니다. 만들려면 이걸 좀 도와주세요.

내 코드는 다음과 같습니다

Double point1_lat= 41.94621306986162; 
    Double point1_long = -87.85629272460938; 
    Double point2_lat= 41.91198644177823; 
    Double point2_long = -87.84427642822266; 
    Double point3_lat= 41.91173095014916; 
    Double point3_long = -87.7804183959961; 
    Double point4_lat= 41.94570235966688; 
    Double point4_long = -87.75672912597656; 
    Double point5_lat= 41.966893394601335; 
    Double point5_long = -87.78900146484375; 
    Double point6_lat= 41.97480631113838; 
    Double point6_long = -87.84049987792969; 
    Double check1 = 41.916585116228354; 
    Double check2 = -87.736129760742194; 

    // For point 
    S2Point point1 = new S2Point(point1_lat, point1_long, 0); 
    S2Point point2 = new S2Point(point2_lat, point2_long, 0); 
    S2Point point3 = new S2Point(point3_lat, point3_long, 0); 
    S2Point point4 = new S2Point(point4_lat, point4_long, 0); 
    S2Point point5 = new S2Point(point5_lat, point5_long, 0); 
    S2Point point6 = new S2Point(point6_lat, point6_long, 0); 
    S2Point point7 = new S2Point(check1, check2, 0); 

    List<S2Point> point = new ArrayList<S2Point>(); 
    point.add(point1); 
    point.add(point2); 
    point.add(point3); 
    point.add(point4); 
    point.add(point5); 
    point.add(point6); 

    System.out.println("*************** debug point 3 
     ****************" + point); 

    S2PolygonBuilder polygonBuilder = new S2PolygonBuilder(); 
    S2Loop loop = new S2Loop(point); 

    System.out.println("*************** debug point 4 
    ****************"); 
    polygonBuilder.addLoop(loop); 
    S2Polygon polygon = polygonBuilder.assemblePolygon(); 

    System.out.println("*************** debug point 5 
    ****************"); 
    S2RegionCoverer coverer = new S2RegionCoverer(); 
    coverer.setMinLevel(12); 
    coverer.setMaxLevel(12); 
    coverer.setMaxCells(100); 

    System.out.println("*************** debug point 6 
    ****************"); 


    S2CellUnion union = coverer.getCovering(polygon); 

    System.out.println("*************** debug point 7 
    ****************");

S2Point가 당신이 코드를 변경해야 얻을 :

S2Point point1 = S2LatLng.fromDegrees(point1_lat, point1_long).toPoint(); 
//new S2Point(point1_lat, point1_long, 0);
