然后,您可以使用它们来构建路径(例如,SVG path)：

<svg
  ...>
  <g
     transform="matrix(1250,1250,46206.909,-217995.49)"
     ...>
    <path
       d=" M -36.76736,174.83433 L -36.93842,174.55269 A 0.08333,0.08333 0 0,1 -36.80550,174.42714 L -36.68503,174.62581 A 0.02500,0.02500 0 0,0 -36.68342,174.66586 L -36.66372,174.69231 A 0.02500,0 -36.65486,174.69992 L -36.66072,174.74381 L -36.61911,174.79094 A 0.08333,1 -36.76736,174.83433 Z"

实际上,没有API可以在GMaps / OSMDroid中创建曲线,弧等,所以你应该画几条小线.这意味着做一些数学,但这个数学可以由GeographicLib library做出：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
 
 
    MapView map = (MapView) findViewById(R.id.map);
    map.setTileSource(TileSourceFactory.MAPNIK);
    map.setBuiltInZoomControls(true);
    map.setMultiTouchControls(true);
 
 
    IMapController mapController = map.getController();
    mapController.setZoom(9);
    GeoPoint startPoint = new GeoPoint(-36.66372,174.69231);
    mapController.setCenter(startPoint);
 
    Polygon polyline = new Polygon(this);
    List<GeoPoint> points = new LinkedList<>();
 
    // I filled the data manually,but it can be done more clever,of course.
    GRC(points,new GeoPoint(-36.76736,174.83433));
    CWA(points,new GeoPoint(-36.93842,174.55269),new GeoPoint(-36.87200,174.48986),new GeoPoint(-36.80550,174.42714),0.08333);
    CCA(points,new GeoPoint(-36.68503,174.62581),new GeoPoint(-36.66514,174.64464),new GeoPoint(-36.68342,174.66586),0.02500);
    CCA(points,new GeoPoint(-36.66372,174.69231),new GeoPoint(-36.64542,174.67103),new GeoPoint(-36.65486,174.69992),0.02500);
    GRC(points,new GeoPoint(-36.66072,174.74381));
    CWA(points,new GeoPoint(-36.61911,174.79094),new GeoPoint(-36.70106,174.77139),174.83433),//close shape going to the start point
                0.08333);
 
    polyline.setPoints(points);
    polyline.setFillColor(0xA0FF00FF);
    polyline.setStrokeColor(Color.BLACK);
    polyline.setStrokeWidth(2f);
    map.getOverlays().add(polyline);
    map.invalidate();
}
 
private void CCA(List<GeoPoint> points,GeoPoint startPoint,GeoPoint centerPoint,GeoPoint endPoint,double radius) {
    points.add(startPoint);
 
    GeodesicData f = Geodesic.WGS84.Inverse(centerPoint.getLatitude(),centerPoint.getLongitude(),startPoint.getLatitude(),startPoint.getLongitude());
    GeodesicData t = Geodesic.WGS84.Inverse(centerPoint.getLatitude(),endPoint.getLatitude(),endPoint.getLongitude());
 
    double ffaz = f.azi1;
    double tfaz = t.azi1;
 
    final int decrement = 1;
    while (Math.abs((int)ffaz) != Math.abs((int)tfaz)) {
        GeodesicData llb = Geodesic.WGS84.Direct(centerPoint.getLatitude(),ffaz,f.s12);
        points.add(new GeoPoint(llb.lat2,llb.lon2));
        ffaz -= decrement;
        if (ffaz <0) {
            ffaz += 360;
        }
    }
 
    points.add(endPoint);
}
 
private void CWA(List<GeoPoint> points,endPoint.getLongitude());
 
    double ffaz = f.azi1;
    double tfaz = t.azi1 > 0 ? t.azi1 : 360 + t.azi1;
 
    final int increment = 1;
    while (Math.abs((int)ffaz) != Math.abs((int)tfaz)) {
        GeodesicData llb = Geodesic.WGS84.Direct(centerPoint.getLatitude(),llb.lon2));
        ffaz += increment;
        if (ffaz>360) {
            ffaz -= 360;
        }
    }
 
    points.add(endPoint);
}
 
private void GRC(List<GeoPoint> points,GeoPoint geoPoint) {
    points.add(geoPoint);
}

我使用osmdroid OSMBonusPack,但代码是相当普遍的,可以轻松地与Google地图一起使用.

The full source code.

结果：

另外,你会介意告诉你发布了哪个地理数据？地图上的形状看起来像一个允许的飞行区域,我猜.
