ee.Geometry.MultiPolygon.containedIn

如果一個幾何體包含在另一個幾何體中，則傳回 true，反之則傳回 false。

用量傳回
MultiPolygon.containedIn(right, maxError, proj)布林值
引數類型詳細資料
這個：left幾何圖形做為運算左運算元的幾何圖形。
right幾何圖形用做運算右運算元的幾何圖形。
maxErrorErrorMargin，預設值：null執行任何必要重投影時可容許的最大誤差量。
proj投影，預設值：null執行作業的投影。如未指定，系統會以球面座標系統執行作業，而球面上的線性距離會以公尺為單位。

// Define a MultiPolygon object.
var multiPolygon = ee.Geometry.MultiPolygon(
    [[[[-122.092, 37.424],
       [-122.086, 37.418],
       [-122.079, 37.425],
       [-122.085, 37.423]]],
     [[[-122.081, 37.417],
       [-122.086, 37.421],
       [-122.089, 37.416]]]]);

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the containedIn method to the MultiPolygon object.
var multiPolygonContainedIn = multiPolygon.containedIn({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('multiPolygon.containedIn(...) =', multiPolygonContainedIn);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPolygon,
             {'color': 'black'},
             'Geometry [black]: multiPolygon');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
