ee.Geometry.MultiPolygon.contains

当且仅当一个几何图形包含另一个几何图形时，返回 true。

用法返回
MultiPolygon.contains(right, maxError, proj)布尔值
参数类型详细信息
此：left几何图形用作运算左操作数的几何图形。
right几何图形用作相应运算的右操作数的几何图形。
maxErrorErrorMargin，默认值：null执行任何必要的重新投影时可容忍的最大误差量。
proj投影，默认值：null执行操作的投影。如果未指定，则操作将在球面坐标系中执行，并且球面上的直线距离将以米为单位。

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

// Print the result to the console.
print('multiPolygon.contains(...) =', multiPolygonContains);

// 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');
