ee.Geometry.Polygon.intersects

当且仅当几何图形相交时返回 true。

用法返回
Polygon.intersects(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。

示例

代码编辑器 (JavaScript)

// Define a Polygon object.
var polygon = ee.Geometry.Polygon(
    [[[-122.092, 37.424],
      [-122.086, 37.418],
      [-122.079, 37.425],
      [-122.085, 37.423]]]);

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

// Apply the intersects method to the Polygon object.
var polygonIntersects = polygon.intersects({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('polygon.intersects(...) =', polygonIntersects);

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