ee.Geometry.BBox.intersects
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
当且仅当几何图形相交时返回 true。
| 用法 | 返回 |
|---|
BBox.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。 |
maxError | ErrorMargin，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 BBox object.
var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43);
// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);
// Apply the intersects method to the BBox object.
var bBoxIntersects = bBox.intersects({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('bBox.intersects(...) =', bBoxIntersects);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(bBox,
{'color': 'black'},
'Geometry [black]: bBox');
Map.addLayer(inputGeom,
{'color': 'blue'},
'Parameter [blue]: inputGeom');
