ee.Geometry.LinearRing.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 |
---|
LinearRing.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 LinearRing object.
var linearRing = ee.Geometry.LinearRing(
[[-122.091, 37.420],
[-122.085, 37.422],
[-122.080, 37.430]]);
// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);
// Apply the intersects method to the LinearRing object.
var linearRingIntersects = linearRing.intersects({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('linearRing.intersects(...) =', linearRingIntersects);
// Display relevant geometries on the map.

Map.addLayer(linearRing,
{'color': 'black'},
'Geometry [black]: linearRing');
Map.addLayer(inputGeom,
