ee.Geometry.Point.intersection

返回两个几何图形的交集。

用法返回
Point.intersection(right, maxError, proj)几何图形
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 Point object.
var point = ee.Geometry.Point(-122.082, 37.42);

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

// Apply the intersection method to the Point object.
var pointIntersection = point.intersection({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('point.intersection(...) =', pointIntersection);

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