ee.Geometry.closestPoints
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。
返回一个字典，其中包含最多两个条目，分别表示每个输入几何图形上距离另一个输入几何图形最近的点。如果任一几何图形为空，则返回空字典。如果两个几何图形都不受限，则字典中“left”和“right”都有任意点。如果一个几何图形是无界的，则字典中包含有界几何图形中的任意点，用于表示“左侧”和“右侧”。
| 用法 | 返回 |
|---|
Geometry.closestPoints(right, maxError, proj) | 对象 |
| 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。 |
