ee.Geometry.MultiLineString.containedIn
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。
当且仅当一个几何图形包含在另一个几何图形中时，返回 true。
| 用法 | 返回 |
|---|
MultiLineString.containedIn(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。 |
