ee.Geometry.MultiPoint.closestPoint
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
傳回右側輸入內容中與左側輸入內容最接近的點。如果任一輸入為空，則會傳回 null。如果兩個輸入都不受限，則會傳回任意點。如果其中一個輸入內容不受限，則會傳回受限輸入內容中的任意點。
| 用量 | 傳回 |

MultiPoint.closestPoint(right, maxError, proj) | 物件 |
| 引數 | 類型 | 詳細資料 |
|---|
這個：left | 幾何圖形 | 做為運算左運算元的幾何圖形。 |
right | 幾何圖形 | 用做運算右運算元的幾何圖形。 |
maxError | ErrorMargin，預設值：null | 執行任何必要重投影時可容許的最大誤差量。 |
proj | 投影，預設值：null | 執行作業的投影。如未指定，系統會以球面座標系統執行作業，而球面上的線性距離會以公尺為單位。 |
