ee.Geometry.containedIn
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如果一個幾何體包含在另一個幾何體中,則傳回 true,反之則傳回 false。
用量 | 傳回 |
---|
Geometry.containedIn(right, maxError, proj) | 布林值 |
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。 |
