ee.Image.max
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
針對 image1 和 image2 中每個相符的頻帶組合，選取第一個和第二個值的最大值。如果 image1 或 image2 只有 1 個頻帶，則會與另一張圖片中的所有頻帶進行比較。如果圖片的波段數量相同，但名稱不同，系統會依自然順序成對使用。輸出頻帶會以較長的輸入命名，如果長度相同，則會以 image1 的順序命名。輸出像素的類型是輸入類型的聯集。
| 引數 | 類型 | 詳細資料 |

這個：image1 | 圖片 | 用來擷取左運算元頻帶的圖片。 |
image2 | 圖片 | 系統會從這張圖片擷取右運算元頻帶。 |
