ee.Feature.cutLines
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
將 LineString、MultiLineString 和 LinearRing 幾何圖形轉換為 MultiLineString,方法是沿著長度將這些幾何圖形切成多個部分,且每個部分不得超過指定距離。所有其他幾何類型都會轉換為空白的 MultiLineString。

這個:feature | 元素 | 剪除這項功能預設幾何圖形的線條。 |
distances | 清單 | 沿著每個 LineString 將線條切成不同片段的距離,以指定 proj 的單位測量,如果未指定 proj,則以公尺為單位。 |
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 | 結果和距離測量的投影,如未指定,則為 EPSG:4326。 |
