CSV 檔案應包含每個特徵的資料列,以及特徵集合中屬性或變數的資料欄數量。如果地圖項目是地理空間,則必須具有由幾何圖形字串 (GeoJSON、WKT) 或 x 和 y 位置屬性定義的地理位置。如果 CSV 檔案是從 GDAL/OGR 等 GIS 或地理空間資料工具匯出的資料,則應已存在格式正確且命名為幾何圖形的資料欄。或者,您也可以在試算表應用程式中定義兩個代表 x 和 y 座標的資料欄,並將其與其他變數一併匯出為 CSV 格式。
除非另有指定,否則 Earth Engine 會嘗試偵測主要幾何圖形資料欄,並假設資料投影為 WGS84。幾何圖形的測地線狀態取決於指定投影的預設邊緣解讀方式 (例如 WGS84 使用測地線幾何圖形),但這可在「進階設定」選單中覆寫。如果資料的幾何圖形是透過 x 和 y 欄定義的點,請務必將各資料欄命名為「經度」和「緯度」,或在「進階」設定下指定 x 和 y 欄名稱。
