ee.Geometry.Rectangle.edgesAreGeodesics
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如果幾何邊緣 (如有) 是沿著地球球體模型繪製的測地線，則傳回 true；如果為 false，則任何邊緣都是投影中的直線。

範例
程式碼編輯器 (JavaScript)
// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);
// Apply the edgesAreGeodesics method to the Rectangle object.
var rectangleEdgesAreGeodesics = rectangle.edgesAreGeodesics();
// Print the result to the console.
print('rectangle.edgesAreGeodesics(...) =', rectangleEdgesAreGeodesics);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
{'color': 'black'},
'Geometry [black]: rectangle');
