ee.Geometry.MultiPoint.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 MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);
// Apply the edgesAreGeodesics method to the MultiPoint object.
var multiPointEdgesAreGeodesics = multiPoint.edgesAreGeodesics();
// Print the result to the console.
print('multiPoint.edgesAreGeodesics(...) =', multiPointEdgesAreGeodesics);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPoint,
{'color': 'black'},
'Geometry [black]: multiPoint');
