ee.Geometry.Rectangle.edgesAreGeodesics
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
如果几何图形的边（如果有）是地球球面模型上的测地线，则返回 true；如果为 false，则任何边都是投影中的直线。
| 用法 | 返回 |

Rectangle.edgesAreGeodesics() | 布尔值 |
示例
代码编辑器 (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');
