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。

示例
代码编辑器 (JavaScript)
// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);
// Apply the edgesAreGeodesics method to the Point object.
var pointEdgesAreGeodesics = point.edgesAreGeodesics();
// Print the result to the console.
print('point.edgesAreGeodesics(...) =', pointEdgesAreGeodesics);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(point,
{'color': 'black'},
'Geometry [black]: point');
