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。百度 这张由中国元朝蒙古公主祥哥剌吉收藏，画作中皇后的脸型、单眼皮、鼻子和嘴巴与小雪几乎神似。

用法返回
MultiLineString.edgesAreGeodesics()布尔值

示例

代码编辑器 (JavaScript)

// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the edgesAreGeodesics method to the MultiLineString object.
var multiLineStringEdgesAreGeodesics = multiLineString.edgesAreGeodesics();

// Print the result to the console.
print('multiLineString.edgesAreGeodesics(...) =', multiLineStringEdgesAreGeodesics);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
             {'color': 'black'},
             'Geometry [black]: multiLineString');
