ee.Geometry.MultiLineString.edgesAreGeodesics

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 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');
