ee.Geometry.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 Geometry object.
var geometry = ee.Geometry({
  'type': 'Polygon',
  'coordinates':
    [[[-122.081, 37.417],
      [-122.086, 37.421],
      [-122.084, 37.418],
      [-122.089, 37.416]]]
});

// Apply the edgesAreGeodesics method to the Geometry object.
var geometryEdgesAreGeodesics = geometry.edgesAreGeodesics();

// Print the result to the console.
print('geometry.edgesAreGeodesics(...) =', geometryEdgesAreGeodesics);

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