ee.Geometry.geodesic

如果为 false，则投影中的边缘是直的。如果为 true，则边会弯曲，以遵循地球表面的最短路径。

用法	返回
Geometry.geodesic()	布尔值

参数	类型	详细信息
此：geometry	几何图形

示例

代码编辑器 (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 geodesic method to the Geometry object.
var geometryGeodesic = geometry.geodesic();

// Print the result to the console.
print('geometry.geodesic(...) =', geometryGeodesic);

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