示例
代码编辑器 (JavaScript)
// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
[[-122.091, 37.420],
[-122.085, 37.422],
[-122.080, 37.430]]);
// Apply the geodesic method to the LinearRing object.
var linearRingGeodesic = linearRing.geodesic();
// Print the result to the console.
print('linearRing.geodesic(...) =', linearRingGeodesic);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(linearRing,
{'color': 'black'},
'Geometry [black]: linearRing');
