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 geodesic method to the MultiLineString object.
var multiLineStringGeodesic = multiLineString.geodesic();
// Print the result to the console.
print('multiLineString.geodesic(...) =', multiLineStringGeodesic);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
{'color': 'black'},
'Geometry [black]: multiLineString');

When `true`, edges are curved, following the shortest path on Earth's surface; when `false`, edges are straight. The method accepts a `Geometry` object as its input, it is applied to a `MultiLineString` object, and is illustrated by a Javascript and Python code examples where a `MultiLineString` is created, the method applied, and the result printed.\n"],null,[]]
