ee.Geometry.LineString.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
LineString.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 LineString object.
var lineString = ee.Geometry.LineString([[-122.09, 37.42], [-122.08, 37.43]]);

// Apply the geodesic method to the LineString object.
var lineStringGeodesic = lineString.geodesic();

// Print the result to the console.
print('lineString.geodesic(...) =', lineStringGeodesic);

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