ee.Geometry.Point.edgesAreGeodesics

如果几何图形的边（如果有）是地球球面模型上的测地线，则返回 true；如果为 false，则任何边都是投影中的直线。

用法返回
Point.edgesAreGeodesics()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 Point object.
var point = ee.Geometry.Point(-122.082, 37.42);

// Apply the edgesAreGeodesics method to the Point object.
var pointEdgesAreGeodesics = point.edgesAreGeodesics();

// Print the result to the console.
print('point.edgesAreGeodesics(...) =', pointEdgesAreGeodesics);

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